Observation 20874: Boletus rex-veris Arora & Simonini

When: 2009-05-06

Collection location: Jenkinson Lake, El Dorado Co., California, USA [Click for map]

Who: Ron Pastorino (Ronpast)

No specimen available

These are mature specimens growing well above ground. The caps seem slightly more red than the ones I usually find early in the season that are semi-buried. The reticulation on the stipe is very faint but visible up close.

after all of the recent BAMS discussion about red/not red cap coloration, altho your mention of the red being redder than usual is duly noted.

your statement about exposed vs buried caps makes me think that exposed caps are the red ones; they just start out pale (B. edulis does too, and stays pale if it remains buried).
Perhaps the reason that an inordinate amount of pale capped ones are found commercially is due to folks harvesting young buttons specifically? In other words, deliberate slection for the more pale, immature forms.
