Stephanocyclos is a genus of lichen-forming fungi in the family Lecideaceae. [1] It is a monotypic genus, containing the single species Stephanocyclos henssenianus. This crustose lichen was formally described as a new species in 1983 by German lichenologist Hannes Hertel as part of a set of exsiccata (dried herbarium specimens). The type specimen was collected from volcanic rock found on Marion Island, one of the two Prince Edward Islands in the southern Indian Ocean. [2] The specific epithet henssenianus honours lichenologist Aino Henssen. [3]

Its range has since been expanded to include the Falkland Islands and northern Patagonia. X. cataractarum, found in Campbell Island, New Zealand was added to the genus in 2017.

Josef Hafellner is an Austrian mycologist and lichenologist. He was awarded the Acharius Medal in 2016 for his lifetime contributions to lichenology. Before his retirement, he was a professor at the Karl-Franzens-Universität in Graz. Hafellner started developing an interest in lichens while he was a student at this institution, studying under Josef Poelt. He earned a master's degree in 1975 and a PhD in 1978, defending a doctoral thesis about the genus Karschia. In 2003, Hafellner received his habilitation. By this time, he had studied with French lichenologist André Bellemère (1927–2014) at Saint-Cloud, where he learned techniques of transmission electron microscopy and how their application in studying asci could be used in lichen systematics. His 1984 work Studien in Richtung einer natürlicheren Gliederung der Sammelfamilien Lecanoraceae und Lecideaceae has been described as "probably the single most influential publication in lichen systematics in the latter half of the 20th century".

<i>Roccellinastrum</i> Genus of fungi

Roccellinastrum is a genus of lichen-forming fungi in the family Pilocarpaceae. It has seven species.

<i>Schaereria</i> Genus of lichen

Schaereria is a genus of lichen-forming fungi. It is the sole genus in the family Schaereriaceae, which itself is the only family in the Schaereriales, an order in the subclass Ostropomycetidae of the class Lecanoromycetes. Most Schaereria species are crustose lichens that live on rocks. Schaereria was first proposed by Gustav Wilhelm Körber in 1855 and was later taken up by other lichenologists despite periods of disuse.

Lambiella is a genus of lichen-forming fungi in the family Xylographaceae. The genus was circumscribed by German botanist Hannes Hertel in 1984, with Lambiella psephota assigned as the type species.

Pachyascus is the sole genus in the family Pachyascaceae. It contains a single species, the lichen Pachyascus lapponicus. Both the genus and species were described as new to science in 1968 by lichenologists Josef Poelt and Hannes Hertel. P. lapponicus was originally collected from Lapland, a province in northern Sweden. The lichen has several unusual characteristics: it grows exclusively along with the rock moss Andreaea, it bears goniocyst-like parts and produces tiny apothecia that stand in the leaf axils of the moss, and it has thick asci.
