Material Studied — Massachusetts: Bigelow 8361, 8362, v 

 (type, from Savoy Mt. State Forest. Florida, Mass.. Aug. 17. L9E 

 8364, 8365. 8421, 8422, 9086. 



Observations — As Bigelow and Barr state (I960), the purplish 

 gills are unusual for species in Hygrocybe. Here we may recall gill- 

 color in H. trot/anus and H. mephiticus. In //. troyanus the gills are 

 violaceous, according to Mnrrill (salmon orange according to Dennis . 

 but the hemispheric to convex, ferruginous pileus. and shorter spores 

 will separate it from H. purpureofolius. In H. mephiticus the gills are 

 grayish-violaceous to grayish purple, but the gills are sinuate, the 

 pileus is yellowish brown, and the fruiting bodies have a mephitic 

 odor. 



Notes on the type: Cuticle of repent hyphae, 3-5 p broad, non- 

 gelatinous, hyphae undifferentiated from those of the pileus trama. 

 No hvpodermium. Pileus trama of radial and subparallel hyphae; 

 septa relatively numerous and close together.
