Thelephra bryophila (Pers.) Kõljalg, I. Saar & Svantesson 2024 s.str.

Syn.: Tomentella bryophila (Pers.) M.J. Larsen 1974

Basidiome: adherent, loosely felty to mold-like
Hymenophore: smooth, rust to mustard-colored
Margin: same color as or darker than the hymenophore, inconspicuous
Rhizomorphs: absent
Subiculum: darker than the hymenophore, brown

Subicular hyphae: brownish, with clamps, thick-walled, partially encrusted, 4-7 µm wide
Subhymenial hyphae: yellowish, with clamps, thin-walled, not encrusted, 4-6 µm wide
Cystidia: absent
Basidia: hyaline to yellowish, with basal clamp
Spores: yellow-brownish, rounded in both frontal and lateral view, 8-11 µm, apiculus amyloid, spines up to 3 µm long

Distribution: considered a common species in Germany
Note: The typical form of the species is well recognized by its long-spined, round spores and rust-colored hymenophore. The complex includes records with an olive-colored hymenophore =Thelephora viridescens and records with similarly rust-colored hymenophore and short-spined, smaller spores =Thelephora ferruginella. However, these two species lack an amyloid apiculus.
