Russula brevipes Peck
Rep. (Annual) New York State Mus. Nat. Hist. 43: 20. 1890.

Original diagnosis

Pileus at first convex and umbilicate, then infundibuliform, dry, glabrous or slightly villose on the margin, white, sometimes varied with reddish-brown strains, flesh whitish, taste mild, slowly becoming slightly acrid; lamellae thin, close, adnate or slightly rounded behind, white; stem very short, solid, white; spores globose, verruculose, .0004 to .0005 in. in diameter.
Pileus 3 to 5 in. broad, stem 6 to 10 lines long, 6 to 10 lines thick.
Sandy soil in pine woods. Quogue. September.
This species is related to Russula delica, but is easily distinguished by its short stem and crowded lamellae. The pileus also is not shinning and the taste is tardily somewhat acrid. From Lactarius exsuccus it is it is separated by the character of the lamellae and the very short stem which is about as broad as it is long. The spores also are larger than in that species. The lamellae in the young plant are sometimes studded with drops of water. They are not clearly decurrent. Some of them are forked at the base. The pileus is but slightly raised above the surface of the ground and is generally soiled by adhering dirt and often marked by rusty or fuscous stains. The plant grew in old roads in the woods where the soil had been trodden and compacted.
