248 SECTION HYGROPHORUS 



36-52 X 7-12 fi clavate, apices rounded. Gill trama slightly interwoven 

 to subparallel. Clamp connections on the cuticular hyphae. Epicutis a 

 palisade or fascicles of pilocystidia, 58-88 X 9-18 /x, versiform (clavate, 

 cylindric ) . 



Habit, Habitat, and Distbibution — On soil, under hardwood, 

 Florida, August. 



Material Studied — flobida: Murrill F18045 (type, from near 

 Gainesville, Aug. 13, 1938). 



Obsebvations — We have not seen fresh material. The above de- 

 scription of macroscopic characters is taken from Murrill (1943); that 

 of the microscopic characters is based on our study of the type. 



The nearly globose, amyloid spores, the pleurocystidia, cheilo- 

 cystidia, and pilocystidia are distinctive characters of H. translucens. 

 Under Singer's arrangement (1951), this is called Hydropus translu- 

 cens (Murr.) Singer. The amyloid spores place it Amylohijgwcijbe. 

 A re-study of this species from fresh material may dictate a change in 

 its taxonomic position. It might be a Mycena, but since we have not 

 seen it fresh we have no basis for transferring it. The moderately long 

 basidia indicate Hygrophorus.
