that helps to explain the difference between T. gibbosa and T. elegans; " T. gibbosa and T. elegans are very closely related, but T. gibbosa typically is perennial and has an “old” section on the top in the middle. See http://mushroomobserver.org/5142?search_seq=775822 "

Walt, Do both species have flesh that turns yellow with KOH?

I know it’s true of T. elegans but can’t find any reference for T. gibbosa.
