Observation 217942: Lobothallia radiosa (Hoffm.) Hafellner

When: 2015-10-04

Collection location: Serra de São Mamede, Portugal [Click for map]

Who: zaca

No specimen available

Notes:
Growing on the stones of a fence.
When I saw these specimens almost seemed ridiculous!
At one stage of my learning lichens I found many specimens of Lobothallia (Aspicilia) radiosa almost always sterile (or with few apothecia) at another location. Thus, I could do anything but smile at the sight of these “conspicuously” fertile specimens. Naturally I will take the opportunity to do microscopy.

Unfortunately most of the sections were infertile, the others only with a few spores.
Spores:
(9.2) 9.5 – 11.5 (12.9) x (4.7) 5.4 – 6.7 (7.1) µm
Q = (1.5) 1.53 – 2.1 (2.2) ; N = 22
Me = 10.5 × 5.9 µm ; Qe = 1.8 .
