Echinodiscus lesdainii gen. et comb. nov., a new name for Phacopsis lesdainii Vouaux (lichenicolous Ascomycetes, Leotiales)
Abstract and Figures
The new genus Echinodiscus Etayo & Diederich is introduced to accommodate the lichenicolous ascomycete Phacopsis lesdainii Vouaux, and the new combination E. lesdainii (Vouaux) Etayo & Diederich is proposed. As the holotype has been destroyed, a neotype is selected for this fungus.

... W. v. Brackel & D. Puntillo (hb ivl 7289). — A very rare species, until now known only from a few localities in northern France, Belgium, Scotland, Ireland, Sweden and the U.S.A. (Etayo & Diederich 2000, Kocourková et al. 2010, Diederich et al. 2010b). New to Italy and the Mediterranean. ...
Brackel, W. v. & Puntillo, D. 2016. New records of lichenicolous fungi from Calabria (southern Italy), including a first checklist. — Herzogia 29: 277–306.
Sixty-six sites of lichenological interest were visited during two excursions to Calabria in the years 2014 and 2015. The number of lichenicolous fungi known from this region was enlarged from 37 to 147. New to the Mediterranean are Echinodiscus lesdainii, Nectriopsis cariosae, Tremella cetrariicola and T. everniae, new to Italy are Burgoa angulosa, Cornutispora ciliata, Didymocyrtis consimilis s.lat., Endococcus ramalinarius, Monodictys fuliginosa, Phoma grumantiana, P. melanohaleicola, Pronectria fissuriprodiens, Reconditella physconiarum, Roselliniopsis tartaricola, Sphaerellothecium parietinarium, Stigmidium degelii and Taeniolella punctata. A further 91 species are new to Calabria. The new species Abrothallus puntilloi and Xenonectriella calabrica are described.
... In California it is known from a single collection (Knudsen & Kocourková 2010b. For description see Etayo and Diederich (2000). ...
One hundred and eighty-seven lichenicolous fungi and lichenicolous lichens are reported from California. Abrothallus acetabuli and Intralichen lichenicola are reported new for North America and California. Sclerococcum montagnei is reported new for California. A strict definition of lichenicolous lichens as non-lichenized juvenile parasites that develop an independent lichenized thallus is used and 19 species are reported for California.
... This taxon is new to our checklist. This tiny lichenicolous ascomycete, apparently confined to Lecania species, has been described from northern France near Dunkerque , and has subsequently been reported from the British Isles, Sweden and the U.S.A. (Etayo & Diederich 2000, Kocourková et al. 2010). New to Belgium. ...
Studies of large and mainly recent collections of lichens and lichenicolous fungi led to the addition of 27 taxa to the flora of Belgium, Luxembourg and northern France: Arthonia coronata, A. mediella, Candelaria pacifica, Chaenothecopsis parasitaster, Dacampia cyrtellae, Dactylospora parellaria, Diplotomma epipolium var. parasiticum, Epigloea urosperma, Graphis betulina, Graphium aphthosae (also new to the Netherlands), Lepraria toensbergiana (also new to France), Lichenopeltella maculans (also new to France), Melaspilea bagliettoana, Miriquidica atrofulva, Mycocalicium subtile, Phaeopyxis punctum, Phaeosporobolus chlaroterae (also new to Norway), Placynthium posterulum, Pleospora physciae, Pronectria septemseptata, Sclerophora amabilis, Spiloma auratum, Stigmidium xanthoparmeliarum, Strangospora deplanata, Trapeliopsis wallrothii, Tylophoron hibernicum and Xanthoria ucrainica. 11 additional taxa were reported in recent publications: Buellia saxorum, Cladophialophora cladoniae, Fusicladium peltigericola, Graphis macrocarpa, G. pulverulenta, Laetisaria lichenicola, Lichenoconium aeruginosum, Ochrolechia mahluensis, Phoma ficuzzae, Trimmatostroma quercicola and Verrucaria rhizicola.

