Contribution to European representatives of the genus Hygrocybe: Two new species and neotypification of Hygrocybe mucronella.

Hygrocybe alpina and Hygrocybe amara are described here as new species closely related to Hygrocybe mucronella. Hygrocybe alpina is described from Slovakia and Sweden, but is probably more widespread, especially in alpine regions of Central and Northern Europe. Hygrocybe amara, a well delimited species based on molecular characters, is known only from Slovakia, but probably it is more widespread across Europe and misidentified as H. mucronella s.s. Hygrocybe mucronella is neotypified here, because no type material has been preserved. A fully amended description is given based on molecular evidence and morphology.
