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.
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.
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 Dutch lichenologist. He specialises in tropical and subtropical lichens, and has authored or co-authored more than 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.
Astrothelium sipmanii is a species of corticolous (bark-dwelling) lichen in the family Trypetheliaceae. It is found in Guyana.
Lobariella sipmanii is a species of foliose lichen in the family Peltigeraceae. It is found in high-altitude páramo in Cundinamarca, Colombia.
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.
Astrochapsa sipmanii is a little-known species of corticolous (bark-dwelling) lichen in the family Graphidaceae. It is found in Singapore.
Pertusaria sipmanii is a species of crustose lichen in the family Parmeliaceae. 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.
Bulbothrix sipmanii is a species of lichen in the family Parmeliaceae. Found in Guyana, it was formally described as a new species in 1999 by André Aptroot and Robert van Aubel. The species epithet sipmanii honours Dutch lichenologist Harrie Sipman.
Heiomasia is a genus of corticolous (bark-dwelling), crustose lichens in the family Graphidaceae. It has five species.
Coenogonium beaverae is a species of corticolous (bark-dwelling), crustose lichen in the family Coenogoniaceae. Found in Seychelles, it was formally described as a new species in 2017 by Robert Lücking and Paul Diederich. The type specimen was collected by the second author in a disturbed rainforest near the Sauzier Waterfall at altitudes between 20 and 70 m. It is only known from the type locality. The species epithet beaverae honours Katy Beaver, "who generously gave support and assistance during the field trip of the first author to several Seychelles islands, and who is extremely active in the protection of the environment in Seychelles".
Imshaugia sipmanii is a species of saxicolous (rock-dwelling) lichen in the family Parmeliaceae. Found in Venezuela, it was formally described as a new species in 2004 by Australian lichenologist Jack Elix. The species epithet honours Dutch lichenologist Harrie Sipman, who collected the type specimen.
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.
