or perhaps Trichlomopsis sulfureoides, which reportedly has yellowish cap hairs.

Good suggestion Martin.

It appears that the east coast version of C. luteo-olivaceum is heavy on the luteo but lacking the olivaceum. The ones I found in Texas appear to be a tweener.
A drop of 5% KOH on the dried cap does seem to want to turn reddish with a little time.

How would you feel about an east coast version of Callistosporium luteo-olivaceum?


I don’t have a clear memory (of anything really) of a scaly cap, but they often fruit after or during a rain, are fragile, and short lived. KOH on the cap would give a clear indication.
