Details are given of errors and additions to the recently published checklist of lichens reported from South Africa (Fryday 2015). The overall number of taxa reported from South Africa is increased by 1, to 1751.

 Introduction

The compilation of the recent South African lichen checklist (Fryday 2015) was always considered a first step in producing an up-to-date, comprehensive checklist for the country. It was inevitable that some records and other taxonomic and nomenclatural changes would be overlooked and, through the Lichens-L listserve, lichenologists were encouraged to send any additions or corrections to the author that would be published as a first supplement to the list. This paper is the result of those contributions. These mostly refer to corrections to the text and nomenclatural updates but also included the records from a publication on Usnea (Motyka 1961) that was overlooked in the production of the original checklist, and the results of the revision in 2004 by the first author of a large number of Cladoniaceae from the Bolus Herbarium (BOL) of which very little has been published. Duplicates of many specimens were retained in the University of Helsinki Herbarium (H) whereas much of the lichen collection of the Bolus Herbarium has been transferred to the herbarium of the South African National Biodiversity Institute (SANBI), Pretoria (PRE). Another major South African Cladonia collection in Lund (LD) is still being studied by the first author in Helsinki.

In addition to the printed list (Fryday 2015), an online list, which will be regularly updated and includes the changes proposed here, is also now available (Fryday 2016). Future hard copy supplements will include only substantial changes (e.g. new addition to the lichen biota of South Africa and other changes that require explanation), and other changes (corrections to author citations, etc.) will be made to the online list only.

 Corrections to the Checklist General

Weber ex F. H. Wigg.: All author citations (in Cladonia, Collema and Usnea) should be corrected to F. H. Wigg. For example: Cladonia rangiferina (L.) Weber ex F.H. Wigg. should be Cladonia rangiferina (L.) F.H. Wigg.

 Additions (43)

Cetraria muricata (Ach.) Eckfeldt: Reported by Kärnefelt (1986) as Coelocaulon muricatum (Ach.) J. R. Laundon.

Cladonia borbonica Nyl.: Abbayes (1964) described C. poeciloclada from South Africa but, although recognized by Swinscow & Krog (1988), this species was synonymized with C. borbonica by Ahti & Aptroot (1992).

Cladonia conista (Nyl.) Robbins: A widespread segregate of C. humilis that was reported from South Africa by Pino-Bodas et al. (2012). Representative specimen: Western Cape, Cape Peninsula, S end of Constantiaberg, 1945, F. M. Leighton 855 p.p. (PRE, H).

Cladonia corniculata Ahti & Kashiw.: A widespread species in the Southern Hemisphere. Representative specimen: KwaZulu-Natal, Bergville District, Drakenberg, Little Tugela Area, 5000 ft., 1943, E. Esterhuysen 8857 (PRE, H).

Cladonia crispata (Ach.) Flot.: A widespread species in the Northern Hemisphere. Representative specimen: KwaZulu-Natal, Bergville District, top of Mweni Pass, Drakensberg, 10 000 ft., 1958, E. Esterhuysen 27847 (PRE, H). The material seen contains squamatic acid (TLC) and represents var. crispata.

Cladonia cryptochlorophaea Asahina: A widespread, cosmopolitan segregate of C. chlorophaea (Flörke ex Sommerf.) Spreng. Representative specimen: Western Cape, Uniondale Division, Slypsteenberg, Uniondale Hot Springs 1941, E. Esterhuysen 7129 (H, PRE); presence of cryptochlorophaeic acid confirmed with TLC (with some uncertainty).

Cladonia grayi G. Merr. ex Sandst.: A widespread, cosmopolitan segregate of C. chlorophaea. Representative specimen: Western Cape, Cape Peninsula, S end of Noordhoek Peak, 1900 ft., 1945, F. M. Leighton 927 (H, PRE). Presence of grayanic acid confirmed with TLC.

Cladonia humilis (With.) J. R. Laundon: A widespread species in temperate regions of the world that was reported from South Africa by Pino-Bodas et al. (2012). Here treated in the strict sense (i.e., excluding C. conista, which is cited above). In South Africa, more common than C. conista. Representative specimen: Western Cape, Stellenbosch Division, Stellenbosch Flats, top of first river terrace, 1944, S. Garside 6106 (PRE, H). Presence of atranorin confirmed with TLC.

