Hymenium
Smooth in the early (white) stage, later becomes covered by golden-yellow or reddish-brown spore masses, final sexual stages produce perithecia giving it a crusted texture
Spore print
Spore print white (early asexual stages), yellow when spore coating is abundant, sexual sporulation less visible for spore print
Ecology
Parasitic on bolete mushrooms (Boletaceae), begins infecting the pore surface and spreads over cap and stem, summer through autumn, more noticeable in wet seasons
Edibility
Toxic
Chemical reactions
Aleuriospores golden-yellow in KOH

Spores:
Description
Asexual: Ellipsoid, smooth, hyaline; ~ 8-12 × 3.5-5 µm.
Description
Aleuriospores: Round, warty/spiny, yellow; ~ 9-20 µm diameter.
Description
Ascospores (sexual): Fusiform to lanceolate, often bi-septate or bicellular, ~ 20-30 × 4-6 µm.
