Observation 129971: Panaeolus olivaceus F.H. Møller
When: 2011-04-04
(34.85° 84.88° 233m)

Notes: Stephen (Ιερονυμοσ) collection. Microscopy by Alan Rockefeller.

Original observation is # 64988.

Basidia with a median constriction. Cheilocystidia similar to Panaeolus cinctulus. I looked for pleurocystidia and didn’t see any.

Spores minutely roughened, with a large apical germ pore. Mounted in KOH.

Spore measurements:

12.1 [13.5 ; 14.5] 15.9 × 7.5 [8.5 ; 9.2] 10.2 µm
Q = 1.4 [1.5 ; 1.6] 1.8 ; N = 16 ; C = 95%
Me = 14 × 8.8 µm ; Qe = 1.6

P. olivaceus has cool green immature spores in H2O also.
