Collection location: Southeast Portland, Multnomah Co., Oregon, USA [Click for map]

Who: Daniel B. Wheeler (Tuberale)

No specimen available

Don’t recognize this. Hope someone else does. Growing near Quercus palustra (Eastern red oak). Cap irregular; stipe central; caespitose cluster (only 1 cluster found); gills smokey gray to whitish-gray when extremely young; total height 1.75 inches; cap width: gills free to adnexed (mostly free); cap umbonate; no veil/ring; caps growing is such close proximity to each other they have grown together; odor unpleasant (to my nose) radish-like. I’m thinking this may be a Collybia; but the gill coloration is all wrong.

Used references: Aurora, p. 182. I don’t believe this is actually T. terreum with the dark reddish-black stipe, but it keys out easily in Aurora to this point, so is probably a related species.

Creamy white spore print

Did a spore print of this collection yesterday. It is cream-colored, with just a hint of yellow in it.

Well taken, Douglas

Have just added 4 more photos, a little closer, with quarter for scale. Cannot see veil/ring with 10x glass. Cap does seem to be finely fibrillose and concentrically zoned: zones include grayish-brown near center; dark grayish-brown; then another ring of lighter grayish-brown near rim. Only the central section seems to have a lot of tiny fibrils under 10×. Am taking spore print now, but doubt I will be able to get photos of the spores with my 10x Sony Mavica.

Little brown job

For little brown jobs, really need more info… Spore color? Was it on any substrate? Even past that, probably going to need a good shot of the spores here too…

I’m not sure about no veil, there might be veil fragments on the margin, but it hard to tell with the photos being so low res.
