Kullhemia P. Karst., Meddn Soc. Fauna Flora fenn. 2: 182 (1878)

Lichenized on wood. Sexual morph: Thallus crustose, granular, sometimes scurfy, often sparse to absent, scattered, solitary, superficial, grey to blackish. Apothecia biatorine, convex, pulvinate, superficial, gregarious or confluent, black, rarely dull blue-black or black brown, translucent when wet. Apothecial wall composed of hyaline to pale brown cells of textura angularis. Hymenium layer composed of asci and paraphyses, with a crust-like excipulum above. Paraphyses densely anastomosed. Asci clavate, multispored, thick-walled with a distinct ocular chamber. Ascospores globose, simple, thin-walled, hyaline. Asexual morph: Undetermined.


Type species – Kullhemia moriformis (Ach.) P. Karst.


Notes The genus Kullhemia was introduced by Karst in 1878 with the type species K. moriformis. There are two epithets under the genus Kullhemia in Index Fungorum (2019). Cultures and sequences are unavailable. The genus Kullhemia and Strangospora share similarities such as a lichenized habit, bitunicate, wedge-shaped asci and aseptate hyaline ascospores. The genus Strangospora is in the subphylum Pezizomycotina, Strangosporaceae, families incertae sedis (Lucking et al. 2016, Doilom et al. 2018). We therefore synonymize the genus Kullhemia under Strangospora and exclude it from Dothideomycetes, genera incertae sedis.
