Observation 102568: Diploschistes diacapsis (Ach.) Lumbsch
When: 2012-07-22
Who: zaca
No herbarium specimen

Notes: Should the place be called “The Lair of Diploschistes diacapsis”? The specimens were spread by all this location, a hill that ends with cliffs over the sea, sometimes in big concentrations (see the photos attached). The variety of lichens existing here is not so big, but this seems to be the appropriate place for some species to develop, for instance, Psora decepiens and Fulgensia fulgens, that were also spread in small concentrations by this location (see observation 102569 and observation 102570), and very well developed specimens of Squamarina cartilaginea (see observation 102571).

Some notes obout the characteristics of the specimens observed:
- Thallus rimose-areolate, rarely purely areolate, whitish but some with a ochraceous tinge, in general covered with a white pruina; The permanent humidity existent at the place give to some of them the appearence of the existence of a membranous cover;
- Apothecia in general urceolate, sessile and sometimes immersed in the thallus;
discs dark colored, greyish to almost black in some cases, epruinose to slightly pruinose;
- Asci mainly with 8 spores, but also some with less (4 or 6), submuriform with 3-5 tranverse septa and 1 longitudinal septum; Spores with the following dimensions: Me = 24.9 × 10.4 µm ; Qe = 2.4 (N=33).
