When: 2011-06-23

No herbarium specimen

Notes: On the same tree of the specimens considered in MO70328 lived this one, which I think is the fertile version of the species.
Here are the dimensions of the spores observed:
(13.3) 16 – 20.6 (22.6) x (6.3) 7 – 8.8 (9.7) µm
Q = (1.6) 2 – 2.6 (3) ; N = 55
Me = 18.2 × 7.9 µm ; Qe = 2.3.
