Sculptolumina conradiae is different from the other four species because it forms 1-or 3-septate ascospores which have markedly thickened lateral and septal inner walls (resulting in four approximately rounded lumina) and by the lack of typical lichen substances (Giralt et al. 2014). ...
Sculptolumina yunnanensis, a saxicolous lichenized fungus in the family Caliciaceae, is described as new from Yunnan, China. Its morphological characters include: ocher and epilithic thalli, pseudolecanorine or lecideine and sessile apothecia, flat and epruinose apothecial discs, Mischoblastia- type ascospores with funnel-shaped cell lumina and filiform conidia. This is the second saxicolous species in the genus Sculptolumina. A molecular phylogenetic analysis was performed for Sculptolumina, including S. japonica and S. yunnanensis, for the first time. A multilocus phylogeny of Buellia s.l. revealed that Sculptolumina forms a monophyletic clade with high support, and S. japonica and S. yunnanensis have a sister relationship within this clade.
... Although commonly keyed out as being parasitic on other lichens (e.g. Elix et al. 2017), in my experience, this species occurs mostly independently and is characterised by a brown or brownish grey, squamulose thallus lacking lichen substances, black apothecia with a carbonised excipulum, Lecanora-type asci and relatively small, Buellia-type ascospores, 9-15 × 5-8 µm, and bacilliform conidia, 3-5 × 0.5-1.5 µm (Elix 2015 On bleached eucalypt wood. This species is nonlichenised but it is frequently included in lichen checklists on account of its close ecological relationship and morphological similarity to lichenised calicioid genera such as Calicium and Chaenotheca. ...
A ten-year study of the lichens of Kangaroo Island, South Australia, based on extensive fieldwork and a review of more than 1500 herbarium specimens, revealed a remarkable flora of 366 taxa. Fourteen appear to be restricted to the island, although they could be expected to occur on the southern Australian mainland, which is most similar to Kangaroo Island with respect to floristics and ecology, and where similar habitats can be found. In the course of the project, many species were recorded for South Australia for the first time, and a further 95 are reported here, including 19 that are first records for Australia as a whole. The most noteworthy of these include Aspicilia praecrenata (Nyl.) Hue, Catillaria nigroclavata (Nyl.) Schuler, Clauzadea metzleri Clauzade & Cl.Roux ex D.Hawksw., Halecania spodomela (Nyl.) M.Mayrhofer, Lecania koerberiana Lahm, Metamelanea melambola (Tuck.) Henssen, Schismatomma rediunta (Hasse) Tehler and Strangospora pinicola (A.Massal.) Körb., all previously known only from the Northern Hemisphere. The history of lichen investigations on the island, from the visit by Matthew Flinders in 1802 up to the present, is reviewed briefly. For the lichen study, the island's vegetation was classified into the following major habitat types: mallee woodland, Melaleuca-dominated swampy woodland, Callitris-dominated coniferous woodland, Eucalyptus-dominated dry sclerophyll forest, Allocasuarina woodland, the littoral zone, agricultural land, consolidated calcareous soil communities, and semi-inundated rocks in freshwater streams.

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.
Five lichen species (Ascomycota) are described as new from rocks in coastal and tableland localities of southern New South Wales: Catillaria gerroana P.M.McCarthy & Elix (Catillariaceae), Fellhanera robusta P.M.McCarthy & Elix (Pilocarpaceae), Menegazzia fortuita Elix & P.M.McCarthy (Parmeliaceae), Ramboldia curvispora P.M.McCarthy & Elix (Lecanoraceae) and Sarcogyne maritima P.M.McCarthy & Elix (Acarosporaceae). Arthonia lapidicola (Taylor) Branth & Rostrup (Arthoniaceae) is reported for the first time from Australia
An eight-year study of the lichens of Kangaroo Island, based on extensive field work and a review of herbarium records, has revealed a diverse flora of more than 350 species. Of these, 24, including 15 that are endemic to the island, have been described as new to science. Many other species are new records for South Australia, Australia or the Southern Hemisphere. Most species recorded are shared with mainland southern Australia, and/or with Tasmania and its offshore islands. A large number are uncommon on Kangaroo Island and restricted to highly specialised habitats. Land clearing, fire and other disturbances have fragmented some vegetation types and reduced the lichen flora drastically. Hence rocks, isolated trees and small wooded copses provide important but highly fragile lichen refugia in an otherwise severely modified landscape. Melaleuca-dominated swampy woodland, Callitris-dominated woodland, mallee woodland and calcareous soil communities are discussed briefly as examples where fragmentation has been particularly severe. The rare and locally endangered Pseudocyphellaria aurata (Ach.) Vain. and the seemingly extinct Cladia ferdinandii (Müll.Arg.) Filson are two examples of the depletion of the lichen flora.
