This contribution presents new records of lichenized and “lichen-allied” fungi for the Czech Republic and a list of all recently published species missing in the last national checklist (Liška & Palice 2010). Lecanora tephraea is supposed to be synonymous with L. cenisia and the lectotype is designated here. Polyblastia brunnensis is synonymized with Thelidium zwackhii. Caloplaca fiumana, lectotypified here, was found to be an older name of the recently described taxon Caloplaca substerilis subsp. orbicularis. Candelariella subdeflexa is replaced by C. blastidiata in the national checklist; Lecanora reagens is excluded from the Czech lichen biota. Twenty nine species are published as new to the Czech Republic: Absconditella rubra, Alyxoria ochrocheila, Aspicilia verrucigera, Blastenia hungarica, Carbonicola anthracophila, Chaenothecopsis montana, C. savonica, Epigloea pleiospora, E. urosperma, Gyalecta ophiospora, Lecanora epibryon, L. flavoleprosa, L. silvae-nigrae, L. stenotropa, Leptorhaphis maggiana, Micarea tomentosa, Myriolecis perpruinosa, Ochrolechia mahluensis, Parmelia serrana, Peltigera ponojensis, Pertusaria borealis, Placynthium caesium, Protoblastenia lilacina, Ramalina europaea, Rinodina trevisanii, Strigula glabra, Verrucaria subcincta, Xanthomendoza huculica and Xylographa soralifera. Including the cited taxa, the lichen biota of the Czech Republic currently comprises 1691 taxa. Key words: Biodiversity, boreal lichens, checklist, lichen-forming fungi, microlichens.
... remains poorly understood. They were described as lichens, "semi-lichens" or non-lichenized parasites of algae or their commensals [3][4][5][6][7]. Lichenicolus records (without the algal film) were very rare. ...
... Almost all of them referred to the lichen parasite -E. urosperma [6][7][8]. E. soleiformis has been reported as a lichenicolous, weakly parasitic fungus only from two localities in Asia [9] and from N Poland [10]. ...
... He suggested that such specimens may represent some separate kind of a phenetic variability within this species and could be regarded under some intraspecific taxonomic level. The variability of the shape of ascospores of E. soleiformis found in different regions of Europe is presented by the following authors: Döbbeler [3] (plate 11,1-3), Ceynowa-Giełdon [4] (Fig. 8c), Pérez-Ortega and Barreno [6] (Fig. 1d). Moreover, Zhurbenko [9] in Russian specimens of E. soleiformis found ascospores which were not exclusively 1-septate but also occasionally simple. ...
Taxonomic remarks, known distribution, ecological notes and new records in Central Europe for two species of Epigloea are provided. Many specimens recognized here under E. soleiformis characterize slightly wider and more ellipsoid ascospores than those described in the protologue but they are regarded as some kind of a phenetic variability of this species. E. soleiformis seems to be not only algicolous fungus but also facultatively lichenicolous on Placynthiella spp. and terricolous Peltigera spp. while E. urosperma is found to be exclusively lichenicolous on Placynthiella dasaea. E. soleiformis is new for the Western Carpathians and the Harz Mts, and E. urosperma is new for whole Carpathians.

Fifty-five new records of lichenicolous fungi from Bolivia are presented. Ten species are new to the Southern Hemisphere: Buelliella lecanorae, Cornutispora pyramidalis, Dactylospora tegularum, Epigloea urosperma, Marchandiobasidium aurantiacum, Monodictys epilepraria, Polycoccum aff. rubellianae, Roselliniella euparmeliicola, Rosellinula frustulosae, Stigmidium eucline and S. gyrophorarum. Seven species are new to South America: Cornutispora lichenicola, C. pittii, Lichenopeltella physciae, L. ramalinae, Lichenostigma rugosa, Minutoexcipula tuckerae and Opegrapha brigantina. Thirty-one species are reported for the first time for Bolivia. Several extensions of the known hosts are reported as well. Three host lichens, Ochrolechia africana, Pertusaria velata and Placynthiella dasaea, are reported as a new to Bolivia.
... Notes − the species was previously known from Europe (Ukraine, Spain, Italy, Austria, Germany, Belgium, The Netherlands, British Isles, Sweden, Norway, Iceland), North America, New Zealand and Subantarctic (Marion Is.), growing on algal films over decomposing bryophytes, but also occasionally over lichens (Cladonia sp., Peltigera aphthosa), humus, rotten wood and even rock (Döbbeler 1984, Purvis et al. 1992, Sérusiaux et al. 1999, Fryday 2000, Berger 2000, Buck & Harris 2002, Santesson et al. 2004, van den Boom 2004, Khodosovtsev 2005, Pérez-Ortega & Barreno 2006. We found it on phyllocladia and stems of Stereocaulon myriocarpum and S. paschale, which are sometimes slightly discoloured under infection. ...
Three new species of lichenicolous fungi are described: Cercidospora ochrolechiae, a widespread pyrenomycete in the Arctic occurring on Ochrolechia and Pertusaria species; Phacopsis oroarcticae, known from Brodoa oroarctica in Severnaya Zemlya; and Polycoccum psorae, known from Anamylopsora pulcherrima in Kirgizstan. Epigloea soleiformis is reported as new to Asia. Conidia with 2-3 septa are documented for the first time for Minutoexcipula; M. tephromelae is reported as new to Asia and the Arctic.
