Observation 23223: Tuber P. Micheli ex F.H. Wigg.
When: 2009-07-15
No herbarium specimen

Notes: Identification suggested by Dr. Michael Castellano, who actually found the sporocarp shown. He also suggested it might be a Macowanites, but I see no stipe or columella present, which usually is present in Macowanites.

Tuber should have venae externae (external veins). The closest thing to that here that I can see is a mid-line canal through the entire sporocarp. In addition, there appears to be small holes on the right-hand side. Caz said he thought it might also be a Macowanites. But Macowanites would have a distinctive cap area, which is also lacking to my eye on this specimen. Without an interior, it’s impossible to say anything further. But I’d suggest this is more likely a very immature Gymnomyces, possibly G. brunnescens. In Latin, brunnescens means “becoming brown” or “bruising brown” which, does seem to match the peridium here, at least.
