Collection location: Howarth Park, Santa Rosa, California, USA [Click for map]

Who: Debbie Drechsler (debdrex)

No specimen available

Found at the base of a dead oak next to a large mahogany polypore which was new last season. The surrounding area is a fairly open oak woodland with blue oak predominating. The gills are the same color as the pilei and travel a bit down the stipe. They are sturdy feeling, neither slimy or dry, but somewhere in between. The one on the left is 6 cm high and the pileus is 2 cm wide.


The same group a little over a month later. The largest is 23 cm across.

Thanks, Nathan. It makes sense now that you’ve said it. Sadly they’re not in a place where I can go looking at night.

Young specimens often have small caps and large stipes like that. The orange color with olive undertones growing at the base of a dead tree are all good characteristics for this species. They look a bit young to glow in the dark, but it’s fun to try to see the effect.
