Observation 109290: Flavoparmelia soredians

When: 2012-09-07

Collection location: Parque de Monsanto, Lisboa, Portugal [Click for map]

Who: zaca

No specimen available

This time I could find specimens of the two alikes of Flavoparmelia, F. caperata and F. soredians, on the same tree and I could appreciate the main differences between the two species, which in my opinion are:
- Lobes more round in F. caperata and more elongated in F. soredians;
- Lobe ends almost free (i.e. non-appressed) in F. caperata and very much apressed to the thallus in F. soredians;
- Soredia almost inexistent in this particular specimen of F. caperata, but I known that it frequently exhibit pustulas that degenerate into more or less granular soredia, and soredia powdery in F. soredians;
- Different chemical reactions (see the photos of my observations of the two species).


Chemical reactions (on thallus).
