SUBSECTION IIYGROPJIORUS 275 



Lamellae decurrent, white at very first, soon pale yellow and finally 

 more or less concolorous with the margin of the pileus, narrow to mod- 

 erately broad, snbdistant to distant. 



Stipe (2.5)8-16 cm X (3)6-12(15) mm, tapering slightly down- 

 ward, flesh whitish or yellowish near the exterior, the lower two-thirds 

 glutinous, partial veil rloccose and leaving a subapical, fibrillose, eva- 

 nescent annular zone, apical region silky and yellowish, variously col- 

 ored below, olive brown, olivaceous yellow, bright yellow, orange or 

 scarlet, solid. 



Spores (from deposit) 7-9 X 4-5 /x, ellipsoid, smooth, white in 

 mass, bright yellow in Melzer's reagent. Basidia 42-60 X 6-7 /x, 4- 

 spored. Pleurocystidia and cheilocystidia none. Gill trama divergent, 

 hyphae 3-7(10) /* broad. Cuticle of gelatinous hyphae. Clamp connec- 

 tions present in the cuticle and gill trama. The minute anatomy of the 

 stipe is as follows: In longitudinal section the component hyphae are 

 subparallel to somewhat interwoven; in transverse section the hyphae 

 are observed as more or less pseudoparenchymatous. In this species the 

 hyphae are not as distinctly parallel as in H. roseibrunneus and there- 

 fore lack the distinct pseudoparenchymatous appearance as observed 

 in the latter species. The cuticle is of gelatinous hyphae which form a 

 distinct zone 150-350 fx thick, hyphae narrow (2.5-4 ti), colorless. Hy- 

 podermium none differentiated or only slightly developed. Pileus 

 trama interwoven, hyphae radially arranged.
