Thx for explanation of P. highandensis group

It’s very helpful. And (as you’ve probably seen) I added the explanation to that MO Name, and also created the MO Name P. subsaponaceus (and deprecated it, following the convention of Matheny (2018).

it appears from Matheny that we’re (currently) down to just four N. Amer. burn Pholiota — the ones in the title Matheny (2018)1. (Other names have been synonymized with one of those four.)

The burn-loving Pholiotas form a group

of species that have not been easy to differentiate from one another. I used the P. highlandensis group name to refer to several similar species that occur in burn areas—P. brunnescens, P. carbonaria, P. castanea, P. fulvozonata, P. highlandensis, P. molesta, and P. subsaponacea—because there isn’t always enough information to be more specific than that.

It’s nice that there is a recent study of this group which will help us get to species with more confidence.

Pholiota highlandensis Not likely: P. highlandensis has thin stem (often < 4mm); P. brunnescens and P. molesta have thicker stem. Compare image 952547 with Fig. 3 of Matheny (2018)1.

P. brunnescens Promising, P. molesta Doubtful: P. brunnescens has brunnescent stem (see image 952547); P. highlandensis and P. molesta do not.

P. highlandensis group Doubtful. Doesn’t resemble P. highlandensis; MO Name “P. highlandensis group” is not defined; and I don’t know what N. Amer species other than P. brunnescens, P. castanea, P. highlandensis, and P. molesta are in that group.
