Perhaps it is worth mentioning

That most (not all!) of the photos of Callistosporium luteo-olivaceum on MO reinforce my expectation that yours (western or west coast) is different from ours (east coast). The eastern form is more delicate (of course!) waxy translucent – thin capped. But as Alan will be sure to point out they all turn bright read with KOH. Let’s see some sequences!

Didn’t mean to say your ID is wrong, was only trying to clean up the Agaricaceae Chevall. observations, ~2 pages worth of misidentified observations…

Old specimen

This mushroom is still Callistosporium luteo-olivaceum. It was seen by the mycologists at SOMA Camp in 2009 and the identity remained the same. It sat out on the tables for three days, handled by many and eventually photographed at the end of Camp. The photo documents an OLD specimen and the stipe shows the blackening caused by fingers touching it.

Fair enough, but in future when the photo color is off or misleading…

perhaps a note saying that the odd color is an artifact would prevent needless ID anxiety amongst we obsessive mycologists?! ;)

The specimen collected in Pt. Reyes also appeared slightly bluish, much like this one. It was hard to tell if it was green or blue or black.

Not blue

The blue looking part of the stipe is a stain from many fingers handling it over several days. It was not not blue, so the camera has added the blue tint. It is hygrophanous, changed color from the fresh look and very dried out.

the blue coloration is curious…

how does it fit into a species description for Callistosporium luteo-olivaceum? Do the spores match? does it redden in KOH? I’m not buying it…so convince me!