Cladonia intermediella Vain.: Widespread in East Africa (Swinscow & Krog 1988). Representative specimen: Western Cape, Cape Peninsula, Table Mountain, summit, 1942, S. Garside s. n. (PRE, H). The South African specimens are not well-developed and therefore not fully certainly distinct from C. pyxidata (L.) Hoffm. s. lat.

Cladonia merochlorophaea Asahina: A widespread, cosmopolitan segregate of C. chlorophaea. Representative specimen: Western Cape, Clanwilliam Division, Cederberg, Kromme Rivier, 3500 ft., 1949, T. P. Stokoe 9444 (H, PRE). Presence of merochlorophaeic acid confirmed with TLC.

Cladonia poeciloclada f. brachiata Abbayes: Cladonia poeciloclada f. poeciloclada Abbayes was synonymized with C. borbonica Nyl. (Ahti & Aptroot 1992), but the identity of the f. brachiata, which was also described from South Africa, is unresolved and so is included as a distinct taxon pending further study.

Cladonia subpungens Abbayes: This species was described from South Africa (Abbayes 1964; Ahti 1993).

Dimelaena tenuis (Müll. Arg.) H. Mayrhofer & Wippel: Overlooked by Fryday (2015). One record from KwaZulu-Natal (Mayrhofer et al. 1996).

Heppia guepinii var. nigrolimbata Nyl.: Of uncertain application but probably distinct from H. guepinii (Delise) Nyl. (= Peltula euploca (Ach.) Poelt; see below). It is provisionally included as a distinct taxon pending further study.

Lepraria sipmaniana (Kümmerl. & Leuckert) Kukwa: Overlooked by Fryday (2015). Described from KwaZulu-Natal (Leuckert & Kümmerling 1991).

Rinodina atroalbida (Nyl.) C.W.Dodge: Described from South Africa but the type could not be located (Mayrhofer 1984, Matzer & Mayrhofer 1996).

Rinodina australiensis Müll.Arg.: Reported by Mayrhofer et al. (2014).

Rinodina scabridula Matzer & H. Mayrhofer: Reported by Matzer & Mayrhofer (1996).

Rinodina striatitunicata Matzer & H. Mayrhofer: Reported by Matzer & Mayrhofer (1996).

Rinodina substellulata Müll. Arg.: Reported by Matzer & Mayrhofer (1996).

Rinodina subtristis (Nyl.) H. Mayrhofer: Reported by Matzer & Mayrhofer (1996).

Siphula torulosa (Thunb. ex Ach.) Nyl.: Recognized as a good species by Mathey (1971) and Kantvilas (2002), not a synonym of S. decumbens Nyl. Stereocaulon pulvinatum Ach. should be included as a synonym.

The following Usnea species were all reported by Motyka (1961) from collections made by R. A. Mass Geesteranus in 1949 – a publication that was overlooked in the production of the original checklist (Fryday 2015). All collections are in the Nationaal Herbarium Nederland, Leiden (L). Full collection details can be found in Motyka (1961), which is available online.

 Deletions (42)

Buellia subtristis (Nyl.) Zahlbr.: = Rinodina subtristis (Nyl.) H. Mayrhofer (Mayrhofer 1984, Matzer & Mayrhofer 1996).

Cladonia bacillaris (Ach.) Genth: Usually recognised as a barbatic acid chemotype of C. macilenta Hoffm. The presence of both thamnolic and barbatic acid chemotypes in South Africa has been reported (Stenroos 1994).

Cladonia caespiticia (Pers.) Flörke: Not substantiated from South Africa.

Cladonia coniocraea (Flörke) Spreng.: All the Southern Hemisphere records of this species appear to belong to the closely related C. ochrochlora Flörke (cf. Ahti 2000), which has been substantiated from South Africa. However, the taxonomy of this complex is still incompletely understood.

Cladonia furcata (Huds.) Schrad.: Not substantiated for South Africa. It is expected that the records are referable to C. subpungens Abbayes.

