I am disappointed, Daniel. The species described has decurrent _pores_,
whereas Phaeocollybia, Oudemansiella and Amanita all have gills, which
also not decurrent.

Now this is an exciting possibility. Do you know the appropriate
authority on fungi? (In the UK it is Kew Gardens, who are always
to identify specimens.)
