Spores (23-) 25-30 (-32) × 11-13 μm, elliptical to slightly subfusoid, often slightly inequilateral, hyaline, smooth, with 1-3 (-4) guttules; paraphyses closely septate especially toward the tips; hymenial hairs straight, not-septate; flesh divided into a brownish subhymenium of thick textura intricata, a medullary excipulum of loose, hyaline, highly gelified textura intricata, a brown ectal excipulum of textura globulosa to subglobulosa; external hairs mainly hyphoid, heavily encrusted by a brownish crystalloid pigment, but also olivaceous true hairs are present, although in a less percentage. Differs from Sarcosoma globosum in black colors and the absence of moniliod external hairs; from Plectania species in bigger size, more gelatinous flesh, and a different morphology of the external hairs.
