status

 

* Buellia aff. pallidomarginata A. Nordin (2000: 79) .

Characterized by the whitish thallus reacting K+ deep yellow, the apothecia with a proper margin paler than the disc and the 3- septate ascospores, 13.0–19.0 × 5.5–7.0 µm, with weak septal wall thickenings and smooth to microrugulate spore walls. It differs from B. pallidomarginata s. str. by its smaller ascospores. The material is too damaged to confirm its identity with certainty. Buellia pallidomarginata is a corticolous, tropical species only known from Central India ( Nordin 2000) and recently collected in Thailand (own data).

Material examined: ― GUATEMALA. (E) Monterrico: E of village, nature reserve 'Biotopo Monterrico-Hawaii', coastal mangrove swamps, on Rhizophora mangle , 1 m, 13° 54.2' N, 90° 28.3' W, 5 July 2004, P. & B. van den Boom 33560 (hb. v.d. Boom).
