Family 22. ENGLERULACEAE 



22:26, 24:229; TS 467 



Mycelium superficial, bright-colored or dark, septate, straight-walled, with or 

 without hyphopodia, sometimes lacking; perithecia superficial, globoid, astomous, 

 sessile or stalked, parenchymic or with meridian hyphae, wholly or partly breaking 

 up by a slimy histolysis; asci single or in basal clusters, mostly without paraphyses. 



In a critical account of this family, Petrak (Ann. Myc. 26:385-413, 1928) has 

 eliminated nearly two-thirds of the genera referred to it by Theissen and Sydow 

 in their monograph. Five become synonyms and five are treated as doubtful.