... The genus Epigloea Zukal comprises twelve species worldwide, seven of which were previously recorded from the Iberian Peninsula (Pérez-Ortega & Barreno 2006). Epigloea lives in association with algal films and it is still unclear the specificity of the relationship of the fungus with the algae since it is common to find different algal species below the fungal ascomata. ...
... However it continues to be looked for by lichenologists, although collections of Epigloea are rare because due to its small size and its ephemeral nature it is commonly overlooked. The genus was monographed by Döbbeler (1984) and species occurring in the Iberian Peninsula were treated in Ortega & Barreno (2006). Based on recent collections carried out in different areas of the Iberian Peninsula, I present here new records for three of the species known from the Iberian Peninsula, expanding their distribution ranges southwards. ...

Pérez-Ortega, S. 2009. New records of Epigloea Zukal from Spain. Bot. Complut. 33: 7-8. New records for three species of the algicolous genus Epigloea (Ascomycota) from Spain are given, expanding considerably their distribution range southwards. Some remarks on one specimen of E. cf. medioincrassata found in Sierra de Gredos are made.
Endococcus peltigericola is reported for the first time from North America and Epigloea urosperma for the second time. The detection of interascal filaments in Endococcus peltigericola indicates that it may belong to the genus Polycoccum. Adelococcus immersus and Trematosphaeriopsis parmeliana are newly reported for Russia, the former is also first documented from the Arctic. The description of A. immersus, previously known only from a type specimen, is emended. Halecania alpivaga is reported new to the north-central Siberia growing on an unusual host genus (Dermatocarpon). A key to the species of lichenicolous fungi growing on Dermatocarpon is provided.
Two new species of lichenicolous Opegrapha are described from New Brunswick, Canada. Opegrapha inconspicua was found once on a rock bluff above a river on the thallus of Verrucaria aethiobola. It is characterized by punctiform, rounded, black ascomata 75–170 µm diam., an excipulum dark brown to black only in the upper part and (1–)2(–3)-septate ascospores of (12.5–)15.5–25 × 4–5 (–5.5) µm. Opegrapha parmeliiperda was found in four localities on epiphytic Parmelia squarrosa and P. sulcata. It is characterized by short lirelliform ascomata 70–220(–250) × 70–120 µm, in ± loose groups of 5–15(–20) lirellae forming on black necrotic areas on the host thallus, 4-spored asci of 32–40 × 11–15 µm, and persistently hyaline and 3-septate ascospores of (11–)13–15.5(–17) × (3.5–)4–5(–5.5) µm. Opegrapha lamyi is reported for the first time in Canada, and O. anomea and O. sphaerophoricola for the first time in New Brunswick. One of only two previous reports of O. lamyi for the U.S.A. is based on a specimen from Colorado, revised here to Sclerococcum suburceolatum, the latter record representing a significant range extension for that species. Three of the five lichenicolous Opegrapha species reported here for New Brunswick are so far known in the province only in old mixedwood swamp-forests, highlighting the conservation significance of this forest community type. An identification key to the lichenicolous Opegrapha s.l. species known from Canada is provided. The worldwide diversity and host specificity of lichenicolous Opegrapha s.l. are discussed.
Epigloea diversispora is newly described from a coastal mountain summit in western Oregon, U.S.A. The species has minute, shiny, jet black ascocarps appearing on a biofilm of mixed cyanobacteria and algae. The spores are diverse in both shape and septation. Immature spores are initially nonseptate and ellipsoid, then become soleiform, then 1-septate, while mature spores are 3-septate and short fusiform. Lichenization is uncertain, but the species appears to form a loosely lichenized thallus with hyphae dispersed in a partly cyanobacterial and partly algal crust on thin soil, moss, and plant detritus, over rock.
Crustose lichens and lichenicolous fungi growing on decaying wood were examined from 13 study areas in Finland. Epigloea urosperma is reported as new to Finland and Lecania furfuracea as new to Fennoscandia. In addition, the taxonomy and habitat requirements of six Micarea species are discussed. The species were recently added to the checklist of Finnish lichens based on collections included in this work.
Though most of the lichenicolous fungi belong to the Ascomycetes, their phylogenetic placement based on molecular data is lacking for numerous species. In this study the phylogenetic placement of 19 species of lichenicolous fungi was determined using four loci (LSU rDNA, SSU rDNA, ITS rDNA and mtSSU). The phylogenetic analyses revealed that the studied lichenicolous fungi are widespread across the phylogeny of Lecanoromycetes. One species is placed in Acarosporales, Sarcogyne sphaerospora; five species in Dactylosporaceae, Dactylospora ahtii, D. deminuta, D. glaucoides, D. parasitica and Dactylospora sp.; four species belong to Lecanorales, Lichenosticta alcicorniaria, Epicladonia simplex, E. stenospora and Scutula epiblastematica. The genus Epicladonia is polyphyletic and the type E. sandstedei belongs to Leotiomycetes. Phaeopyxis punctum and Bachmanniomyces uncialicola form a well supported clade in the Ostropomycetidae. Epigloea soleiformis is related to Arthrorhaphis and Anzina. Four species are placed in Ostropales, Corticifraga peltigerae, Cryptodiscus epicladonia, C. galaninae and C. cladoniicola comb. nov. (= Lettauia cladoniicola). Three new species are described, Dactylospora ahtii, Cryptodiscus epicladonia and C. galaninae. © 2017 Naturalis Biodiversity Center & Westerdijk Fungal Biodiversity Institute.
