About

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, 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.
