I didn’t propose a name because there are three possibilities then; P. isidiigera, P. enteroxantha and P. leucoleiptes. Even P. detersa may be a (distant) possibility. It’s way easier to identify P. perisidiosa with its distinctive little reflexed, splayed tips. (When it actually bothers to do that! Some specimens of perisidiosa are pretty ambiguous.)
