Capronia cogtii is a rare species of lichenicolous (lichen-dwelling) fungus in the family Herpotrichiellaceae. [1] Found in northern Mongolia, it was described as a new species in 2019.
Capronia cogtii belongs to the fungal family Herpotrichiellaceae and is characterized by its hyaline ascospores, which distinguish it from most other Capronia species that have pigmented ascospores. The new species is most similar to C. amylacea , C. hypotrachynae , C. normandinae , and C. pseudonormandinae , but can be distinguished by its smaller ascomata, longer hyaline ascospores, and different host genus, Vahliella (Vahliellaceae), compared to Peltigera (Peltigeraceae). The species epithet cogtii was given in honor of the late Professor Ulzii Cogt, who was a prominent figure in Mongolian lichenology. [2]
The vegetative hyphae of Capronia cogtii are pale brown, 2–3.5 μm wide, septate, and ramify from the lower parts of the exciple . The ascomata are perithecial , blackish, more or less glossy, roughly spherical to ovoid, and occasionally shortly papillate at the apex. They are setose above, ostiolate, 90–150 μm in diameter, and have a rough surface. The setae are dark brown, straight, not branched, 15–60 μm tall, 4–5 μm wide at base, and arise from a discrete dark foot-cell. The exciple is made of medium to dark brown pseudoparenchymatous cells outwardly, and somewhat hyaline, strongly elongated, radially compressed cells inwardly. The periphyses are hyaline, measure 10–20 by 2–3 μm, septate, and are not branched. The ascospores are hyaline, clavate to very narrowly obovoid , and typically have 3 transverse septa (sometimes as few as 1 or as many or 5). They are usually constricted at the septa, smooth-walled, and overlappingly crowded in the ascus. [2]
Capronia cogtii is known only from the holotype, which was collected on the thallus of Vahliella leucophaea and occasionally on adjacent decaying mosses in sparse Larix sibirica mountain forest in northern Mongolia. The host lichen, Vahliella leucophaea, is morphologically similar to some species of Pannariaceae and has long been placed in this family. This is the first species of Capronia known to grow on members of Vahliellaceae. Two Capronia species are known to grow on Pannariaceae hosts, C. magellanica , growing on species of Fuscopannaria , and C. paranectrioides , growing on species of Erioderma . Capronia cogtii is also similar to C. andina and C. solitaria but can be distinguished by its hyaline ascospores and larger ascomata, respectively. [2]
The Loramycetaceae are a family of fungi in the Ascomycota, class Leotiomycetes. This is a monotypic taxon, containing the single genus Loramyces; the genus contains two aquatic species, L. juncicola, named by American mycologist William H. Weston in 1929, and L. macrosporus, first described by C.T. Ingold and B. Chapman in 1952.
Keissleriella rara is a rare species of fungus in the family Lophiostomataceae. The species fruits exclusively on dead or dying standing culms of the saltmarsh plant Juncus roemerianus. It is known only from the Atlantic Coast of North Carolina.
Massarina carolinensis is a species of fungus in the Lophiostomataceae family. The species is found exclusively on the lower parts of the culms of the saltmarsh Juncus roemerianus on the Atlantic Coast of North Carolina.
Paraphaeosphaeria pilleata is a species of fungus in the Lophiostomataceae family. The species fruits exclusively in the lower parts of the culms of the black needlerush. It is found on the Atlantic Coast of North Carolina.
Botryotrichum piluliferum is a fungal species first identified in 1885 by Saccardo and Marchal. It was discovered to be the asexual state of a member of the ascomycete genus, Chaetomium. The name B. piluliferum now applies to the fungus in all its states. B. piluliferum has been found worldwide in a wide range of habitats such as animal dung and vegetation. The colonies of this fungus start off white and grow rapidly to a brown colour. The conidia are smooth and white. B. piluliferum grows optimally at a temperature of 25-30 °C and a pH of 5.5.
Capronia mansonii is a mesophilic black yeast that is a part of the Herpotrichiellaceae. The species is uncommon in nature but is saprotrophic in nature and been discovered on decaying plant matter, particularly wood. This fungus is naturally found in the Netherlands and has successfully been cultured in lab. It is a teleomorph of the ascomycota division and possesses brown spores.
Hydropunctaria is a genus of saxicolous (rock-dwelling), crustose lichens in the family Verrucariaceae. The genus includes both aquatic and amphibious species, with members that colonise either marine or freshwater habitats. The type species, Hydropunctaria maura, was formerly classified in the large genus Verrucaria. It is a widely distributed species common to littoral zones. Including the type species, five Hydropunctaria lichens are considered marine species: H. adriatica, H. amphibia, H. aractina, H. orae, and H. oceanica.
Atrophysma is a fungal genus in the family Pannariaceae. It contains the single species Atrophysma cyanomelanos, a crustose lichen found only in Alaska.
Rhizocarpales are an order of lichen-forming fungi in the subclass Lecanoromycetidae of the class Lecanoromycetes. It has two families, Rhizocarpaceae and Sporastatiaceae, which contain mostly crustose lichens.
Opegrapha vulpina is a species of lichenicolous (lichen-eating) fungus in the family Opegraphaceae. It is found in the Czech Republic, Dobruja, Romania, and the Italian Apennine Mountains. It grows parasitically on two species of saxicolous (rock-dwelling), crustose lichens.
Zwackhiomyces polischukii is a species of lichenicolous (lichen-eating) fungus in the family Xanthopyreniaceae. It occurs in Ukraine, where it parasitises the crustose lichens Bacidia fraxinea and B. rubella.
Clypeococcum bisporum is a species of lichenicolous (lichen-eating) fungus in the family Polycoccaceae. It is found in the Russian Far East, in Mongolia, and from northwest Alaska, where it grows parasitically on lichens from the genera Cetraria and Flavocetraria.

The new species is characterized by 50–120 µm wide ascomata, 40–95 µm long setae, (1–)3-septate, pale brown, 11.9–15.7 × 4.4–5.8 µm ascospores, and an I+ red hymenium.