Cladonia flabelliformis Vain.: nom. illeg. (not (Flörke) Vain.): A recognised synonym of C. polydactyla (Flörke) Spreng., but the name is misapplied and C. polydactyla does not occur in South Africa.

Cladonia multiformis G. Merr.: A misapplied name. Cladonia multiformis is known only from North America. Both African and more recent Asian reports have been found to be incorrect.

Cladonia pertricosa Kremp.: South African records are referable to C. subpungens. Cladonia pertricosa is an Australian endemic.

Cladonia polia R. Sant.: A synonym of C. confusa R. Sant. representing its usnic acid deficient strain (called Cladina confusa f. bicolor (Müll. Arg.) Ahti in Ahti 2000). This strain exists in South Africa, though it was not reported by Ahti (2000).

Cladonia portentosa (Dufour) Coëm.: First reported from South Africa by Abbayes (1939), as C. impexa Harm. South African records are referable to C. confusa.

Cladonia pycnoclada (Pers.) Nyl.: South African records are referable to C. confusa. The given synonym f. exalbescens Vain. is a synonym of C. confusa.

Cladonia rangiferina (L.) F.H. Wigg. (NOT Weber ex F.H. Wigg.): South African records are probably referable to C. confusa.

Cladonia rangiformis Hoffm.: South African records are referable to C. subpungens.

Cladonia rei Schaer.: Inadvertently included with C. rangiformis by Fryday (2015). Cladonia fimbriata var. nemoxyna (Ach.) Coem. and C. fimbriata var. nemoxyna f. fibula (Ach.) Vain. are synonyms of this species not C. rangiformis. However, C. rei has not been substantiated for South Africa.

Cladonia subradiata (Vain.) Sandst.: Not substantiated from South Africa. The given synonym C. fimbriata var. balfourii (Cromb.) Vain. belongs to C. macilenta, but the name has been used for C. subradiata in North America.

Cladonia subulata (L.) F. H. Wigg.: Not substantiated for South Africa. The records are probably referable to C. corniculata Ahti & Kashiw.

Heppia euploca Vain.: A synonym of Peltula euploca (Ach.) Poelt. Vainio (1921) under a note on Lichen euplocus Ach. gives a brief description comparing it to Heppia guepinii and then writes ‘quae eam ob causam est Heppia euploca (Ach.)’ [which is why it is Heppia euploca (Ach.)] so, clearly, he was making a new combination rather than describing a new species.

Heppia guepinii (Delise) Nyl.: A synonym of Peltula euploca (Ach.) Poelt.

Lithographa fumida Nyl.: Not validly published (nomen nudum). Stizenberger (1891) says, ‘1211. L. fumida Nyl. in Hb. Lojka — Saxicola socia Siphulae tabularis in Monte Tabulari ad Promontorium Bonae Spei, McOwen. – Endem’., which does not constitute a valid description.

Pannaria capensis J. Steiner: This species, which was described from South Africa, is a synonym of Pannaria lurida (Mont.) Nyl. subsp. lurida (Jørgensen 2004)

Peccania arabica (Müll. Arg.) Henssen: The type collection is a poor mixture of at least two cyanolichens and Müller Argoviensis’ diagnosis combines features from both; the small squamulose-lobate part is a Collema and the fertile, minutely squamulose part is a Peccania. Unfortunately, the Peccania is so meagre (there is only one small apothecia left) that it is not possible to confidently determine its identity, especially since there are several other small Peccania spp. from Arabia and northern Africa (e.g., ‘Synalissa’ arabica, Peccania sinaiensis, P. tiruncula).

Peltigera leptoderma Nyl.: Listed as a synonym of P. didactyla (With.) J.R. Laundon but according to Vitikainen (1994) this is a misapplication, although the exact taxonomic status of the name is still uncertain.

Pyxine nubila Moberg: A synonym of Culbersonia nubila (Moberg) Essl., which was already included in Fryday (2015).

Rinodina detecta (Stizenb.) Zahlbr.: A synonym of R. oxydata (Matzer & Mayrhofer 1996).

Rinodina deminutula (Stizenb.) Zahlbr.: The scant type (from Western Cape) is in poor condition and a treatment of this species is not possible (Mayrhofer 1984).

