Observation 219519: Tomophagus colossus (Fr.) Murrill
When: 2015-10-17
Who: MSchink
No herbarium specimen

Notes: 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.
