SUBSECTIOX HYGROPHORUS 279 



There seems little to be gained by our commenting on the various 

 related species which have passed under the name II. aureus in Eu- 

 rope. Suffice it to say that Kiihner and Romagnesi recognized //. spe- 

 ciosus in their flora, and their account is convincing enough for us. We 

 cannot agree with Singer (1951) in considering //. aureus as a variety 

 of H. hypothejus, because of the habitat difference; the latter forms 

 mycorrhiza with pine, the former grows under hardwoods. 



Observations in Peck's type: Spores 8-9 X 4.5-5.5 \x, ellipsoid, 

 smooth, pale yellow in Melzer's reagent. Basidia 41-54 x 6-8 \x, 

 4-spored. Pleurocvstidia and cheiloevstidia none. Gill trama divergent, 

 hvphae 4-8 /x broad. Cuticle of gelatinous hyphae. Clamp connections 

 present.

Pileus 2-8 cm broad, campanulate at first, then expanded-umbonate 

 or umbo obsolete in age, bright scarlet red or rosy reddish orange when 

 young, fading near the margin to yellow but remaining orange-red on 

 the umbo, glutinous, pellicle separable, glabrous, margin at first in- 

 curved, soon spreading. Context white, yellow or orange tinted under 

 the pellicle, moderately thick, soft; odor and taste not distinctive. 



Lamellae decurrent, white to pale citrine, distant, rather broad, 

 acute at the ends, intervenose. 



Stipe 3-10 cm long, 8-15(20) mm thick, whitish, equal or subcom- 

 pressed, coated over the lower half with gelatinous universal veil rem- 

 nants, peronate from a thin white-fibrillose partial veil up to the 

 evanescent annular zone, becoming white floccose-fibrillose, variegated 

 with glistening spots from the drying of the gluten, upper portion sub- 

 glabrous, spongy within, rarely hollow.
