Recognized by sight: I used the http://www.svims.ca/council/Phaeoc.htm key and the closest match, as far as I can tell are pleurocystidiata. It’s say the occur mostly from (February–May) but I found them a few days ago, I could be wrong.

“More or less central, less than or equal to 90mm above ground level, combined length with pseudorhiza greater than 200mm.” – Phaeocollybia of the Pacific Northwest North America, by Lorelei Norvell and Ronald L. Exeter.

Debbie has questioned the “white” gills. From the above source: “Lamelae – Initially whitish to pale orange buff, cinnamon-colored when mature, aging to rusty brown.”

Your right, Debbie.

There is another thing that bothered me about these: the stipe is about 1/6 above ground (apparently) and 5/6 below ground. P. rufotubulina should be smaller or equal to 140mm above soil level, and less than 180mm below ground. Lamellae are described as “Initially pale orange cream (apricot, ochraceous buff), maturing to foxy bown (clay color, tawny) with bright rusty orange streaks.”

My source also states: “However, new (although still preliminary) sequence data (Matt Gordon, 2009 unpub. data) cluster P. californica and P. rufotubulina as one species that is well separated from P. scatesiae. If complete molecular analyses do support this recent inference, we intend to declar Pl. rufotubulina a synonym of P. californica. In the interim, we retail the species as independent in this book.”

It continues: “P. rufotubulina appears to be coastally restricted to Humbolt, Mendocino, and Marin Counties in California, while P. californica ranges north from Humboldt County in California to Benton County in Oregon.” Benton County is just west of Linn County, where this obs. is recorded from. Lebanon is about 22 miles from Corvallis, which is in Benton County.

not rufotibulina…

caps not red/orange enough, young gills here are white not pale orange.

rufotibulina also grows in clusters…did these?

cool phaeo tho…whatever sp. it is.

they all have those weird rooting stipes and usually conical caps, and they have kind of a slick greasy or slimy feel, and muted colors.

Do you remember where you found this, Maynard?

Would be nice to get a voucher collection for OSU Herbarium.

If this was proven to be P. rufotubulina

it would be a dramatic expansion of the currently-known population, which is from 12 locations in northern California.

is correct here. Galerina are small, usually wood-inhabiting fungi with short stipes ending in wood or sometimes grass.

Phaeocollybia “…is a genus of brown-spored agarics easily recognized in the field by their deeply rooting cartilaginous stipes and normally viscid conic-campanulate pilei.” — Phaeocollybia of Pacific Northwest North America, by Lorelei L. Norvell & Ronald L. Exeter.
