An ascocarp, or ascoma, is the fruiting body (sporocarp) of an ascomycete phylum fungus. It consists of very tightly interwoven hyphae and millions of embedded asci, each of which typically contains four to eight ascospores. Ascocarps are most commonly bowl-shaped (apothecia) but may take on a spherical or flask-like form that has a pore opening to release spores (perithecia) or no opening (cleistothecia).
Abrothallus is a genus of lichenicolous fungi. It is the only genus in the monotypic family Abrothallaceae, which itself is the sole taxon in the order Abrothallales.
Architrypethelium is a genus of lichen-forming fungi in the family Trypetheliaceae.
Phacopsis is a genus of lichenicolous (lichen-dwelling) fungi. They are parasites of members of the large lichen family Parmeliaceae, of which they are also a member. Originally proposed by Edmond Tulasne in 1852 to contain 3 species, Phacopsis now contains 10 species, although historically, 33 taxa have been described in the genus. Many of the species are poorly known, some of them having been documented only from the type specimen.
Cercophora areolata is a member of the Ascomycota division, and is grouped into the Lasiosphaeriaceae family based on morphology. C. areolata is a coprophilous fungus that has been most recently isolated from porcupine dung. Defining features of C. areolata include: 1) ovoid-conical, glabrous ascomata, 2) black, carbonaceous, areolate peridium and 3) clavate-shaped, single-walled asci. From studies on C. areolata, this fungus produces multiple antifungal compounds, which inhibit other competitor fungi.
Lecanographaceae is a family of mostly lichens in the order Arthoniales. The family was circumscribed in 2014, prompted by a molecular phylogenetic-based restructuring of the Arthoniales.
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.
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.
Phylloblastia is a genus of foliicolous (leaf-dwelling) lichens in the family Verrucariaceae. The genus was circumscribed in 1921 by Finnish lichenologist Edvard August Vainio, with Phylloblastia dolichospora assigned as the type species.
Halospora is a genus of lichenicolous (lichen-dwelling) fungi in the family Verrucariaceae. Species in the genus parasitise calcicolous crustose lichens, i.e., those that prefer lime-rich substrates.
Mastodia is a genus of lichen-forming fungi in the family Verrucariaceae. It has six species.
Lichenoverruculina is a fungal genus in the family Hyponectriaceae and order Amphisphaeriales. This is a monotypic genus, containing the single species Lichenoverruculina sigmatospora. which was published in Herzogia vol.24 (2) on page 274 in 2011.
Ostropomyces is a genus of fungi in the family Stictidaceae. It has two species, both of which are found in tropical forests in northern Thailand, where they grow as saprotrophs on bark.
Astrothelium chulumanense is a little-known species of corticolous (bark-dwelling), crustose lichen in the family Trypetheliaceae. Found in the Yungas montane forest of Bolivia, it was formally described as a new species in 2023. It is characterized by pseudostromata not differing in colour from the thallus, perithecia immersed for the most part in the thallus with the upper part elevated above and covered with orange pigment, apical and fused ostioles, the absence of lichexanthone, a clear hamathecium, eight-spored asci, and large, muriform ascospores with a thickened median septum.
Pisorisporium is a genus of freshwater and terrestrial fungi in the family Pisorisporiaceae and Order of Pisorisporiales and in the subclass of Pisorisporiomycetidae.
Protothelenella is a genus of fungi in the family Protothelenellaceae. It contains 11 species, some of which form lichens. Protothelenella species have a crustose thallus with spherical to pear-shaped, dark brown to blackish perithecia. Microscopic characteristics of the genus include bitunicate asci with an amyloid tholus, and ascospores that are colourless and contain multiple internal partitions. Some species grow on acidic substrates including rocks, soil, bryophytes, plant detritus or rotten wood. Other species are lichenicolous (lichen-dwelling), growing on species of Solorina, Peltigera, Pseudocyphellaria, or Cladonia.
Aspiciliopsis is a genus of lichen-forming fungi in the family Trapeliaceae. It has two species, both of which occur in the Southern Hemisphere.
Polycoccaceae is a family of lichenicolous (lichen-dwelling) fungi in the order Trypetheliales. The family was circumscribed in 2015 by Damien Ertz, Josef Hafellner, and Paul Diederich. Molecular phylogenetic analysis shows Polycoccaceae to have a sister relationship with the family Trypetheliaceae.
Macroconstrictolumina is a genus of lichen-forming fungi in the family Trypetheliaceae. It has four 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.
