Odor: not recorded

Taste: not recorded

Fruiting Body: ~4cm in diam., fleshy except for a firm, partially rooting columella. Leading growth zone (above) white, cottony, soft, covering upper 1/3 of the sporocarp, not well differentiated from the fertile layer. Columella ~1cm thick at base, tapering beneath, context white with scattered, irregularly-globose pockets and concentric zones of gelatinous, translucent tissue, eventually splitting into numerous thin, radial branches of the same tissue type in fertile layer. Spore mass light brown to tan, somewhat stringy, sparsely pitted in cross section.


Columella: Composed of long, hylaine, bundles of thin-walled, sparsely-branching parallel hyphae up to 6.5μm in width. Most concentrated at base, branching into thinner and thinner bundles toward the peridium, undifferentiated throughout.

Spores: light brown in deposit, smooth, subglobose to broadly ellipsoid, inequillateral in side view, inamyloid, 1- or more-guttulate.

All tissues inamyloid. Medallion clamps abundant throughout.
