Fruit consisting of sporidia, mostly definite, contained in asci, 
springing from a naked or enclosed stratum of fructifying cells, 
and forming an hymenium or nucleus. — Berk, Outl. p. 357. 
Hymenium wholly enclosed within a fleshy peridium. 
Subterranean . Tuberoideee. 
Hymenium discoid, soon exposed, substance fleshy . . Discomycetea. 
Hymenium at length more or less exposed by fissure of 
coriaceous or carbonaceous receptacle . . Hysteriacea. 
Hymenium enclosed in a minute subglobose perithecium, 
dehiscing by a pore, or rarely irregularly . PyrenomycetetB.

Subglobose, fleshy, becoming indurated, covered with two tegu-

or obovate, shortly pedicellate. Sporidia at first hyaline, when 
mature resolved into a dry, opaque powder, even, spiny, or reticu- 
late.
