Mycologia 



Type locality : Catskill Mts., New York. 

 Distribution : New York to Virginia. 



Specimens examined: New York, Peck (cotype), Seaver 

 (various collections) ; Virginia, Murrill, 4^6, ^j/, 4^8, ^jp. 



The present species was not originally described as a Hypo- 

 myces since the plants do not occur on other fungi as is usually 

 the case. Dr. Peck (1. c.) states: "The spores of Hypocrea 

 apiculata resemble those of this {Hypomyces transformans) and 

 other species of Hypomyces but the plant is not parasitic on 

 fungi an essential character in the genus Hypomyces as at pres- 

 ent defined." After examination of specimens collected by the 

 writer and determined by Dr. Peck it was concluded that this 

 species was a typical Hypomyces and a note from the same man 

 later sustained me in this conclusion. 



The genus Clintoniella (Sacc.) Rehm was based on this species 

 and was distinguished from Hypocrea by the fusiform spores. 

 The latter genus is therefore not well founded. 



A specimen of Hypomyces xylophilus Peck, collected in Ohio 

 by Morgan and which is apparently cotype has been studied. 

 This appears to be a faded and rather poor specimen of the above 

 species, which often occurs on wood and rubbish of various 

 kinds.

Subiculum effused, at first whitish, becoming orange or rust- 

 colored, often covering an area of 5-8 cm. or in smaller, inter- 

 rupted patches ; perithecia thickly gregarious or crowded, orange, 

 darker than the subiculum ; subconical, with the ostiola strongly 

 protruding, occasionally with the subiculum almost wanting in 

 weathered specimens; asci cyHndrical, 8-spored, with the spores 

 slightly overlapping; spores fusiform, usually a little curved, with 

 a medial septum and a short apiculus at each end, becoming 

 strongly verrucose at maturity (pi. 21, /. p). 



On decaying fungi of various kinds. 



Type locality: Europe.
