When: 2012-10-25
Who: Byrain
Herbarium specimen reported

Notes: Spore range (20 measured) = 14 – 16 × 7 – 8 (9) μ
Average spore = 14.8 × 7.85 μ
Q range = 1.75 – 2.29
Average Q = 1.89
4-spored basidia observed
Basidia range (10 measured) = (25) 28 – 32 (38) x 9 – 12 (13) μ
Pedicel range (4 measured) = 4 – 5 μ
Epicutis cell width range (20 measured) = 25 – 40 μ
Epicutis cell width average = 31.85 μ
Cheilocystidia range (10 measured) = (25) 28 – 42 (45) x 7 – 8 (12) μ
Caulocystidia range (10 measured) = (31) 37 – 43 × 8 – 10 (11) μ

The smell is strongly farinaceous.
Most spores were without 1-2 oil drops, one observed section of a gill had a high concentration of immature spores with oil drops. The mature spores in the vicinity were lacking them.
Some basidia and basidioles were brownish in KOH, most were hyaline.
