Anisomeridium elegans R. C. Harris, sp. nov.
Thallo corticato, glauco, UV+ aureo, ostiolo eccentrico, ascosporis ovoideis, septis valde submedianis,
laevibus, 51-57 × 23-26 µm
Type. PUERTO RICO. Distr. Mayagüez: Maricao State Forest, just NE of Universidad Católica Estación
Biologica, along Hwy 120 at km 15.8, along trail on hill top, ca. 700 m, semi-dry forest, 5 Jun 1988, Harris
22280 (NY, holotype).
Thallus corticate, epiphloeodal, glaucous green, glossy, UV+ yellow (lichexanthone), sometimes weakly
so. Ascomata immersed, covered by thallus and only visible as a weakly raised bump, lageniform, 0.5-0.8 ×
0.4-0.5 mm; ostiole eccentric or lateral; wall entirely melanized or open below. Asci cylindrical to subclavate,
ca. 200-300 × 40-55 µm, with eight subbiseriate spores. Ascospores ovoid, slightly constricted at markedly
submedian septum, smooth, 45-57 × 18-26 µm; pycnidia not found.
Anisomeridium elegans is related to A. infernale and A. nemorosum with similarly corticate thalli, but
differs in size of ascomata and asci and in size and shape of ascospores.
Additional specimen. PUERTO RICO. As type, ca. 600 m, moist forest on slope with tree ferns and palms,

Anisomeridium foliicola R. Sant. & Tibell
This lichen is apparently often produces only its very characteristic pycnidia. Santesson and Tibell
suggested that they might be producing microconidia. From the size and shape of the conidia in Costa Rican
material distributed by Lücking, I consider them to be macroconidia. This would suggest that since ascomata
are rare, dispersal is via these macroconidia. It is also noteworthy that the pycnidia of A. foliicola have a well
developed periphysoid plug which apparently relaeases the conidia single file. A similar feature is described
for the possibly synonymous and therefore illegitimate pycnidial genus Compsosporiella Sanarkan & Sutton.