Rinodina exigua (Ach.) S. F. Gray: The single South African collection was referred to R. ficta by Mayrhofer et al. (2014).

Rinodina exiguella (Vain.) H. Magn.: Not treated by Matzer & Mayrhofer (1996) or Mayrhofer et al. (2014). This species was described from the Arctic and its presence in South Africa is highly unlikely.

Rinodina huefferiana Müll. Arg.: The single South African collection was referred to R. ficta (Stizenb.) Zahlbr. by Mayrhofer et al. (2014).

Rinodina roboris Arnold: South African collections were referred to R. australiensis by Mayrhofer et al. (2014).

Rinodina sophodes (Ach.) A. Massal.: No South African collections of this northern hemisphere species could be traced by Mayrhofer et al. (2014) who rejected the species.

Rinodina sophodes var. atroalbida (Nyl.) Zahlbr.: type cannot be located (Mayrhofer 1984). Another South African collection was referred to R. huillensis by Mayrhofer et al. (2014).

Roccella arnoldii Vain.: A synonym of Roccella tinctoria DC. (Tehler et al. 2004), which does not occur in South Africa. All specimens seen are referable to R. montagnei Bél. (cortex C+ red; soralia C–).

Roccella capensis Follm.: A synonym of Roccellina hypomecha (Ach.) Bory (Tehler and Irestedt 2007).

Roccella fuciformis (L.) Lam. & DC.: Does not occur in South Africa (Tehler et al. 2004).

Roccella phycopsis Ach.: does not occur in South Africa (Tehler et al. 2004). All specimens seen are referable to R. montagnei (cortex C+ red; soralia C–).

Roccella fucoides (Dicks.) Vain.: A synonym of Roccella phycopsis Ach. (Tehler 2003), which does not occur in South Africa (Tehler et al. 2004). All specimens seen are referable to R. montagnei (cortex C+ red; soralia C–).

Roccella tinctoria DC.: Does not occur in South Africa (Tehler et al. 2004; Tehler et al. 2010). All specimens seen are referable to R. montagnei (cortex C+ red; soralia C–).

Siphula ceratites (Wahlenb.) Fr.: Misidentifications (Mathey 1971, Kantvilas 2002).

Siphula dregei Laur. (nomen nudum): Included in the synonymy of S. verrucigera by Mathey (1971) and Kantvilas (2002).

Siphula incrustans Vain.: Included in the synonymy of S. verrucigera by Kantvilas (2002).

Siphula minor Vain.: Included in the synonymy of S. verrucigera by Mathey (1971) and Kantvilas (2002).

 Errata

Arthothelium fusco-nigrum (Nyl.) Müll. Arg.: Should be Arthothelium fusconigrum.

Cladonia fimbriata var. chlorophaeoides Vain. and var. chondroidea Vain.: Listed as synonyms of C. fimbriata (L.) Fr. but, although still not typified, they cannot belong to C. fimbriata. They probably represent C. subsquamosa Kremp. (Ahti 2000) but that species is not known from South Africa. It is expected that the material belongs to C. chlorophaea (L.) Fr.

Cladonia leptoclada Abbayes: Not included by Fryday (2015) but the South African record reported by Ahti (1961) is referable to C. confusa.

Cladonia pocillum (Ach.) O.J. Rich.: The author citation should be (Ach.) Grognot, NOT (Ach.) O.J. Rich.

Cladonia rangiformis var. pungens (Ach.) Vain.: Listed as a synonym of C. pertricosa. This taxon is a synonym of C. rangiformis but the South African records probably do refer to C. subpungens.

Lecanora atraeformis Vain.: Should be corrected to Lecanora atriformis (ICN Rec. 60G).

Lecidea affine G. Merr.: Corrected spelling is Lecidea affinis, which would be a later homonym of L. affinis Schaer. (1850), if validated.

Lecidea fuscoatra Ach.: Correct spelling of the epithet of the synonym is mosigii Zahlbr.

Lecanora caesiorubella Ach.: Incorrectly placed. It should be before L. campestris (Schaer.) Hue.

Megalospora tuberculosa (Fée) Sipman: Included twice under Megalospora.

