Observation 200091: Phaeographis lyellii (Sm.) Zahlbr.
When: 2014-05-01
Collection location: Sintra, Portugal [Click for map]
Who: zaca
No herbarium specimen

Notes: Based on the distinctive features of this species given in observation 200090, quickly I was able to identify another specimen collected the same day in the same area. The photo is a bit out of focus, but no other available. This time there were plenty of new asci and spores. Here are some data from microscopy:
Hymenium tall: ~110 um
Spores dimensions:
(22.6) 24.4 – 28.4 (30.9) x (7.8) 8.1 – 9.5 (10.3) µm
Q = (2.3) 2.7 – 3.3 (3.4) ; N = 35
Me = 26.2 × 8.8 µm ; Qe = 3
Spores septation: 5, very few with less.

Relatively to observation 200090, to observe the variation in the Q factor, caused mainly by the increase in width, due to the existence of abundant mature (non-shrivelled) spores.
