Some data from microscopy:
Spores (measured at magnification 1000):
(8.8) 8.9 – 9.8 (10.3) x (5.3) 5.6 – 6.2 (6.3) µm
Q = 1.5 – 1.7 (1.8) ; N = 20
Me = 9.4 × 5.9 µm ; Qe = 1.6;

Pleurocystidia:
(52) 52.5 – 72.5 (76) x (14.7) 14.8 – 20.9 (26.2) µm
Q = (2) 2.5 – 4.3 (4.4) ; N = 14
Me = 61.6 × 18.7 µm ; Qe = 3.4

Cheilocystidia:
(48.8) 50.3 – 71 (75.5) x (9) 9.3 – 15.1 (16.8) µm
Q = (3.6) 3.7 – 6.7 (7.9) ; N = 21
Me = 61.6 × 11.7 µm ; Qe = 5.5

NOTE: The values given above show that the lenght of pleuro- and cheilo-cystidia are similar, but the latter are thinner than the former. It should also be remarked that at the base of cheilocystidia (many of them also metuloid like pleurocystidia) there are some basidiole-like structures, similar in dimensions to the basidia, that could also be cheilocystidia; these were not considered in the above measurements.
