Collections examined from Denmark On Enochrus coarctatus (Gredler, 1863) (Col. Hydrophilidae ) DENMARK – Nordøstsjaelland (NEZ) • Heatherhill ; 56°5.240′ N , 12°8.611′ E ; UC21; 22 May 2016 ; JP 94 ; JP det.; ZMUC C-F-122569 . Remarks First record from Denmark . 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 Phurmomyces has been questioned as a probably similar growth form of Ceratomyces ( Tavares 1985 ) .
