Description: Original observation #49284 (Mushroom Observer)
Occurrence Remarks: Boletus sp. This looks to me like what people in the Northstate Mycological Club, based in St. Germain, which is about 50 miles North and West of where we were collecting, call 'Jana's bolete'. It was identified by Nancy (Smith) Weber, who once visited this club, as Boletus sphaerocystis Smith and Theirs, which was seen once in Ann Arbor by Smith, and published in their 1971 monograph. I did not, however, check these for the sphaerocysts of its name. It looks like subglabripes. Cap 5.5 cm, stem x11 mm at apex. 'Jana's bolete' is very common in the St Germain area, and eagerly sought for eating by the club members. They do not do microscopy on it.
