Who: Andrew S (AmatoxinAndy)

No specimen available

Growing in soil at bottom of a draw in the general vicinity of live oak, gray pine, and ponderosa pine.

This specimen was growing singly and unusually intact for similar observations in area.

Cap 14 cm diameter, tube length 1.5 cm, stipe length 13 cm, stipe diameter 3.5-5 cm. Slight bulge to stipe in bottom half, tapering again toward base. Cap surface viscid.

No blueing when cut or bruised.

Taste, raw: cap context tasteless; tubes mild, slightly onion-y

Leaning Suillus genus but can’t find similar Suillus species in references with such a long, whitish stipe. Stipe not as bulbous as usually pictured for B. edulis, but can’t rule out and don’t know what else to call it.


Good view of yellowish tubes/pores and somewhat forked top of stipe
White context in general with faint yellowing adjacent to tubes which was already present when cut
