Stirtonia is a genus of lichen-forming fungi in the family Arthoniaceae. It contains 22 species of corticolous (bark-dwelling) crustose lichens found primarily in tropical regions. The genus was circumscribed by the British lichenologist Annie Lorrain Smith in 1926, with Stirtonia obvallata assigned as the type species. The species epithet honours the Scottish lichenologist James Stirton.
Sphaerellothecium is a genus of fungi in the family Phyllachoraceae. All of the species in the genus are lichenicolous, meaning they grow parasitically on lichens.
Endococcus is a genus of lichenicolous (lichen-dwelling) in the family Lichenotheliaceae. It has 44 species. The genus was circumscribed by the Finnish botanist William Nylander in 1855. Although at least one source places the genus in the Verrucariaceae, a 2016 study of the type species, Endococcus rugulosus, determined that it should instead be placed in the family Lichenotheliaceae of the order Dothideales; this classification echoes a placement proposed in 1979 by David Hawksworth.
Zwackhiomyces is a genus of lichenicolous fungi in the family Xanthopyreniaceae. The genus was circumscribed by Martin Grube and Josef Hafellner in 1990, with Zwackhiomyces coepulonus assigned as the type species.
Menegazzia dissoluta is a species of corticolous (bark-dwelling), foliose lichen found in Papua New Guinea. It was formally described as a new species in 2001 by lichenologists Peter Wilfred James, André Aptroot, Emmanuël Sérusiaux, and Paul Diederich. The type specimen was collected by Harrie Sipman in Mount Gahavisuka Provincial Park (Goroka) at an altitude of 2,300 m (7,500 ft); there it was found growing as an epiphyte on a fallen Castanopsis tree in a mossy, mountainous forest. The species epithet dissoluta refers to the "irregularly finely wrinkled upper surface that dissolves into soredia".
Zwackhiomyces parmotrematis is a species of lichenicolous fungus in the family Xanthopyreniaceae. Found in Suriname, it was formally described as a new species in 2018 by Dutch lichenologist Pieter van den Boom. The type was collected west of Groningen in an abandoned Citrus orchard. Here it was found growing on the thallus of Parmotrema praesorediosum. The fungus does not cause visible damage to its host, such as discolouration or the formation of galls; rather, it produces tiny black, spherical perithecia that are immersed in the host thallus. The specific epithet parmotrematis refers to the genus of its host lichen.
Henricus (Harrie) Johannes Maria Sipman is a retired Dutch lichenologist who specialised in tropical and subtropical lichens and authored or co-authored over 250 scientific publications. He was the curator of the lichen herbarium at the Berlin Botanical Garden and Botanical Museum from 1983 until his retirement in 2010.
Sporopodiopsis sipmanii is a species of foliicolous (leaf-dwelling), crustose lichen in the family Pilocarpaceae. Found in Sabah, Malaysia, it was formally described as a new species in 1997 by Belgian lichenologist Emmanuël Sérusiaux. The type specimen was collected by Harrie Sipman from Mount Kinabalu; the species name sipmanii acknowledges him. The lichen produces asexual spores (conidia) within curved, dorsiventral structures called campylidia; the presence of apothecia in addition to campylidia readily distinguishes it from the other species in the genus, Sporopodiopsis mortimeriana.
Pertusaria sipmanii is a species of crustose lichen in the family Pertusariaceae. Found in Papua New Guinea, it was formally described as a new species in 1998 by Alan Archer and John Elix. The species epithet sipmanii honours Dutch lichenologist Harrie Sipman, who collected the type specimen.
Heiomasia is a genus of corticolous (bark-dwelling), crustose lichens in the family Graphidaceae. It has five species.
Sclerococcum sipmanii is a rare species of lichenicolous fungus in the family Dactylosporaceae. Found in Malaysia, it was formally described as a new species in 2015 by Belgian mycologist Paul Diederich. The type specimen was found on the southern slope of Mount Kinabalu at an altitude of 2,800 m (9,200 ft); here, in a mossy forest on a mountain ridge, it was found growing on the lichen Anomomorpha cf. roseola. The fungus forms black, convex, rounded sporodochia typically measuring 100–200 μm in diameter; the fungus does not otherwise cause visible damage to the host lichen. Sclerococcum sipmanii is only known to occur at the type locality. The species epithet honours Dutch lichenologist Harrie Sipman, one of the collectors of the type.
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.
Stereocaulon glareosum is a species of snow lichen belonging to the family Stereocaulaceae.
Sphaerellothecium araneosum is a species of lichenicolous fungus in the family Phyllachoraceae.
Sphaerellothecium stereocaulorum is a species of lichenicolous fungus in the Phyllachoraceae family.
Phacopsis vulpicidae is a species of lichenicolous (lichen-dwelling) fungus in the family Parmeliaceae. It was formally described as a new species in 2019 by mycologists Mikhail P. Zhurbenko and Paul Diederich. The type specimen was collected by the first author near the headwaters of Ar Khordolyn gol River in Renchinlkhümbe Somon, at an altitude of 2,050 m (6,730 ft). There, in the upper limit of a Larix sibirica forest, the fungus was found growing on the thallus of a ground-dwelling Vulpicida juniperina lichen. The species epithet vulpicidae refers to the genus of its host. Infections by the fungus cause blister-like (bullate) swellings of the host thallus. It is known to occur in arctic and mountain tundra and taiga biomes of Asia, Europe, and North America (Alaska). Its only recorded host is Vulpicida juniperina, and almost all recorded host specimens have been terricolous.
Stigmidium cerinae is a species of lichenicolous (lichen-dwelling) fungus in the family Mycosphaerellaceae. It was formally described as a new species in 1994 by mycologists Claude Roux and Dagmar Triebel. The type specimen was collected in Austria from the apothecia of the muscicolous (moss-dwelling) species Caloplaca stillicidiorum. It infects lichens in the genus Caloplaca, and more generally, members of the family Teloschistaceae. Infection by the fungus results in bleaching of the host hymenium.
Caloplaca sipmanii is a species of corticolous (bark-dwelling), crustose lichen in the family Teloschistaceae. Found in Queensland, Australia, it was formally described as a new species in 2009 by the lichenologists Sergey Kondratyuk, Ingvar Kärnefelt, John Elix, and Jan Vondrák. The type specimen was collected by the third author from Baga National Park at an elevation of 50 to 150 m, where it was found growing on Eucalyptus bark. The species epithet of this lichen pays homage to the Dutch lichenologist Harrie Sipman, in whose honour the volume featuring this species was dedicated. Caloplaca sipmanii contains lichexanthone as a major lichen product.
Micarea sipmanii is a rare species of corticolous (bark-dwelling) lichen in the family Pilocarpaceae. It was described as a new species in 2009 by the lichenologists Emmanuël Sérusiaux and Brian John Coppins. The species epithet honours Dutch lichenologist Harrie Sipman. The type specimen was collected by the first author from the Riviere duy Grand Carbet,, where it was growing in a wet forest. It is known to occur only at the type locality, despite searches for it on other parts of the island. Its primary morphological characteristics is its arbuscular pycnidia, which the authors describe as "spectacular".
Phaeographopsis is a genus of script lichens in the family Graphidaceae. It has three species.
