Observation 64399: Tephrocybe Donk
When: 2011-03-15
Herbarium specimen reported

Notes: Growing in douglas fir duff.

Spores mostly non-amyloid but with fine amyloid ornamentation.

Pleurocystidia looks like cheilocystidia and is usually deeply embedded in the gill. Type A: Harpoon shaped and filled with tiny (.25 micrometer) green dots. Type B: Narrowly clavate, sometimes with a rounded apex. Type C: Clavate with a narrow elongated apex.

Proposed Names

-50% (4)
Recognized by sight: If there really is amyloid bumps on the spores and the cheilocystidia are really harpoon-shaped, although I have a hard time seeing that from the microphotos. Macromorphology is very off, too.
-15% (3)
Recognized by sight
Based on microscopic features: Bumps on ellipsoid spores suggest something Clitopiloid, but they shouldn’t be amyloid. Also cheilocystidia are rare in that group.

support Tephrocybe very well in my experience

this is almost exactly what Tephrocybe palustris looked like under the scope

Yeah Tephro looks close…
