Homophron

Homophron (Britzelm.) Örstadius & E. Larss., in Örstadius et al., Mycological Progress 14 (5/25): 35 (2015)

Diagnosis: Basidiomata small to large, fragile to rather rigid, non-deliquescent, lignicolous. Pileus brown, striate, hygrophanous. Lamellae close to crowded. Stem central. Veil absent. Spores small to medium sized, moderately pigmented to hyaline, with indistinct to absent germ pore. Basidia 4-spored. Pleurocystidia often thick-walled and with crystals or incrustations at apex. Pileipellis a hymeniderm or transition to a paraderm. Clamps present.

Index Fungorum number: IF811630

Type species: Homophron spadiceum (P. Kumm.) Örstadius & E. Larss., in Örstadius et al., Mycological Progress 14 (5/25): 35 (2015)

Notes: The combination of absence of veil and presence of thick-walled cystidia with crystals is unique in Psathyrellaceae.
