Who: Matthew Schink (MSchink)

No specimen available

Specimen kindly sent to me from Florida for study. Growing in woodchips. I suspected T.colossus from the photos, and confirmed via microscopy due to massive spore size and presence of chlamydospores.

Spores average 17x 10.9µm Qe= 1.6 Very large for Ganoderma spores.

Is fairly tropical, especially when you get onto the bit between the Atlantic and the Gulf. Most of the Gulf states are at least subtropical in climate I think. Very warm and very humid. Recently Amauroderma a tropical Genus is the Ganodermataceae was reported from Florida for the first time. I had suspected as much as I have seen people posting specimens that looked like Amauroderma from Florida for years but could never get someone to send me one.

Indeed tomophagus i always suspected it was just a tropical polypore. While i know that florida is hot i never suspected to be a tropical climate.
