PERISPORIALES 



Phaeophragmiae 

 Spores x-celled, dark in mass 

 Mycelium without hyphopodia; paraphyses present Hyalotexis 



Family 23. CAPNODIACEAE 

 1:73, 9:438, 11:270, 14:476, 17:555, 22:59, 24:366; TS 471 



Mycelium superficial, rarely subcuticular, dematioid, sometimes straight-walled 

 but the hyphae then agglutinate in skeins, often with setae but hyphopodia only 

 rarely present; perithecia superficial, rarely with innate foot, composed of dematioid 

 cells or of agglutinate, meridian hyphae, never of straight-walled polygonal cells as 

 in Perisporiaceae, soft-fleshy or slimy-cartilaginous to tough-leathery, never car- 

 bonous, globose to elongate-conical, sessile or stalked, hairy or glabrous; ostiole 

 lacking or indefinite, rarely distinct; asci basal-umbellate or parallel, usually 8-sporcd 

 and always without true paraphyses; pycnidia often subulate flask-shaped. 



This family approaches Perisporiaceae so closely on the one hand and 

 Sphaeriaceae on the other that genera on the border-line must be traced in both keys 

 concerned.