Melampylidium africana (Zahlbr.) Zahlbr.: Should be M. africanum (Zahlbr.) Zahlbr.

Pannaria globigera Hue: Should be P. globuligera Hue.

Pannaria leucosticta (Tuck.) Nyl. var. isidiopsis Nyl.: This taxon, which was described from South Africa, is a synonym of P. globuligera Hue NOT Fuscopannaria leucosticta (Tuck.) P.M. Jørg. (Jørgensen & Galloway 1992, Jørgensen 2004).

Pannaria rubiginosa (Thunb. ex Ach.) Delise: The correct author citation is Pannaria rubiginosa (Ach.) Bory. Add Jørgensen 2004 to references (type specimen from South Africa cited).

Pannaria rubiginosa var. phloeodes (Stirt.) Stizenb.: This taxon, which was described from South Africa, is a synonym of Pannaria lurida (Mont.) Nyl. subsp. lurida NOT P. rubiginosa (Thunb. ex Ach.) Delise (Jørgensen 2004).

Pannaria pulvinula P.M. Jørg.: Add Jørgensen 2004 to references (type specimen from South Africa (Prince Edward Islands) cited).

Peltula euploca (Ach.) Poelt ex Pišút: Not Peltula euploca (Ach.) Poelt ex Ozenda & Clauzade. The invalid combination (no basionym) of Poelt (1963) was validated by Pišút (1967) who reported the species from Bulgaria as Peltula euploca (Ach.) Poelt, correctly cited the basionym, but did not mention the location of Poelt’s invalid combination.

Phaeophyscia adiostola (Essl.) Essl.: The correct spelling is Phaeophyscia adiastola (Essl.) Essl.

Ramalina roesleri (Hochst. ex Schaer.) Nyl.: Correct author citation is (Schaer.) Nyl.

Rinodina confragulosa Müll. Arg.: Should be R. confragosula (Nyl.) Müll. Arg.

Rinodina microlepida Müll. Arg.: Should be R. microlepidea Müll. Arg.

Solorina sorediifera Nyl.: This should be removed from synonymy of Peltigera didactyla (With.) J.R. Laundon. It is already included as P. sorediifera (Nyl.) Vitik.

Sticta hornemanni Fr.: The correct spelling of the epithet is hornemannii.

Tapellaria epiphlla (Müll. Arg.) R. Sant.: This should be T. epiphylla (Müll. Arg.) R. Sant.

Tuckermannopsis chlorophylla (Willd.) Hale: The correct author citation is (Willd. ex Humb.) Hale. Also the synonym should be Cetraria chlorophylla (Willd. ex Humb.) Poetsch.

Usnea barbata (L.) F.H. Wigg.: Usnea plicata F.H.Wigg., which was included as a synonym of this species, has been typified to U. ceratina Ach., but is nom. utique rej.

Usnea dasopoga (Ach.) Röhl.: the correct author citation for this and the orthographic varient U. daypoga is (Ach.) Nyl.

Usnea florida (L.) F.H. Wigg.: the correct author citation for U. florida var. scabrosa which was included as a synonym of this species is (Ach.) Vain., but this is a nom. inval.

Usnea subfloridana Stirt: Add period after author i.e., Stirt. The correct author citation for the synonym Usnea comosa is (Ach.) Vain.

Usnea trichodeoides Vain. ex Motyka: The correct author citation is Vain. and that of the synonym, Dolichousnea trichodeoides (Vain.) Articus.

The following Usnea species were all reported by Motyka 1961, and so this publication should be added to the references for these species:

Usnea delicata Vain.: (localities cited).

Usnea distensa Stirt.: (localities cited).

Usnea horridula (Müll. Arg.) Motyka: (localities cited).

Usnea maculata Stirt.: (localities cited).

Usnea molliuscula Stirt.: (localities cited).

Usnea moniliformis Motyka: (localities cited).

Usnea praelonga Stirt.: (localities cited).

Usnea promontorii Motyka: (localities cited).

Usnea rubicunda Stirt.: (localities for the synonym U. spilota Stirt. cited).

Usnea strigosella J. Steiner: (localities cited).

Usnea subleprosa Motyka: (localities cited).

