Who: Dave W (Dave W)

No specimen available

Dots on stipe small and pale.

A small area along the cap margin developed a blue stain. Not sure how long this took. I noticed this maybe half an hour after collecting the mushroom. I believe I have seen this type staining on S. granulatus in the past. obs 213984, obs 242799.

Ammonia: not much to note.
KOH: mauve-tinged gray on cap context and stipe surface.

Material was unfortunately almost completely infested with insect larvae. I did salvage a small piece of cap.


Top row KOH; bottom row ammonia.
