Observation 75302: Physcia clementei (Sm.) Lynge
When: 2011-09-03
Who: zaca
No herbarium specimen

Notes: According to the reference given this non-ciliate species differs from the similar P. aipolia among others in the chemistry and in the dimensions of the spores. I obtained the following the following values for the spores:
(14.5) 15.6 – 20.5 (23.8) x (6.5) 7.2 – 8.4 (9.2) µm
Q = (1.9) 2 – 2.6 (3.4) ; N = 37
Me = 18.3 × 7.7 µm ; Qe = 2.4.

In fact, all the data agree with my previous observations (in particular, MO70329 and MO70676).
Thanks, Jason, for the correction.

Did you consider P. clementei? I know of no other pustulate species of Physcia, and it seems to be common in Portugal. P. stellaris never has soredia.
