Didymocyrtis trassii is a species of lichenicolous (lichen-eating) fungus in the family Phaeosphaeriaceae. It is found in southern Ukraine, where it parasitises the foliose lichen Cetraria aculeata growing on sand dunes.
The fungus was formally described as a new species in 2018 by Ave Suija, Valeriy Darmostuk, and Alexander Khodosovtsev. The type specimen was collected by the third author between the between villages of Burkuty and Prominin in Hola Prystan Raion (Kherson Oblast); there, it was found growing on the foliose lichen Cetraria aculeata , which itself was growing in sand dunes. The species epithet honours Estonian lichenologist and botanist Hans Trass, [1]
Didymocyrtis trassii has pycnidial conidiomata of the Phoma -type. The pycnidia are black and more or less spherical, and partially immersed in the host thallus. They are typically 70–100 μm in diameter, with a wall that is 25–35 μm thick. The conidia are 14.2–18.2 by 5.0–7.2 μm. A sexual stage for the fungus is not known. [1]
Didymocyrtis trassii is only known to occur in southern Ukraine, and it only parasitises Cetraria aculeata growing on sand. The fungus grows on the lower branches of the thick cushions of the lichen, and does not appear to cause damage to the host. [1]
Didymocyrtis is a genus of lichenicolous fungi in the family Phaeosphaeriaceae. The genus was circumscribed by Finnish lichenologist Edvard August Vainio in 1921, with Didymocyrtis consimilis assigned as the type species.
Cetraria aculeata or the spiny Iceland lichen is a dark brown to black fruticose, soil Iceland lichen from the family Parmeliaceae. The species was first described by German naturalist Johann Christian Daniel Edler von Schreber in 1771 under the name of Lichen aculeatus. Later on Erik Acharius, the "father of lichenology" gave it a name of Cornicularia aculeata, which lately has been changed to Coelocaulon aculeatum. Finally the taxonomic revision of Ingvar Kärnefelt and colleagues assigned the species to the genus Cetraria.
Phacopsis australis is a species of lichenicolous (lichen-dwelling) fungus in the family Parmeliaceae. It is found in a few locations in South Africa, where it grows on the thalli of several species of the leafy lichen genus Xanthoparmelia. Unlike other members of genus Phacopsis, the fungus does not induce the formation of galls in its host.
Nanostictis caucasica is a species of lichenicolous (lichen-eating) fungus in the family Stictidaceae. It is known to occur only in a single locality in the North Caucasus region of Southern Russia, where it grows parasitically on the foliose lichen Parmelia sulcata.
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.
Buelliella lecanorae is a species of lichenicolous (lichen-eating) fungus in the class Dothideomycetes. It is found in a few locations in Estonia and in Crimea, where it grows parasitically on members of the Lecanora subfusca species group.
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.
Neoechinodiscus kozhevnikovii is a species of lichenicolous (lichen-eating) fungus in the order Helotiales. It is known to occur in Russia, Austria, and Switzerland, where it grows parasitically on lichens in genus Cetraria.
Endococcus hafellneri is a species of lichenicolous (lichen-eating) fungus in the family Verrucariaceae. It is found in North Asia and the Russian Far East, Estonia, and Japan, where it grows on the lobes of the lichens Flavocetraria cucullata and Cetraria islandica.
Graphium samogiticum is a little-known species of lichenicolous (lichen-eating) fungus in the family Microascaceae. It is found in Lithuania, where it parasitises two lichen species that inhabit abandoned gravel pits.
Phoma candelariellae is a species of lichenicolous (lichen-eating) fungus in the family Didymellaceae. It is found in the Central Anatolia Region of Turkey and in Ukraine, where it grows parasitically on the apothecia of the saxicolous (rock-dwelling) lichen Candelariella aurella.
Sergey Yakovlevich Kondratyuk is a Ukrainian botanist specialising in lichenology. His research deals with the taxonomy, floristics, ecology and geography of lichens and lichenicolous fungi. He has worked at the M.G. Kholodny Institute of Botany of National Academy of Sciences of Ukraine for more than 40 years. In 2014 Kondratyuk was awarded the State Prize of Ukraine in Science and Technology.
