Multiclavula mucida

Multiclavula mucida is a globally distributed species of basidiolichen belonging to the family Hydnaceae. Since its initial classification by Christiaan Hendrik Persoon in 1797, the species has been described under various synonyms and associated with multiple genera. Persoon described its fruiting bodies as gregarious (i.e. growing in groups but separate at the base), varying from simple to branching structures, predominantly whitish in colour with yellow to brownish tips. He also noted its frequent appearance in autumn on decaying, moist wood, often covered with a greenish crust necessary for its growth. The cosmopolitan distribution of Multiclavula mucida and its variability in appearance have led to a complex nomenclature and historical confusion with other species and genera. Though widespread, it is considered rare in Europe and faces threats in many countries. It can be distinguished from similar species such as Multiclavula petricola, M. vernalis, M. coronilla, and Clavicorona ......read more on Wikipedia.
