I didn’t try to stain it. I need to get better about trying chemical tests.

KOH doesn’t stain the cap either?

ok, thanks. Will think about it. Everything is drying up. I had a hard time finding much. I thought at the time that the group looked like it was moving toward spent, even the immature caps.

They still could be aged

According to

Postmeiotic Nuclear Behavior in Lentinus, Panus, and Neolentinus
David S. Hibbett; Shigeyuki Murakami; Akihiko Tsuneda

Neolentinus has binucleate spores
