Observation 69420: Lecanora Ach.
When: 2011-06-17
Who: zaca
No herbarium specimen

Notes: Does this belong to the group lecanora L: leprosa, L. helva, L. ochroa, which are characterized by having an amphithecium with algal cells? The morphological and chemical tests coincide as well. However, the distribution of these species, although it is very wide, does not include any part of Europe, according co CNALH.

Most Lecanora have algae in the amphithecium

Definition of “Lecanorine” according to Bruce Ryan:

LECANORINE, LECANOROID pertaining to an apothecium containing algae at least below the hypothecium and usually having a distinct amphithecium that often also contains algae, as in the genus Lecanora; often used in a broad sense that includes zeorine, cryptolecanorine, etc.

While we’re at it, since I just discovered I had that definition subtly wrong all this time…

AMPHITHECIUM (usually), thalline margin of an apothecium; Hertel (Calcifer Lecidea) uses it for the part of the proper excipulum in the margin outside of the parathecium.

According to Sonoran Flora generic description:

…Apothecia: immersed or sessile, constricted at the base or not; disc: variously colored, epruinose or pruinose; margin: usually containing algal cells, generally conspicuous and concolorous with the thallus, in some species inconspicuous, reduced or becoming excluded; amphithecial cortex: present or absent…

So I’m afraid we can’t narrow down this observation very far on this information! :)
