Crinipellis tucumanensis

Pileipellis formed by cylindrical to subventricose hyphae, 3–11 µm in diameter, hyaline, thin-walled, finely encrusted, colourless, giving rise to setiform terminal elements up to 450 µm long, straight or sinuous, often flexuous in the middle, thick-walled (0.5–1 µm), multiseptate with a rounded apex.

Stipitipellis formed by cylindrical hyphae 2 to 4 µm thick, thin- to slightly thick-walled, pale yellowish-green, turning dark olive green in KOH.

Cheilocystidia very abundant, clavate to subutriform, occasionally subcylindrical, with broad, short, irregular apical outgrowths, often bifurcate, hyaline and thin-walled.

Pleurocystidia scattered, cylindric-clavate, hyaline.

Basidia clavate, with basal clamp connections, 4-spored.

Spores subcylindrical to ellipsoidal, slightly lacrymoid, smooth, hyaline, thin-walled, with an eccentric apiculus, inamyloid in Melzer's reagent.
