Lecidea atrobrunnea is a crustose lichen in the Lecideaceae family, found in mountains of the continental western United States and Alaska. With other lichen communities, it forms dark vertical drip-like stripings along drainage tracks in the rock faces, resulting in Native Americans giving the name "Face of a Young Woman Stained with Tears" to Half Dome. This combined lichen community appears black from a distance, but brown up close.
Lecanora polytropa, commonly known as the granite-speck rim lichen, is a species of saxicolous lichen in the family Parmeliaceae. 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.
Lichenostigma cosmopolites is a species of lichenicolous fungus belonging to the family Phaeococcomycetaceae. It was described as new to science in 1999 by lichenologists Josef Hafellner and Vicent Calatayud. The fungus grows parasitically on Xanthoparmelia lichens. In India it has been reported from the thallus of Xanthoparmelia stenophylla.
Muellerella lichenicola is a species of lichenicolous fungus in the family Verrucariaceae. It was first formally described as a new species in 1826 by Søren Christian Sommerfelt, as Sphaeria lichenicola. David Leslie Hawksworth transferred it to the genus Muellerella in 1979.
Muellerella ventosicola is a species of lichenicolous fungus in the family Verrucariaceae. It shows preference to growing on species of the genus Rhizocarpon but can also associate with other genera.
Lichenopeltella uncialicola is a species of fungus belonging to the class Dothideomycetes. The species was discovered in Iceland in 2010 where it was found growing on Cladonia uncialis. Since then, it has been found on a different host species, Cladonia rangiferina, in North-Korea, Italy Austria, and Greenland.
Muellerella pygmaea is a species of lichenicolous fungus in the family Verrucariaceae. It has a cosmopolitan distribution in Arctic-alpine areas and grows on the thallus and apothecia of a number of hosts.
Xenonectriella subimperspicua is a species of lichenicolous fungus in the family Nectriaceae. It has been recorded from South America, Europe, and New Zealand.
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.
Muellerella hospitans is a species of lichenicolous fungus in the family Verrucariaceae. It is known to infect the lichen Bacidia rubella.
Bacidia rubella is a species of lichen in the family Ramalinaceae.
Cercidospora macrospora is a species of lichenicolous fungus in the genus Cercidospora but it has not been assigned to a family. It is known from the northern hemisphere.
Muellerella erratica is a species of lichenicolous fungus in the family Verrucariaceae. It has been reported from numerous countries, including India. Known host species include the thallus of Lecidea lapicida and Lecanora.
Xanthoparmelia stenophylla is a species of foliose lichen in the family Parmeliaceae.
Physcia aipolia is a species of lichen in the family Physciaceae. It has a worldwide distribution.
Rhizocarpon furax is a species of lichen in the family Rhizocarpaceae. It is found in Europe, where it has a scattered distribution.
Capronia suijae is a species of lichenicolous fungus in the family Herpotrichiellaceae. Found in Belarus, it was formally described as a new species in 2017 by Andrei Tsurykau and Javier Etayo. The type specimen was collected from Ostrozhanka Village where it was found growing on the thallus of the bark-dwelling, crustose lichen Xanthoria parietina; Muellerella lichenicola was also simultaneously parasitizing the lichen. Capronia suijae is only known to occur at the type locality. The species epithet suijae honours Estonian lichenologist Ave Suija, "in recognition of her important contribution to the knowledge of lichenicolous fungi".
