Pileus convex, very viscid or glutinous, glabrous, soft, 
shining, golden-yellow, reddish-yellow or chestnut color, the 
margin thin, flesh pale-yellow, becoming less bright or dingy 
on exposure to the air; tubes nearly plane, adnate or sub- 
decurrent, swal/, angular or subrotund, pale-yellow, becom- 
ing dingy-ochraceous with age, changing to brown or pur- 
plish brown where bruised, stem equal or slightly thickened 
toward the base, straight or flexuous, yellow at the tof, 
reddish or reddish-brown below the annulus, sometimes 
varied with yellow stains, the annulus white or yellow, per 
sestent, forming a thick band about the stem; spores dvown- 
ash-ochraceous, .0004, to .00045 in. long, .coo16 to .0002 
broad. 
Pileus 2 to 5 in. broad; stem 2 to 5 in. long, 4 to 9 lines 
thick. 
Mossy or grassy ground in woods or open places, especially 
under or near tamarack trees. New York, Peck. New 
England, Frost. 
This is apparently closely related to B. elegans, from 
which it differs in its thick persistent annulus, in its stem 
which is not at all dotted and in its longer and darker 
colored spores. Its smaller tubes and persistent annulus 
separate it also from 4. flavus. In the typical form the 
pileus is bay-red or chestnut color, but plants growing in 
open places generally have it yellow or reddish-yellow. It 
is mild to the taste and I have eaten it sparingly. It some- 
times grows in tufts.
