Sarcoscypha is a genus of ascomycete fungus and a type genus of the family Sarcoscyphaceae. Species of Sarcoscypha are present in Europe, North America and tropical Asia. They are characterised by a cup-shaped apothecium which is often brightly coloured. They have had a range of popular uses, one of which was as a table decoration. Some members of the family such as S. coccinea and the - according to new knowledge - more common S. austriaca in western Europe and United States have bright scarlet apothecia which have given them familiar names such as the scarlet cup fungus and scarlet elf cap.
The Pertusariales are an order of fungi in the class Lecanoromycetes, comprising 8 families, 31 genera, and over 600 species, many of which form lichens. This diverse group is characterized by complex taxonomic history and ongoing phylogenetic revisions. Originally proposed by Maurice Choisy in 1949 and later formally published by the lichenologists David L. Hawksworth and Ove Eriksson in 1986, Pertusariales has undergone significant reclassification due to molecular phylogenetics studies. The order includes well-known genera such as Pertusaria and Ochrolechia, as well as families like Megasporaceae and Icmadophilaceae.
The Gomphillaceae are a family of lichen-forming fungi in the order Graphidales. Species in this family are found mostly in tropical regions.
Helminthocarpon is a fungal genus of uncertain familial placement in the order Arthoniales. It comprises the single species Helminthocarpon leprevostii, a crustose lichen. This species, which is widespread in tropical regions of the world, is typically found growing on tree bark, and occasionally on wood.
Thelenellaceae is a family of lichen-forming fungi. It is the sole family in the monotypic order Thelenellales, and contains three genera and about 50 species.
The Pyrenotrichaceae are a small family of fungi in the order Chaetothyriales. It contains two genera, and a total of six species. The genus Pyrenothrix has two species of bark- or leaf-dwelling lichens, while Neophaeococcomyces has four species of saprobic fungi.
Amerosporiopsis phaeographidis is a species of lichenicolous fungus in the subphylum Pezizomycotina. It grows as black spots on the lichen Phaeographis brasiliensis, from which it gets its name. It has only been found in one place in the Fakahatchee Strand Preserve State Park in Florida in the United States. Molecular phylogenetics testing might reveal that this is actually a new genus, but it is morphologically similar to the one other species in Amerosporiopsis, except that it has wider conidia, has no conidiophores, and lives in a different habitat.
Quadracaea is a fungal genus in the division Ascomycota. The relationship of this taxon to other taxa within the division is unknown, and it has not yet been placed with certainty into any class, order, or family. The genus contains three species of hyphomycetes. Quadracea is characterised by its distinctive spore-producing structures and the unique appearance and morphology of its spores.
Quadracaea roureae is a species of fungus in the division Ascomycota. The fungus has specialised cells that produce multiple spores, flask-shaped cells that release spores by breaking open, and a unique way of shedding its spores. The type specimen of this hyphomycetes fungus was found growing on dead branches of Rourea minor in Hainan Bawangling National Nature Reserve. At the time of its original publication, it was only known to occur at the type locality in China.
Quadracaea stauroconidia is a species of fungus in the division Ascomycota. This hyphomycetes fungus was formally described as a new species in 2013. The type specimen was collected by the authors from Serra da Jibóiapt,, where it was found growing on submerged leaves. The species epithet, stauroconidia, makes reference to the star-shaped conidia.
Sclerococcum toensbergii is a species of lichenicolous (lichen-dwelling) fungus in the family Sclerococcaceae. It is known from only a couple of collections made in the northwestern United States, and a collection in France. In the United States, it has been recorded on the bark-dwelling lichens Megalaria pulverea and Pertusaria carneopallida, while in France, it was found growing on Caloplaca cerina.
Puttea is a genus of lichen-forming fungi with uncertain familial placement in the order Lecanorales. The genus comprises four species. Finnish lichenologists Soili Stenroos and Seppo Huhtinen established the genus Puttea in 2009 for the lichen species formerly known as Lecidea margaritella, which has undergone various reclassifications. Molecular phylogenetics analyses have shown that Puttea margaritella does not align closely with genera like Fellhanera or Micarea, but its precise familial placement remains uncertain. Puttea is characterized by an indistinct, lichenized thallus composed of delicate fungal filaments and small algal cells. Its minute, round, whitish apothecia lack a distinct margin, and the asci, or spore-producing cells, are thick-walled, club-shaped, and contain eight spores, showing specific reactions with iodine-based stains. The type species of the genus, Puttea margaritella, typically inhabits boreal forests, growing on the liverwort species Ptilidium pulcherrimum and sometimes on decaying wood or bark. Initially thought to be confined to Europe, it has since been found in North America, particularly in Alaska and Québec, extending its known range. The species is parasitic, damaging its host, and is considered rare within its distribution.
