Calvitimela Cuprea
''Calvitimela'' is a fungal genus in the family Tephromelataceae, comprising 11 species of lichen. These lichens grow tightly attached to rocks, appearing as thin, crustose lichen, crust-like layers on their surface. They are primarily found in alpine and arctic regions around the world. ''Calvitimela'' species are characterised by their (segmented) thallus and black, shiny, convex apothecia (fruiting bodies). The genus currently includes eleven recognised species, though recent genetic studies have revealed unexpected diversity within this group. ''Calvitimela'' lichens are known for their varied secondary metabolites, which can sometimes aid in species identification. However, the taxonomy of the genus remains complex and challenging, with ongoing research uncovering new information about their relationships, distribution, and evolution. These lichens play important ecological roles in their harsh mountain and polar habitats, where they are often among the few organisms able to ...

Hafellner
Josef Hafellner (1951– ) 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 ascus, 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 ...
