Observation 158808: Galerina semilanceata (Peck) A.H. Sm. & Singer
When: 2014-01-16
Who: Byrain

Notes: Under Abies grandis, I’m not sure if this is growing from the duff, the moss below it or both.

Spores roughened, no plage.
Spore range = 9 – 11 × 5 – 6 µm
Spore average = 9.9 × 5.5 µ
Q range = 1.67 – 2
Q average = 1.81
20 spores measured.

Cheilocystidia measured = 22×6, 25×7, 26×7×4, 28×7, 28×7×6, 29×9, 31×7×4, 31×7×7, 32×6, 36×6×6, 38×7×7, 39×6×6, 41×5, 43×6×4, 54×7×6x4 µ
Pileocystidia measured = 24×6, 25×6, 32×6, 38×8, 43×4 µ
Caulocystidia measured = 37×8×8, 40×57, 68×10×11, 75×9×10 µ
No pleurocystidia or clamps observed.
4 and maybe some 2-spored basidia observed.
Pileipellis & stipe hyphae yellowish in KOH.

This seems to be in subgenus Tubariopsis, with the pileocystidia and little or no veil remnants this seems to be something around Galerina laevis or G. dimorphocystis, but I’m a bit confused which is a better fit.

ITS sequence

The quality of this sequence was very poor, and it took 30 minutes to pull the signal out of the noise. When I did, I found that this is a 100% match for two Galerina semilanceata sequences in GenBank.
