Observation 76257: Schismatomma Flotow & Körber ex A. Massal.
When: 2011-09-11
Who: zaca
No herbarium specimen

Notes: Here are some features of this specimen:
- Thallus crustose, corticolous, of a light color with rose tons; no isidia or soredia;
- Ascomata with rounded or elongate to irregular lirellae, imersed in a whitish stroma, raised from thallus;
- Disc widely open, with a granular brownish to black surface that occupies all the area of the stroma;
- Exciple carbonized;
- Chemical reactions: C-, K-, KC-;
- Asci clavate, with a variable number of spores, mostly maybe 8-spored;
- Ascopores: hialine, narrow ellipsoid, multi-septate – 3 to 5 septa observed – with the following average dimensions: Me = 28.6 × 5.2 µm ; Qe = 5.6 (N=30).
I think that all the data presented above and illustrated in the attached photos probably belongs to a species of the genus Glyphis (see CNALH). The best known and widely distributed from all over the world species of this genus is G. cicatricosa. I don’t think that my specimen belongs to this species, which in general has a different disc and the spores are more septate and bigger. However, in azoresbioportal a specimen is presented with small spores that are 5-septate.
I was not able to find any reliable alternative for this specimen.
