Scopuloides rimosa

On rotten decaying wood on the ground, especially beech, with resupinate basidiomes tightly adhering to the substrate, greyish white with bluish tints; hymenium formed by fine short aculei up to 0.3 mm high; waxy in consistency.

Hyphal system monomitic, formed by hyaline, thin- to thick-walled hyphae, densely interwoven, 4 to 8 µm in diameter, profusely branched, septate with simple septa (without clamp connections).

Cystidia very abundant, very thick-walled, of lamprocystidium type, 35 to 50 µm long and 6 to 12 µm wide, intermixed with some emergent cylindrical septocystidia up to 90 µm high.

Basidia cylindrical-clavate, 20 to 30 µm long, 3 to 4.5 µm wide, simple-based and four-spored.

Spores ellipsoidal to very slightly allantoid, smooth, hyaline, thin-walled, with an eccentric apiculus at one end, 3.5 to 4.5 µm long, 1.5 to 2.5 µm wide, containing oil droplets of varying size inside, and inamyloid in Melzer's reagent.
