Observation 72414: Lobothallia alphoplaca (Wahlenb.) Hafellner
When: 2011-07-03
Who: zaca
No herbarium specimen

Notes: These specimens were growing in a man made fence dividing properties in the field. The macroscopic description in CNALH for the species Lobothallia alphoplaca matches very well. Also the accompanying photos by S. Sharnoff are very similar to my specimens.

I was looking to the site catalogne and it is very similar. I think I have no further basis to decide, but I’ll propose also L. radiosa (subcircinata is considered there as a variety). Thanks.

puede tratarse de Aspicilia subcircinata (Nyl.) Coppins, para muchos sinónimo de L. radiosa.

to the description in CNALH we have at our disposal the photos by Stephen Sharnoff. I found some similarities between my pictures and some of those there, much more than with the other members of the genus Lobothallia (L. praeradiosa and L. radiosa). That´s why I proposed L. alphoplaca.

a los lóbulos terminales ya que es un talo crustaceo placoide.

plane to more often strongly convex or almost cylindrical => que los lóbulos terminarles son planos a más frecuente fuertemente convexos o cilindricos.

L. aphoplaca:

lobes: 3-5(-7) mm long, 0.5-1(-1.5) mm across, 0.5-0.7 mm or more thick, usually distinctly elongated, radiating and separate, sometimes ascending, often +imbricate, plane to more often strongly convex or almost cylindrical, +richly incised-lobed

You wrote: “squamules convex, very convex.” and in CNALH it is written: “areoles: up to c. 1 mm in diam., discrete, +round, plane or convex, becoming crenate-lobed, often mixed with +elongated lobes”, which is not the samething.

squamules convex, very convex. Pienso que no coincide bien con este especimen, aunque nunca ví todavía una L. alphoplaca.

in spite of the genus Lobothallia has only few species, I’m a bit confused with it. It seems clear to me that the first specimen that I found belonging to this genus is L. radiosa (see MO). In all the others posted here at MO (as well as in many other that I didn’t post) I have doubts. This is the case of this specimen, that seems a bit faraway from the initial one.
