The lichenicolous fungi growing on Graphidales hosts in Florida are revised, mainly based on collections by the second author (R. C.). Twenty-one species are recognized. The new genus and species Lawreya glyphidiphila is described for a common asexual fungus growing on Glyphis scyphulifera and more rarely Trypethelium eluteriae , characterized by black stromatic conidiomata in which subspherical conidiogenous loculi develop, producing aseptate, subglobose, brown conidia. Nine additional new species are described: Amerosporiopsis phaeographidis (on Phaeographis brasiliensis ), Arthonia acanthotheciicola (on Acanthothecis floridensis ), A. subgraphidicola (on Graphis assimilis ), Hemigrapha graphidicola (on G. assimilis ), Skyttea graphidicola (on Graphis spp.), Strigula graphidicola (on G. assimilis ), S. perparvula (on Graphidales ), Talpapellis graphidis (on Graphis caesiella ) and Tremella wedinii (on Glyphis scyphulifera ). Phylogenetic placements of Lawreya glyphidiphila , Skyttea graphidicola and Tremella wedinii are presented. Identification keys are given for the species of Cornutispora and Talpapellis , and for the 66 species known to grow on Graphidales hosts worldwide.

Lichenochora caloplacae is reported for the first time from outside the Arctic. An unusual intrahymenial parasite of Lecanora pulicaris similar to Rhabdospora lecanorae is discussed. Bryoplaca is reported as a new host genus for Merismatium nigritellum agg., Cetrelia for Cornutispora lichenicola and Echinothecium reticulatum, Flavoparmelia for Cornutispora ciliata, and Pseudevernia for Lichenoconium cargillianum. A synopsis of 248 species from 98 genera of lichenicolous fungi and three species from two additional genera of allied fungi so far known from the Caucasus is presented and analyzed. The most species-rich genera are Stigmidium, Arthonia and Abrothallus. 81% of the lichenicolous fungi species were found on only one host genus. The value of the 'parasite genera:host genera' ratio is about 1:1. The most frequently parasitized lichen genera are Lecanora s. l., Parmelia, Peltigera, Cladonia and Physcia. About half of the species found in the Caucasus occur outside the Holarctic. The lichenicolous index for the Russian Caucasus is approximately 0.2. The most frequently collected species were Lichenostigma maureri, Marchandiomyces corallinus, Lichenoconium erodens, L. lecanorae and Nesolechia oxyspora. About 25% of the detected species were considered visible to the naked eye, 60% were clearly visible only at 10× magnification, and 15% only at 20−40× magnification.

Lichenicolous fungi represent a highly specialized and successful group of organisms that live exclusively on lichens, most commonly as host-specific parasites, but also as broad-spectrum pathogens, saprotrophs or commensals. We present here the most recent update to the classification of lichenicolous fungi in the Ascomycota and Basidiomycota to genus level, arranged phylogenetically according to published classifications. For each genus, all known lichenicolous taxa (obligately lichenicolous taxa, lichenicolous lichens, and facultatively lichenicolous taxa) are listed, along with information about types, synonyms, pertinent literature and whether or not molecular data are available for any of the listed species. The number of accepted lichenicolous fungi is now 2319, with 2000 obligately lichenicolous species, subspecies or varieties, 257 lichenicolous lichens and 62 facultatively lichenicolous taxa. These species are found in 10 different classes of Fungi (Ascomycota and Basidiomycota), 55 orders, 115 families and 397 genera. The 2319 total taxa is an increase from the 1559 total species reported in the last published catalogue in 2003, and a larger number than the approximately 1800 reported in the most recent online checklist (www.lichenicolous.net) posted in January 2018. Of the total number of taxa, 2219 (96%) are ascomycetes and 100 (4%) are basidiomycetes. Of the 397 genera containing lichenicolous species, c. 50% (198) are entirely lichenicolous. In addition, six families (Abrothallaceae, Adelococcaceae, Cyphobasidiaceae, Obryzaceae, Polycoccaceae, Sarcopyreniaceae) and two orders (Abrothallales, Cyphobasidiales) are entirely lichenicolous. Sequence information is available for lichenicolous species in 128 (32%) of the 397 genera containing lichenicolous species, and in 56 (28%) of the 198 entirely lichenicolous genera. Many species are known from only one host lichen, but it is likely that broader host ecologies will be discovered as new sequence information is obtained from ongoing microbiome studies. Phaeopyxis Rambold & Triebel is considered as a new synonym of Bachmanniomyces D.Hawksw., resulting in five new combinations B. australis (Rambold & Triebel) Diederich & Pino-Bodas (≡ P. australis), B. carniolicus (Arnold) Diederich & Pino-Bodas (≡ Biatora carniolica), B. muscigenae (Alstrup & E.S.Hansen) Diederich & Pino-Bodas (≡ P. muscigenae), B. punctum (A.Massal.) Diederich & Pino-Bodas (≡ Nesolechia punctum) and B. varius (Coppins, Rambold & Triebel) Diederich & Pino-Bodas (≡ P. varia). As a consequence of a phylogenetic analysis including new sequences, Dactylospora Körb. is regarded as a new synonym of Sclerococcum Fr.: Fr., resulting in one new name (S. acarosporicola Ertz & Diederich) and 46 new combinations. Sclerococcaceae Réblová, Unter. & W.Gams is considered as a new synonym of Dactylosporaceae Bellem. & Hafellner. The new Sclerococcum ophthalmizae Coppins is described. Sclerophyton occidentale Herre is lectotypified on the lichenicolous fungus present in the type specimen and becomes a younger synonym of Sclerococcum parasiticum. A replacement name is Arthonia polydactylonis Diederich & Ertz (≡ A. ceracea). Further new combinations are Abrothallus lobariae (Diederich & Etayo) Diederich & Ertz (≡ Phoma lobariae), A. psoromatis (Zhurb. & U. Braun) Diederich & Zhurb. (≡ P. psoromatis), Asteroglobulus pyramidalis (Etayo) Diederich (≡ Cornutispora pyramidalis), Didymocyrtis grumantiana (Zhurb. & Diederich) Zhurb. & Diederich (≡ Phoma grumantiana), Epithamnolia atrolazulina (Etayo) Diederich (≡ Hainesia atrolazulina), Gyalolechia epiplacynthium (Etayo) Diederich (≡ Fulgensia epiplacynthium), Nesolechia doerfeltii (Alstrup & P.Scholz) Diederich (≡ Phacopsis doerfeltii), N. falcispora (Triebel & Rambold) Diederich (≡ P. falcispora), N. oxyspora var. fusca (Triebel & Rambold) Diederich (≡ P. oxyspora var. fusca), Preussia peltigerae (Brackel) Diederich (≡ Sporormiella peltigerae), Scutula curvispora (D.Hawksw. & Miadl.) Diederich (≡ Libertiella curvispora), S. didymospora (D.Hawksw. & Miadl.) Diederich (≡ L. didymospora), Stigmidium haesitans (Nyl.) Diederich (≡ Verrucaria haesitans), and S. parvum (Henssen) Diederich (≡ Pharcidia parvum). © 2018 by The American Bryological and Lichenological Society, Inc.
Knowledge of the relationships and thus the classification of fungi, has developed rapidly with increasingly widespread use of molecular techniques, over the past 10–15 years, and continues to accelerate. Several genera have been found to be polyphyletic, and their generic concepts have subsequently been emended. New names have thus been introduced for species which are phylogenetically distinct from the type species of particular genera. The ending of the separate naming of morphs of the same species in 2011, has also caused changes in fungal generic names. In order to facilitate access to all important changes, it was desirable to compile these in a single document. The present article provides a list of generic names of Ascomycota (approximately 6500 accepted names published to the end of 2016), including those which are lichen-forming. Notes and summaries of the changes since the last edition of ‘Ainsworth & Bisby’s Dictionary of the Fungi’ in 2008 are provided. The notes include the number of accepted species, classification, type species (with location of the type material), culture availability, life-styles, distribution, and selected publications that have appeared since 2008. This work is intended to provide the foundation for updating the ascomycete component of the “Without prejudice list of generic names of Fungi” published in 2013, which will be developed into a list of protected generic names. This will be subjected to the XIXth International Botanical Congress in Shenzhen in July 2017 agreeing to a modification in the rules relating to protected lists, and scrutiny by procedures determined by the Nomenclature Committee for Fungi (NCF). The previously invalidly published generic names Barriopsis, Collophora (as Collophorina), Cryomyces, Dematiopleospora, Heterospora (as Heterosporicola), Lithophila, Palmomyces (as Palmaria) and Saxomyces are validated, as are two previously invalid family names, Bartaliniaceae and Wiesneriomycetaceae. Four species of Lalaria, which were invalidly published are transferred to Taphrina and validated as new combinations. Catenomycopsis Tibell & Constant. is reduced under Chaenothecopsis Vain., while Dichomera Cooke is reduced under Botryosphaeria Ces. & De Not. (Art. 59).
The genus Talpapellis Alstrup & M.S.Cole (1998: 227) was introduced for a lichenicolous hyphomycete on Peltigera venosa collected in British Columbia, Canada (Alstrup & Cole 1998). Details of the conidiogenesis, the generic affinity and application of this genus name have previously been unclear and largely confused. Based on a revision and reassessment of type material and examination of additional collections from North America and Asia, Heuchert et al . (2014) published an amended circumscription of Talpapellis , discussed the conidiogenesis of this genus, described a new variety of T. peltigerae Alstrup & M.S.Cole (1998: 227) and provided a key to the recognised taxa of Talpapellis and confusable species of Verrucocladosporium K.Schub. et al. (Crous et al . 2007, Braun et al . 2009).
