Observation 72698: Pyrenula macrospora (Degel.) Coppins & P. James
When: 2011-07-07
Collection location: Sintra, Portugal [Click for map]
Who: zaca
No herbarium specimen

Notes: Matches very well with the short description and photos given in Irish lichens for Pyrenula macrospora. The distoseptate spores observed agree with those presented in bioimages for this species. I obtained the following values for their dimensions:
(24) 26.7 – 34.3 (36.6) x (9.4) 9.8 – 12.1 (13.9) µm
Q = (2.3) 2.5 – 3.2 (3.7) ; N = 24
Me = 30.8 × 10.9 µm ; Qe = 2.8.
Another very similar photo can be found in aphotofungi.
