Black Witch's Butter Exidia glandulosa (Bulliard) Fries    Synonyms: Black Witches' Butter.
Kingdom Fungi   >   Phylum Basidiomycota   >   Class Tremellomycetes   >   Order Tremellales   >   Family Exidiaceae   >   Genus Exidia   

Description:

Fruiting body: Blackish; irregular shapes fused into a mass; shiny; flesh gelatinous; usually covered with peg-like warts (use a hand lens). Microscopically indistinguishable from E. nigricans; however, Woehrel and Light (2017, p. 107) state: fruiting bodies of E. glandulosa "nearly always retain their discrete identity," while E. nigricans coalesces into a black, wrinkled mass (J. Solem, pers. comm.).

Relationships:

Found on hardwoods.
