may be more robust than MurrilTs specimens indicate. It is closel) re 

 lated to //. canthareUus, both by the nature of the hyphae covering the 

 pileus and by its slightly interwoven gill trama. The colors clearly dis- 

 tinguish them, however. //. squamulifer Bond, appears to be closely 



related. 



Notes on the type: Spores 7-9(10) X 4-6(7) ft, ellipsoid, smooth, 

 non-amyloid. Basidia 37-60 x 7-9 /x, 4-spored. Pleurocystidia and chei- 

 locystidia none. Gill trama subparallel. Epieutis composed of erect or 

 more or less appressed, tangled hyphae, the free ends of which arc 

 usually swollen. Clamp connections rare in gill trama; none found in
