Collection location: Sebastopol, Sonoma Co., California, USA [Click for map]
Returned to the same location as Observation 3663 to dig up the base of that collection. Found several more within a meter from the first.
The pseudostipe is a bit long (2 or 3 times normal length) on these and it reddens when cut and exposed to the air. Both of these characteristics are not in the literature for this species. The peridium does NOT turn red, nor does the outside skin on the pseudostipe, but the context of the pseudostipe is quickly rufescent. One of the photos (seventh one down) shows the pseudostipe after it was red, then a fresh cut shows the real tissue color near the rhizoidal mass at the base.
