Observations — Notes on the type: Spores 7-9 X 4.5-6 ^, ellipsoid 

 to subovoid, smooth, yellowish in Melzer's reagent. Basidia 37-44 X 

 7-8 fi, 4-spored. Pleurocystidia and cheilocystidia none. Gill trama 

 subparallel to slightly interwoven. Cuticle fibrillose, non-gelatinous. 

 Clamp connections none. 



This is a very distinctive fungus readily characterized by the 

 manner in which the gills hold their orange-yellow color after the other 

 parts have faded or after the fruiting bodies have been dried. Our 

 observations verify Kauffman's statement that the species is not viscid. 

 The apparent viscidity occasionally noted is not caused by a gelatinous 

 pellicle, but is rather the slight tackiness one frequently gets from 

 contact with a moist surface. In many respects the species is related to 

 H. calyptraeformis, but differs in color, stature, and in the absence of 

 cystidia on the gills.
