Fiji;. 62. //. purus 



reagent, white in deposit. Basidia 37-58 X 6-7(8) /*, 4-spored, rarely 

 2-spored. Pleurocystidia and eheilocystidia not differentiated. Gill 

 trama subparallel to very slightly interwoven, hyphae 8-13 p broad, 

 yellowish in Melzer's reagent. Cuticle of colorless, gelatinous hyphae. 

 3-6(10) fx broad. No hypodermium differentiated. The pileus trama is 

 of broad, 6-10(20) /x, hyphae which are loosely and radially disposed. 

 Even though radial, the hyphae tend to be interwoven. Clamp connec- 

 tions present on the cuticular hyphae. 



Habit, Habitat, and Distbibution — In deep humus, mixed 

 woods, New York, North Carolina, and Alabama, August-October. 



Matebial Studied — Alabama: Burke 86. new yobk: Peck (type, 

 from Crogham, Lewis County), nobth cabolina: Hesler 12290. 



Obsebvations — Notes on the type: Spores 7-9 X 4.5-5.5 p, ellip- 

 soid, smooth, pale yellow in Melzer's reagent. Basidia 41-53 X 7-8 /x, 

 2- and 4-spored. Gill trama subparallel to very slightly interwoven, 

 hyphae 4-8(12) /x broad. Cuticle of gelatinous hyphae. Clamp connec- 

 tions rare on the cuticular hyphae. Hesler's No. 12290, from North 

 Carolina, agrees with the type. 



In section the stipe shows a thick outer coating of slender, gelat- 

 inous hyphae similar to that found in //. psitt acinus. Similar hyphae 

 project from the surface of the pileus and become matted together
