58 SPHAERIALES 



Family 24. TRICHOTHYRIACEAE 



24:506; TS 15:484 



Mycelium superficial, usually well-developed, rarely evanescent, dark, cottony or 

 forming a membrane, mostly fungicole; perithecia round, radiate, somewhat flattened, 

 the upper and lower walls somewhat unlike, inverted, the morphological base forming 

 the apex with papilla and pore; asci several to many, small, clavate, hanging from 

 the apex; paraphyses typically lacking; spores various.

Aerial mycelium none; stroma innate, then erumpent, flat to pulvinate, black, 

 coriaceous to carbonous; perithecia on the stroma, usually cespitose, elongate, 

 turbinate to flask-shaped, sessile or stipitate, when mature opening widely by means 

 of a cleft or fimbriate-lacerate lobes; asci ovoid, with long slender stalks, 1-8-spored; 

 paraphyses lacking; spores brown to nearly black when mature.

Order 8. SPHAERIALES 



Mycelium typically immersed and scanty, sometimes formirg a subiculum and 

 frequently compacted into a stroma of various types; perithecia innate to superficial, 

 typically globoid, occasionally depressed, cupulate, conical or cylindric, regularly 

 ostiolate, rarely astomous, sometimes with a beak or crest, wall fleshy, membranous, 

 coriaceous or carbonous, bright-colored to dark, frequently hairy or setose, separate.