Additional notes are given on some rare and threatened macrolichen species. Arthonia digitatae and Placynthium stenophyllum have to be deleted from the checklist. The following new combinations are proposed: Alyxoria culmigena (Lib.) Ertz (basionym Opegrapha culmigena), A. ochrocincta (Werner) Ertz (O. ochrocincta), A. variiformis (Anzi) Ertz (O. variiformis), A. viridipruinosa (B. J. Coppins & R. Yahr) Ertz (O. viridipruinosa), Zwackhia bonplandii (Fée) Ertz (O. bonplandii), Z. circumducta (Nyl.) Ertz (O. circumducta), Z. prosodea (Ach.) Ertz (O. prosodea), Z. robusta (Vain.) Ertz (O. robusta) and Z. sorediifera (P. James) Ertz (O. sorediifera).
... They are very distinct from the known lichenicolous leotialean fungi with excipular hairs, Echinodiscus lesdainii (Etayo & Diederich 2000), Polydesmia lichenis Huhtinen & R. Sant. (Hyaloscyphaceae;Huhtinen & Santesson 1997) and Unguiculariopsis spp. ...
The genus Skyttea is characterized by urceolate ascomata, with a narrow pore when young, a greenish or brownish, rarely reddish exciple of conglutinate hyphae with subglobose to ±cylindrical lumina, bordered near the margin by hyaline to greenish or brownish, usually smooth, straight hairs, the absence of periphyses, rarely branched and apically hardly thickened paraphyses, asci and a hymenium that are entirely I− and KI−, a thin lateral and a very thick apical ascus wall with a small ocular chamber, and normally aseptate ascospores. It is considered to belong to the Leotiales and not to the Ostropales. It comprises at least 17 species, including S. caesii sp. nov., S. carboneae sp. nov., S. lecanorae sp. nov., S. mayrhoferi sp. nov., S. pyrenulae sp. nov., S. radiatilis comb. nov., S. tavaresae sp. nov. and S. thelotrematis sp. nov. Rhymbocarpus is shown to be a distinct leotialean genus, distinguished from Llimoniella by a different excipular structure, different pigments and the presence of excipular hairs, which, in some species, are embedded in the excipular gel and thus not visible macroscopically. In addition to the type species, R. geographici, of which a neotype is designated, it includes R. boomii sp. nov., R. cruciatus comb. nov., R. fuscoatrae comb. nov., R. makarovae sp. nov., R. neglectus comb. nov.,R. pertusariae sp. nov., R. pubescens comb. nov. and R. stereocaulorum comb. nov. Llimoniella s. str. comprises at least 6 species, including the type, L. scabridula, L. adnata, L. pertusariae sp. nov., L. pyrenulae sp. nov., L. ramalinae comb. nov. and L. vinosa comb. nov. Several species formerly assigned to Skyttea or Llimoniella are now included in the leotialean genus Unguiculariopsis, and the following new combinations are proposed: Unguiculariopsis acrocordiae comb. nov., U. groenlandiae comb. nov. andU. lesdainii comb. nov. A lectotype is chosen for Lichen stictoceros, which is shown to be a synonym ofEvernia prunastri . Keys are given for the species of Skyttea, Llimoniella and Rhymbocarpus, and for the lichenicolous genera of Leotiales and Ostropales.
The genus Lethariicola is shown to be a synonym of Odontotrema. Fifteen lichenicolous species are recognized: O. bryoriae sp. three undescribed species on Lecanora, Mycoblastus and Usnea. The type of O. cuculare has two distinct lichenicolous species of Odontotrema, and the name is lectotypified on the species growing on Parmeliopsis. A key is given to all lichenicolous species of Odontotrema and Paralethariicola.
