Nomenclature

Russula foetentula Peck
Bull. New York State Mus. Nat. Hist. 116: 85. 1907.

Original diagnosis

Pileus thin, nearly plane, viscid, glabrous, striate on the margin, reddish yellow, flesh white, taste tardily acrid, odor like that of almonds; lamellae thin, narrow, close, adnexed or nearly free, whitish, the interspaces venose; stem equal, firm, cavernous, white or yellowish white, usually spotted or stained with reddish brown at the base; spores very pale yellow, globose, .0003–.00035 of an inch broad.
Pileus 1.5–3 inches broad, the stem 1–1.5 inches long, 3–5 lines thick.
Among fallen leaves in woods. Suffolk country. August.
This species is related to R. foetens Fr., to which it is similar in odor but from which it differs in its closer lamellae and reddish brown or burnt sienna color at the base of the stem.
The species reported in State Museum Report 35, page 135 under the name Russula heterophylla Fr. are doubtful and the species is therefore omitted.
