Could that tortuous long cell be a lactifer? It’s been useful to study the micrographs here. Thanks for them and the comments.
I haven’t scoped the collection yet but we have obtained the ITS and this sequence is unlike anything we have sequenced to date and unlike anything sequenced from Europe to date. It is probably closely related to Inocybe bulbosissima, a European species evidently associated with Salix and about which I know next to nothing, based on ITS similarities. The most closely related sequences (95% similar) are from samples of Kobresia (Cyperaceae) ectomycorrhizal roots taken from alpine meadows in the eastern Himalaya of China.
Your Blue Oak associate is part of the greater Inocybe rimosa complex but at present most likely lacks a name. A comparison with the Japanese literature is probably in order, but I have not done that yet. Brad Kropp, from Utah State, and I are in the works of documenting 8 species of the I. rimosa complex from Utah and Washington (five of which will be described as new, mostly from high elevation conifer stands or with Mountain Mahogany) and yours matches none of them.
Brandon wrote that it will be DNA analyzed soon.
