, Gleba firm or powdery, rarely gelatinous, with- 

 out volva or receptacle but enclosed in a 

 peridium 



a. Peridium epigean 



(1) Gleba typically powdery or cellular, en- 



closed in a peridium opening by a defi- 

 nite mouth or irregularly 



(2) Gleba enclosed in seed-like peridioles 



borne in a globoid to funnelform 

 peridium 



b. Peridium hypogean, regularly closed

DEUTEROMYCETES (Fungi Imperfecti) 



A. Conidia present 



1. Conidia in globoid, cupuloid or hysterioid 



pycnidia 



a. Pycnidia perithecium-like, typically globoid, 



ostiolate or astomous 



(1) Pycnidia brown to black, membranous to 



carbonous 



(2) Pycnidia bright-colored or hyaline, fleshy, 



sometimes gelatinous or waxy 



b. Pycnidia dimidiate and usually more or less 



distinctly radiate, rarely hysterioid 



c. Pycnidia apothecium-like or hysterioid, cupu- 



late to discoid, opening circularly or less 

 often by a cleft or lobes, dark and subcar- 

 bonous to bright-colored and fleshy 



2. Conidia not in pycnidia 



a. Hyphae short or obsolete, borne on a more 



or less parenchymoid stroma 



b. Hyphae not on a stroma, typically well-de- 



veloped, but sometimes short or even lack- 

 ing 



(1) Hyphae in more or less loose cottony 



masses 



(a) Hyphae and conidia hyaline or bright- 



colored 



(b) Hyphae and conidia both typically dark, 



or one or the other dark 



(2) Hyphae compacted to form a globose to 



cylindric spore-body which is often 

 stalked 



(a) Spore-body typically sessile, globose to 



pulvinate or applanate, i. e., a sporo- 

 dochium 



(b) Spore-body stalked, capitate to cyl- 



indric, i. e., a synnema 



B. Conidia lacking 



C. Conidia present but criteria indefinite; parasites 



on human skin
