300 SECTION HYGROPHORUS 



of gelatinous tangled hyphae 3-5 p broad, and hyaline in KOH. Clamp 

 connections present. 



Habit, Habitat, and Distribution — Gregarious to scattered under 

 oak, Stinchfield Forest, Dexter, Mich., Oct. 30, 1961. 



Material Studied — Michigan: Smith 64785. 



Observations — The lamellae remain white to pallid in drying, a 

 character at once distinguishing the species from H. occidentalis. In 

 the latter the gills are at first white then tinged cream, and the pileus 

 and stipe are more glutinous than in H. mesotephrus. 



The original description characterizes the pileus as white with a 

 brown disc, viscid and striate. At maturity the pilei in Smith's No. 

 64785 were whitish on the margin and avellaneous on the disc. The 

 striations mentioned in the original description were not described in 

 more detail, and thus we do not know whether they were slight 

 sulcations (which is probable) or translucent striations. The illustration 

 covers our material rather well, and the English authors mentioned the 

 stains lower down on the stipe. If mature specimens are compared, our 

 material is too close to H. mesotephrus as originally described to be 

 placed anywhere else.
