Collected by Crissy Ditty on a group hunt. 5 fruiting bodies were growing out of a hole in the ground near Tsuga canadensis, Pinus strobus, Fagus grandifolia and Quercus sp. Possibly other trees as well. Caps slimy. Younger caps were a deeper brown. Taste acrid but not strongly. Odor indistinct. Stems dry with pruina toward the apex.

What is this?!

On small dead birch trunk in wet mixed forest. Looks like thin, pink pie crust has been slapped on this sapling! ID is just a guess based on images online. Hydnoporia corrugata may also be a possibility?

"Resupinate, odontioid, cream to ochraceous. Monomitic, hyphae with clamps. Two kinds of cystidia: 1)Hyphoid, tubular with globose apex, thin walled, strongly constricted, 2) lagenocystidia, narrower in the needle apical part, encrusted terminal part. Basidia clavate to cylindrical with a median constriction, 4 sterigmata, and a basal clamp." Corticiaceae by Annarosa Bernicchia.

On conifer forest, sometimes around stumps, or at the edge of the stump itself. Or on buried roots of shrubs around creeks, in within the conifer forest.
Velvety, dark, fleshy (1.5 cms. over center). Only slightly depressed on the center. The length of the stipe varies, I think that depends on how deep the attachment to the buried wood, or root is.
About 5 pores per mm.
Spores (7.7-9.0) x (3.3-4.0); Ave Q=2.24, cylindric.

Resupinate spongy polypore growing on Atlantic white cedar. Pine Barrens. Swampy area. 1 1/2-3 pores per mm. Margin fribrose and delicate. Pale yellow inside pores. On the second sample there are powdery areas. Basidia: 19.7-27 x 4.9-5.1 um. Hyphae with clamps and thick walls: 2.7 um.

Collected along the Blackbird Knob trail. Growing on a Picea rubens stick near Betula alleghaniensis, Fagus grandifolia, Acer spp., and Picea rubens. Co-occurring with Phanerochaete sp. DG2308124. Not fluorescing under 365 nm UV light.