Thelenella lateralis is a species of corticolous (bark-dwelling), crustose lichen in the family Thelenellaceae. This species is notable for its eccentric ostiole and irregularly muriform ascospores, which are 7–9 by 0–2-septate and measure 27–32 μm by 9–10.5 μm.
Ramboldia gowardiana is a species of corticolous (bark-dwelling), crustose lichen in the family Ramboldiaceae. First discovered in 2003 in Montana, United States, it typically appears as a grayish or greenish crust on tree bark, particularly on conifers like pines and firs. The lichen is characterised by its small, bright red to orange-red reproductive structures (apothecia) visible on its surface. R. gowardiana is found in dry, temperate forests from Alaska to California, often at elevations between 300 and 1,400 meters. Initially classified in a different genus, it was reclassified as Ramboldia in 2008 based on genetic studies. This lichen is part of the biodiversity of the Pacific Northwest region of North America.
Psammina is a fungal genus in the division Ascomycota. The relationship of this taxon to other taxa within the division is unknown, and it has not yet been placed with certainty into any class, order, or family. The genus comprises fungi that inhabit various environments, growing on plants, algae, and lichens. These fungi are notable for their unique reproductive structures, which resemble tiny hands or palms when viewed under a microscope. Psammina species play diverse ecological roles: some form partnerships with algae to create lichens, others grow on existing lichens, and some can cause damage to their host organisms. The genus was first proposed in 1890 and currently includes ten recognised species. While Psammina fungi have been found mainly in Europe, with sightings in countries such as the United Kingdom, the Netherlands, and France, at least one species has been reported in Brazil, suggesting a potentially wider distribution.
Megaloblastenia is a genus of crustose lichen-forming fungi in the family Megalosporaceae, comprising three species. Proposed by Dutch lichenologist Harrie Sipman in 1983, the genus is characterised by its thick, ecorticate thallus ranging from pale whitish-grey to yellowish, and its disc-like fruiting bodies (apothecia) that can be biatorine or lecideine. Megaloblastenia lichens form a symbiotic relationship with Dictyochloropsis algae, produce hyaline, bicellular ascospores with polaribilocular structure, and contain chemical compounds such as zeorin, pannarin, or usnic acid. Found in Australasia and South America, these lichens typically grow as epiphytes on trees in moist forests within temperate to tropical oceanic climates.
Pyrenothrix is a small genus of lichen-forming fungi in the family Pyrenotrichaceae. It comprises two species of filamentous lichens, which are organisms formed by a symbiotic relationship between fungi and photosynthetic partners. The genus is characterized by its unique structure, featuring densely arranged filaments composed of cyanobacteria wrapped in fungal threads. Pyrenothrix species form dark greyish-brown growths on various surfaces, with one species found on tree bark and the other on leaves in tropical forests. The genus was circumscribed in 1917 by American scientist Lincoln Ware Riddle, based on specimens collected in Florida. Pyrenothrix is distinguished from other lichens by its intricate cellular structure and reproductive features, including specialized spore-producing structures.
Paracollema is a small genus of lichen-forming fungi in the family Collemataceae. It comprises two species of jelly lichens, characterised by their small size, gelatinous nature when wet, and distinctive reproductive structures. The genus was proposed in 2013 and later validated in 2017. Paracollema lichens form small, leafy thalli up to 1 cm in diameter, with dark olive green to brownish colouration. They are distinguished from related genera by their very small asci and spores. Both known species are primarily epiphytic and have a limited distribution in southern Europe and northern Africa, typically found in Mediterranean or semi-arid climates.
Arthonia radiata, the asterisk lichen, is a common and widepspread species of corticolous (bark-dwelling), crustose lichen in the family Arthoniaceae.
Usnocetraria oakesiana, commonly known as the yellow ribbon lichen, or the yellow-green ribbon lichen, is a species of corticolous (bark-dwelling), foliose lichen in the family Parmeliaceae. It occurs in Asia, Europe, the north-eastern United States, and eastern Canada.
