Seaver: Hypocreales of North America 81 



entirely immersed or with the ostiola shghtly protruding, darker 

 than the stroma; asci cyHndrical, 8-spored; spores i-seriate, 

 strongly overlapping, fusiform, with an apiculus at each end, 

 i-septate, not constricted or constriction so slight as to be scarcely 

 noticeable, strongly verrucose, hyaline or very pale yellowish, 

 35-40 X 8-9 mic. 



On some gill fungus. 



Type locality: Alabama. 



Distribution : Known only from type locality. 



Epecimens examined : Alabama, Earle & Baker. 



From various descriptions this was at first thought to be 

 Hypomyces ochraceus (Pers.) Tul. A note from Leiden how- 

 ever states that there is no material of SpJiacria ochracea Pers. 

 to be found in Persoon's herbarium. This species was originally 

 reported as terrestrial while our specimens are parasitic on gill 

 fungi. In the absence of type material it is impossible to state 

 what Persoon's specimens really were but the descriptions usu- 

 ally represent them as having large, smooth, strongly constricted 

 spores. The spores of the present species conform well in size 

 but differ in being unconstricted and strongly verrucose. This 

 together with its parasitic habits would seem to distinguish our 

 species from Persoon's.
