Coniophora puteana

Monomitic hyphal system, formed by hyaline, slender generative hyphae with simple septa, without clamp connections.

Without cystidia, although small, hyaline, sinuous hair-like elements are present among the basidia.

Basidia cylindrical, very elongated (up to 80 µm long), sinuous, with faint oily content, 4-spored.

Spores smooth, large, thick-walled, ochraceous brown under the microscope, with a minute, almost imperceptible apiculus at one end, practically non-reactive in Melzer's reagent (non-dextrinoid).
