all that helpful information. I appreciate your taking the time to educated me in this area. I sure hope all these polypores can be sorted out definitely by DNA before I am too old to care:):)

Ganoderma resinaceum group is still an accurate ID, but G.sessile is a more accurate name. G.sessile is a member of the G.resinaceum complex that occurs throughout most of Eastern North America it seems. It can be recognized by its brown flesh,smooth spore type,and its habit of bleeding a yellow resin when the white edge is pricked or cut. Also copious production of chlamydospores in culture. All traits shared with G.resinaceum sensu stricto in Europe.

There are a few members of the G.resinaceum clade here in North America. More DNA evidence is needed to figure out just how many and their geographic distributions.

Thanks for the update, Herbert.