Usnea trichodeoides Vain.: (localities cited).

Usnea desaea Stirt.: (localities for the synonym U. undulata Stirt. cited).

The second section of Motyka’s Usnea monograph was published in two parts; the first in 1937 and the second in 1938. Most of the South African species were included in the first part and so all references to Motyka 1938 should be changed to Motyka 1937 except for U. bornmuelleri, J. Steiner, U. cornea Motyka, U. filamentosa Motyka, U. primitiva Motyka and U. subleprosa Motyka, which were included in the second part.

Verrucaria compacta aggr. (A. Massal.) Jatta,: This should be (A. Massal.) Jatta, aggr.

Verrucaria viridula Ach.: The author citation should be (Schrad.) Ach.

Xanthoparmelia (Vain.) Hale: All author citations with ’G. Amo, et al.’ should be corected to G. Amo et al. (no comma). For example, X. adligans (Brusse) G. Amo et al. NOTE: G. Amo is sometimes cited as Amo de Paz, but G. Amo is used here throughout.

Xanthoparmelia cedri-montana Brusse: remove hyphen, X. cedrimontana. This is a nomen novum for Parmelia stenophyllo f. hypomelaena Vain. ex Lynge, which should be added to the synonyms.

Xanthoparmelia ceresina (Lynge) Hale: The correct author citation is (Vain. ex Lynge) Hale and that of Parmelia ceresina Vain. ex Lynge.

Xanthoparmelia conspersa (Ach.) Hale: Correct author citation for Parmelia conspersa is (Ach.) Ach.

Xanthoparmelia lichinoidea (Nyl.) O. Blanco et al.: The correct author citation is (Nyl. ex Cromb.) O. Blanco et al.

Xanthoparmelia plittii (Gyeln.) Hale: Delete Parmelia subconspersa var. africana Gyeln. From the synonyms because this is known only from Angola.

Xanthoparmelia schenkiana (Müll. Arg.) Hale: The correct spelling of the epithet is schenckiana.

Xanthoparmelia squamariata (Nyl.) O. Blanco et al.: The correct author citation is (Nyl. ex Cromb.) O. Blanco et al.

Xanthoparmelia waboombergensis (Essl.) O. Blanco et al.: In spite of the slight spelling difference, this is considered a later homonym of X. waboomsbergensis Elix and so is illegitimate and a new name is required for this taxon.

Xanthoria doidgea Eichenb., Aptroot & Honegger: Correct spelling of the epithet of new name is doidgeae.

Xanthoria elegans (Link) Th. Fr.: The correct author citation of Rusavskia elegans is (Link) S. Y. Kondr. & Kärnefelt.

Crombie J.M.1877: This was actually published in 1876, so should be Crombie J.M.1876b, with the previous reference becoming Crombie 1876a. This means the following references should also be changed: Xanthoparmelia lichinoidea & X. squamariata Crombie 1876a; X. constrictans Crombie 1876b.

Frey 1949: the correct title is ‘Neue Beiträge zu einer Monographie des Genus Umbilicaria Hoffm., Nyl’.

Kondratyuk et al. 2008: the second Xanthodactylon should be in italics.

 Other comments

Lichen monocarpus Ach. nom. utique rej.: This taxon was described from South Africa and is an earlier name for Cladonia didyma (Fée) Vain. (Stenroos 1994). A proposal by Ahti & DePriest (2005) to reject the name has been accepted.

 Results

The current paper includes 43 additions to and 42 deletions from the published list (Fryday 2015), with the result that the overall number of taxa reported from South Africa is increased by 1, to 1751.

 Conclusion

In spite of the corrections listed here, the main deficiency of the list remains: because it was a literature-based compilation of taxa reported from the country, and many records date from the 19th (or even 18th) century, there is little doubt that many of the species on the list do not occur in South Africa. This is a problem that can only be addressed by a programme of lichen research, both in the field and the laboratory. In particular, the type of specimens of the numerous species described from South African collections by Stizenberger, Zahlbruckner and other workers, which are mostly in European herbaria, should be examined and their identity ascertained, along with a comprehensive programme of field work that should focus on crustose groups because these are by far the most under-collected and -recorded.
