Pleurocystidia and cheilocystidia not differentiated, (.ill trama <>l 

 subparallel to slightly interwoven hyphae, the cells 57-159 7 

 and usually filled with yellowish contents. Pileus trama homogeneous 

 beneath a turf-like covering of hyphae with their Free ends projecting, 

 their terminal elements 66-122 x 8-22 /<, apices rounded, all parts 

 yellowish in iodine. Clamp connections present but rare at times. 



Habit, Hahuvi. and Dim iuiu i ion — Gregarious to subcaespitose 

 on rich humus, soil, decaying logs, moss-covered logs, in bogs, eastern 

 North America, July-October; also famaica ( Dennis. L953 >, Venezuela 

 (Dennis, 1961), and Trinidad; Dennis suggests that the form reported 

 from Trinidad by Baker and Dale ( L951 ) would apparently be 

 called //. turundusby Smith and Hesler (1942). In the sense of Lange 

 it appears to be what Smith and Hesler called //. miniatUS var.

Observations — This species differs from //. miniatus in its taller, 

 more slender stature, arcuate-decurrent lamellae, paler colors, and 

 drier pileus. Kauffman in an unpublished manuscript had arranged 

 H. cantharellus in section Camarophyllus and H. miniatus in Hygro- 

 cybe. The two species are too closely related to allow for their arrange- 

 ment in different sections. H. cantharellus is separated From //. 

 turundus by its smaller spores and by the lack of fuscous colors in the 

 tips of squamules and fibrils over the disc of the pileus.