Bacidia rubella is a species of lichen in the family Ramalinaceae.
Cetraria laevigata is a species of ground-dwelling, fruticose (bushy) lichen in the family Parmeliaceae. It was formally described as a new species by Russian lichenologist Kseniya Aleksandrovna Rassadina in 1943. In North America, it is commonly known as the striped Iceland lichen.
Abrothallus welwitschii is a species of lichenicolous fungus in the family Abrothallaceae. It grows on species of the foliose lichen genus Sticta. The type specimen was originally collected in Portugal in 1840 by Austrian botanist Friedrich Welwitsch, and it is after him for whom the species is named. Camille Montagne described the species in 1851, but he did not published the name validly; it was published validly by Charles Tulasne a year later.
Abrothallus boomii is a species of lichenicolous fungus in the family Abrothallaceae. Found in Portugal, it was formally described as a new species in 2015 by Ave Suija and Sergio Pérez-Ortega. The type specimen was collected north of Ervas Tenras in a pine-oak forest along a vineyard, where it was found growing on the thallus of a Nephroma lichen. It is only known to occur at the type locality. The species epithet honours Dutch lichenologist Pieter van den Boom, "author of a long list of research articles and indefatigable collector of lichens and lichenicolous fungi".
Abrothallus etayoi is a species of lichenicolous fungus in the family Abrothallaceae. Found in Mexico, it was formally described as a new species in 2015 by Ave Suija and Sergio Pérez-Ortega. The type specimen was collected from Angahuan (Michoacán) at an elevation of 2,470 m (8,100 ft); there, in a pine-oak forest, it was found growing on a Sticta lichen that itself was growing on oak. The species epithet honours Spanish lichenologist Javier Etayo, "a keen collector of lichenicolous fungi and lichens".
Abrothallus granulatae is a species of lichenicolous fungus in the family Abrothallaceae. Found in South America, it was formally described as a new species in 1994 by Swedish lichenologist Mats Wedin. The type specimen was collected by the author on the eastern shore of Lago Roca in Tierra del Fuego National Park, where it was found on the thallus of the foliose lichen Pseudocyphellaria granulata, which itself was growing on the base of a dead Nothofagus tree. The species epithet of the fungus refers to the epithet of its host lichen. The anamorph form of the fungus was concurrently named Vouauxiomyces granulatae. Characteristics of the fungus include the dense clusters formed by its apothecia, and its 2-septate ascospores. Abrothallus granulatae has also been collected in Chile.
Abrothallus secedens is a species of lichenicolous fungus in the family Abrothallaceae. Found in Africa, South America, and the United States, it was formally described as a new species in 1994 by Swedish lichenologists Mats Wedin and Rolf Santesson. The type specimen was collected by the first author on the Martial Glacier in Ushuaia at an altitude of 550 m (1,800 ft), where it was found on the thallus of the foliose lichen Pseudocyphellaria dubia, which itself was growing on the base of a Nothofagus antarctica tree. It has also been collected in Chile, Kenya, and Alaska. The species epithet of the fungus, secedens refers to the two-celled ascospores that eventually separate into single-celled part spores. Known hosts for Abrothallus secedens include Crocodia aurata, Pseudocyphellaria dubia, P. mallota, P. obvoluta, and other Pseudocyphellaria lichens not identified to species.
Abrothallus halei is a species of lichenicolous fungus in the family Abrothallaceae. It was formally described as a new species in 2010 by lichenologists Sergio Pérez-Ortega, Ave Suija, David Leslie Hawksworth, and Rolf Santesson. The type specimen was collected by Cliff Wetmore east of Hare Lake at an elevation of 550 m (1,800 ft); there it was found on the foliose lichen Lobaria quercizans, which itself was growing on the bark of Acer saccharum. The fungus has also been collected in West Virginia, Maine, as well as in Norway. The species epithet honours American lichenologist Mason Hale.
