The results of the microscopy are in accorsance with those given at “mushroom expert” for C. luteo-olivaceum, except that the spore didn’t turn red in KOH and in fact there was no change: in addition, the pilleipellis has at places some brown pigmentation and some fuzy golden cells are present in the gill trama (see the attached photos from microscopy).

Yeah,

the chemical reaction should be made with the fresh specimen, but I didn’t …
I have looked to the description of Callistosporium luteo-olivaceum and, macroscopically, this could be it. However, I will try to get data from microscopy in the near future.
Thanks, Claude, for your comment.

As regards the chemical reaction, I should have specified on a fresh specimen.
Did you look on the side of Callistosporium luteo-olivaceum?

Hi Claude,
I uploaded a photo displaying the KOH reaction on cap and gills, on the dried specimen. The reaction on cap was strong and purple; The reaction on the gill was very weak red (note that the gills became purplish on drying).

Do the hat and the blades become red in the KOH 10% ?
