Notes:
basidia four-spored with horn-like sterigmata; cystidia probably absent (but many basidiole impersonators); hyphal system apparently monomitic but of two types, subhymenial hyphae thin walled, hyaline and without clamps, basal hyphae significantly thicker (but not thick walled) with large and abundant clamps; spores brown, ellipsoid and apiculate, inequilateral in side view, some collapsed, walls cyanophilic (i think).

Spores:

(8) 8.5 – 10.3 (10.8) × (4.3) 4.5 – 5.4 (5.7) µm
Q = (1.5) 1.7 – 2 (2.5) ; N = 50
Me = 9.4 × 5 µm ; Qe = 1.9