An annotated key to the lichenicolous (lichen-inhabiting) Ascomycota, including mitosporic morphs, known from Sweden is presented. Recent additions, both from the literature and our own collections, of these fungi to the Swedish flora are also included. A total of 298 ascomycetes representing 83 genera, and 65 mitosporic fungi from 31 genera, have been found to occur in Sweden. Each species keyed out is followed by information and selected literature references on morphology, distribution, and ecology. Taxonomic notes and discussions are given for several critical genera and species, and selected species are illustrated.

Twenty-eight species are new to Russia, 15 new to the Arctic, five new to Mongolia and nine new to Alaska. Twenty lichen genera and 31 species are new hosts for various species of lichenicolous fungi.
Gyalideopsis floridae, a lichenicolous lichen growing on Parmotrema in Florida (U.S.A.) is described as new. It is distinguished from all hitherto known species of the genus by multispored asci and simple ascospores.
The genus Lethariicola is shown to be a synonym of Odontotrema. Fifteen lichenicolous species are recognized: O. bryoriae sp. nov. (on Bryoria), O. cuculare comb. nov. (on Parmeliopsis hyperopta), O. figulinum comb. nov. (on Lecanora polytropa) O. intermedium sp. nov. (on Thamnolia), O. lecanorae sp. nov. (on Lecanora), O. melaneliae sp. nov. (on Melanelia), O. ochrolechiae sp. nov. (on Ochrolechia), O. pertusariae sp. nov. (on Pertusaria hymenea), O. rhizocarpicola sp. nov. (on Rhizocarpon) O. santessonii sp. nov. (on Thamnolia), O. sipei comb. nov. (on Letharia), O. thamnoliae sp. nov. (on Thamnolia), and three undescribed species on Lecanora, Mycoblastus and Usnea. The type of O. cuculare has two distinct lichenicolous species of Odontotrema, and the name is lectotypified on the species growing on Parmeliopsis. A key is given to all lichenicolous species of Odontotrema and Paralethariicola.
Since the last compilation in 1983, the number of lichenicolous fungi (and lichenicolous lichens) recorded in Great Britain and Ireland has increased from 218 to 403 species (a rise of 85%). The introduction includes accounts of: the history of investigation, circumscription, phylogenetic relationships, symbiotic interactions, dispersal and establishment, distribution, culture, host restriction, and identification. The checklist enumerates the recorded species. Information is provided on the systematic position of each genus, together with the authors and dates of publication of all accepted names; synonyms used in the literature of the two countries since 1910 are cross-indexed. References to pertinent literature with descriptions and discussions are included, together with notes on particular species. The list of references cited includes 298 publications. The following new scientific names are introduced: Diederichia gen. nov., and Dactylospora scapanaria (syn. Lecidea scapanaria), Diederichia pseudevemiae (syn. Macrophomina pseudeverniae), Muellerella ventosicola (syn. Microthelia ventosicola) and Nigromacula uniseptata (syn. Vouauxiella uniseptata) combs, nov.
Phacopsis is a genus of lichenicolous fungi distributed worldwide on members of the Parmeliaceae s, ampl. The genus is characterized using current concepts, and its delimitation and family position are discussed. Thirteen taxa are accepted and a key supplied together with new data on their host specificity and distribution. In this genus ascospore shape as well as color and amyloidity of the hypothecial hyphae proved to be major diagnostic characters. Phacopsis falcispora Triebel di Rambold, P. falcispora var. sipmanii Diederich and Triebel, P. lethariellae Hafellner & Rambold, P. menegazziae Triebel & Rambold, P. oxyspora var. defecta Triebel and Rambold, and P. oxyspora var. fusca Triebel and Rambold are described as new. Phacopsis oxyspora (Tul.) Triebel and Rambold and P. vulpina Tul. are lectotypified. Emended descriptions of P. oxyspora var. oxyspora, P. prolificans (Mull. Arg.) Triebel & Rambold, and P. rufa (Mull. Arg.) Triebel di Rambold and notes on other species of the genus are given.
