and I do not have room to save specimens for more than about a year unless someone makes a request during that time.

So, are you saying that it would be possible to find

T. elegans, which looks macroscopically like aesculi, in North America, but only in the southern tip of California, southern Florida, and the southern coastal region of Texas which have a neotropical climate?

his site and messiah college have a listing of aesculi/ gibbosa.

Elegans was first described in the Caribbean. it however can be found in tropical/neo tropical and sub-troipcal regions. the ids from Taiwan,China Mexico and south of Mexico are most likely accurate.

Well, I am sure glad you are working on

a polypore book, Michael. There is still a lot of confusion and contradictory information out there. For example, MO still shows T. elegans observation’s from China, Canada, Vermont, West Virginia, Wisconsin, and Pennsylvania (definitely not tropical locations) as well as Puerto Rico, Brazil, Mexico, and your Ob from Taiwan. Additionally, Michael Kuo (on his mushroomexpert web site and in his book “Mushrooms of the Midwest) still identifies elegans as a species that is “widely distributed, but more common below the Great Lakes.”

Can’t wait for a definitive, up to date polypore field guide!

old Ob. It certainly is aesculi … a clear example at that. Not sure when elegans became the name reserved for the European species. Guess I should review all my old white polypore observations and bring them up to date. Thanks for your help.
