The Pyrenulaceae are a family of mostly lichen-forming fungi in the order Pyrenulales, though a few members are secondarily non-lichenized. They form thin crusts on bark and, less often, on rock, and partner with species from the green algal genus Trentepohlia. The family is characterized by flask-shaped fruiting bodies (perithecia) that typically open through a pore, and by ascospores whose internal walls form distinctive rounded to diamond-shaped chambers. The number of accepted genera varies among sources—recent phylogenetic treatments have sampled about 13, while broader taxonomic

Lecanora muralis (Protoparmeliopsis muralis) is a waxy-looking, pale yellowish-green crustose lichen that usually grows in rosettes radiating from a center (placodioid) filled with disc-like yellowish-tan fruiting bodies (apothecia). It grows all over the world. It is extremely variable in its characteristics as a single taxon, and may represent a complex of species. The fruiting body parts have rims of tissue similar to that of the main nonfruiting body (thallus), which is called lecanorine. It is paler and greener than L. mellea, and more yellow than L. sierrae. In California, it may be the

Aleurodiscus is a genus of corticioid fungi in the family Stereaceae.

Cosmospora is a genus of ascomycete fungi in the family Nectriaceae. The genus, as circumscribed by Rossman et al. (1998), included all the nectrioid species with small, reddish, non-ornamented sexual fruiting bodies that collapse laterally when dry. However, the genus was shown to be polyphyletic, and the majority of species were re-classified into revived or recently established genera that are monophyletic. Cosmospora sensu Rossman housed members of the following genera: Chaetopsina, Cylindrocladiella, Fusicolla, Macroconia, Mariannaea, Microcera, Pseudocosmospora, Stylonectria, and

Urocystis occulta is a smut fungus which attacks the leaves and stalks of rye (Secale cereale). It is found in Australia, Europe, and North America. The fungus was first described by German botanist Karl Friedrich Wilhelm Wallroth under the name Erysiphe occulta in 1833, before being renamed as Urocystis occulta in 1857 by German botanist and mycologist Gottlob Ludwig Rabenhorst.

Lecanora polytropa, the granite-speck rim lichen, is a species of saxicolous (rock-dwelling), crustose lichen in the family Lecanoraceae. A small, inconspicuous species that grows in the cracks of rock surfaces, it has a cosmopolitan distribution and has been recorded on all continents, including Antarctica.

Coleroa is a genus of fungi belonging to the family Venturiaceae. The species of this genus are found in Eurasia and Northern America.

Helotiales is an order of the class Leotiomycetes within the division Ascomycota. The taxonomy within Helotiales has been debated. It has expanded significantly as genomic techniques for taxonomical identification have become more commonly used. As of February 2020, the order is estimated to contain 30 accepted families, 519 genera, and 6266 species. Helotiales is the largest order of non-stromatic discomycetes that usually, but not always, have brightly coloured apothecia. Many members of the family have obviously cup-shaped ascomata with little or no stipes. They are usually found fruiting

Rhizocarpon alpicola is a species of saxicolous (rock-dwelling), crustose lichen in the family Rhizocarpaceae. The lichen grows as a patch-like crust up to 15 cm across, composed of small yellowish-green tiles that develop black, button-like reproductive structures. A member of the Rhizocarpon geographicum species complex, R. alpicola can usually be distinguished from related species by its large and smooth areoles. R. alpicola is often utilised in lichenometry, a dating technique used to estimate the length of exposure of rock surfaces. Research on Norwegian glacier forelands has shown that

Clathrospora is a genus of fungi in the family Diademaceae. The widespread genus contained five species in 2008, the genus increased to 20 species by 2023.

Ascochyta caricae is a fungal plant pathogen that causes dry rot on papaya.

Zopfia rhizophila is a plant pathogen that causes Zopfia root rot in asparagus.

Zopfia is a genus of fungi in the family Zopfiaceae. The widespread genus contained 5 species, until another species was accepted. The genus was circumscribed by Gottlob Ludwig Rabenhorst in Fungi europ. exsicc. no. 1734. in 1874. The genus name of Zopfia is in honour of Friedrich (or Friederich) Wilhelm Zopf (1846–1909), who was a well-known German botanist and mycologist. He dedicated to his whole life with fungal biology, particularly in classification of fungi and dye production in fungi and lichens.

Leptospora is a genus of fungi in the class Dothideomycetes. It was placed in the Phaeosphaeriaceae family. The genus was circumscribed by German botanist and mycologist Gottlob Ludwig Rabenhorst in 1908, with Leptospora rubella assigned as the type species in Hedwigia vol.1 on page 116 in 1857. It had previously been Sphaeria rubella Pers., Syn. meth. fung. (Göttingen) 1: 63 (1801).
