No specimen available

Even when you have a good idea of what this is, it still surprises me.

I believe this is a species novum Scleroderma. The upper peridium is reddish brown, with some scales yellowish. Sporocarp has a distinctive, large root-like extension that DOES NOT stain when broken from much deeper rhizomorphs. When the sporocarp is sliced through the base, within 30 seconds the base turns chrome-yellow! This obs. found with Quercus palustris.


Reddish upper peridium, cracking, some yellowish scales on top.
Close-up of pseudostipe base: pure white and extending underground at least 1.5 inches.
Gleba black with white veination. Upper peridium can stain cinnabar-red when slicd. Base stains bright yellow when sliced.
