Observation 3209: Boletus aureissimus (Murrill) Murrill

When: 1993-07-05

Collection location: Flemming Park, near Shreveport, Louisiana, USA [Click for map]

Who: Ron Pastorino (Ronpast)

Specimen available

Notes:
Distinctive but relatively rare southern bolete. For ID used Bessette and Roody’s “North American Boletes” as well as other web sources.

3-12-12; Found that I had dried and saved these. Checked spores with KOH. Spores ~ 11.2-14.5 X 4.1-5.0 microns, cylindric(Q ave = 2.80) to narrowly fusiform, and smooth.
They seem to still fit within the description for Boletus aureissimus (Boletus auripes var. aureissimus) although the cap surface seemed somewhat velvety or “finely tomentose” as reported for Boletus auripes.
