Merulicium
Merulicium J. Erikss. & Ryvarden 1976, in Gorjón, Studies in Fungi 5(1), 239 (2020).
Diagnosis: Basidiome resupinate, thin, pellicular, hymenophore merulioid when fresh, more or less smooth when dry, margin fibrillose with thin rhizomorphs. Hyphal system dimitic, generative hyphae with clamps, thin-walled, skeletal hyphae thick-walled, dextrinoid. Cystidia (leptocystidia), obclavate, with an obtuse or slightly widened apex, thin-walled. Basidia clavate, with 4-sterigmata and a basal clamp. Basidiospores fusiform, smooth, thin-walled, IKI–, CB–.
Merulicium differs from other athelioid species in the dimitic hyphal system with dextrinoid skeletal hyphae (Eriksson & Ryvarden 1976). Phylogenetically, it belongs to the Pterulaceae in the Agaricales (Larsson 2007).
