Hypomyces chrysospermus

Sporocarp
Fruiting body, a white, soon yellow, cottony layer overgrowing the surface of a host mushroom, usually a member of the Boletaceae. Three kinds of spores are produced during the life cycle, two asexual and one sexual. The sexual phase, seldom seen because the host has usually rotted beyond recognition, consists of perithecia, asci, and ascospores. The ascospores according to Rogers and Samuels are fusiform to lanceolate, unequally bicellular, 20-25 x 4-5 µm. Two types of asexual spores are produced:
1. elliptical, thin walled, smooth, hyaline, 8-12 x 3.5-5.0 µm.
2. round, spiny, yellow, 9-20 µm.

Hypomyces lactifluorum

Sporocarp
Fruit-body a bright-orange mold growing on the surface of members of the Russulaceae (in California usually Russula brevipes); gills of the parasitized host reduced to folds; in age, minute, reddish-orange perithecial mounds develop (use hand lens); context of host firm, brittle, if Lactarius, then oozing a latex; odor at first fungal, then of shellfish; taste mild in R. brevipes, potentially peppery if Lactarius.
