According to Majewski (1994b), thalli of this species are differentiated into two forms which are seemingly related with the host surface points undergoing contact through mating behaviour ( Scheloske 1969); the form B between the claws of tarsi of both anterior legs in male insects, and the form A or normal form under the right anterior margin of female pronotum. We have only found the claw form that is regarded to be more frequent ( Majewski 2008). Such reduced forms (see also  Autoicomyces humilis) pose true taxonomical problems. Moreover, the monotypic genus  Phurmomyceshas been questioned as a probably similar growth form of  Ceratomyces( Tavares 1985). 4988641106 Germany Germany 29 30 1 holotype 4988642080 2016-05-22 JP Denmark JP 56.087334 Heatherhill 1 12.143517 29 30 ZMUC C-F-122569 1 Nordostsjaelland
