Observation 22285: Hypomyces (Fr.) Tul. & C. Tul.
When: 2009-06-17
Herbarium specimen reported

Notes: I’ve never seen this before, so I am not very confident of the ID. Could also be Paxillus involutus. Pileus dark brown, smooth but dull, not shiny, somewhat like leather. Stipe strongly tapered to point at base. But for the dark brown color, I would have guessed this was a Chanterelle. Enlarged picture of gills will show what are apparently cross-veins. Found in grassy/mossy mostly open urban park with mixed hardwoods and evergreen. One other specimen was left for further observation with results to be posted as supplement. Spore print could not be obtained. Other mushrooms found very close by include red Russulas, green Russula (R. aeruginea?), some boletes with yellow pores included in picture posted here), and several Aminata specimens (A. vaginata and Aminita sp. observation discussed at 21306).

Supplemental observation on 2 days after date of collection of first specimen with new photos of specimen that was left for observation:

The apparantly similar specimen located proximate to first specimen collected turned out to look rather different a day later. The pileus had become cracked, and the pore surface was neither gilled nor having pores like a bolete, but instead apparently solid. Base of stipe stained red when injured. See pictures added. Pileus 2 inches, stipe 1 inch. Will attempt spore print and then will bisect for photograph.

you might try using an Identification Key authored by M.A. Neves who worked on the genus for her PhD. A link to a PDF of that key can be found at: http://www.nybg.org/bsci/res/hall/boletes. The Bessette et al. bolete book has 4 species in it.
The tubulose bolete could be B. innixus.

I have no doubt

about the genus Phylloporus, but there are a lot of species in there; it has not to be rhodoxanthus altho this seems to be the most frequent at least in the eastern part of the States. As for the bolete this clearly is not Boletus badius.
