MATERIAL EXAMINED 
VENEZUELA: on dead wood, Mapire, May, 1887, A. Gatllard 6 
(NY). 
This species seems to differ from the preceding only in the 
larger spores. In the herbarium of the New York Botanical 
Garden is a specimen of what appears to be the original and only 
collection. The above description is that of the authors supple- 
mented by notes drawn from the above mentioned specimen. 
In the original description the tissue is spoken of as elastic, some- 
what like that of Bulgaria. The dried material is friable. It 
breaks up so that no complete ascus has been seen. The material 
becomes deep violet on treatment with KOH.
