Ocellularia fumosa (Ach.) Müll. Arg.

Ocellularia rimosa Hale

Thallus corticola, brunneo- vel viridi-cinereus, epiphloeodes, nitidus, continuus sed aetate rimosus, usque ad 15 cm latus; apothecia numerosa, emergentia, 0.7–09 mm diametro, apice obfusca, columella nulla; ostiolum rotundum vel irregulare, 0.1–0.2 mm diametro, nigrocinctum; hymenium 110μ–150μ altum; sporae 8:nae, transversim 6–8 loculatae, 7μ–10μ × 24μ–32μ, I+ coerulescentes (Figure 12b).

CHEMISTRY.—No substances present.

HOLOTYPE.—Base of tree in primary rain forest, Dleau Gommier Forest Reserve, Dominica, elevation 370 m, Hale 37978, 1 December 1971 (U.S.).

HABITAT.—Prop roots, tree bases, and lianas in rain forest (370–430 m).

Except for chemistry and slightly larger apothecia, this species is very close to O. nigropuncta, new species. Both are base level species, but O. rimosa has a more restricted elevational range. The two species were collected together only at Dleau Gommier.

SPECIMENS EXAMINED.—11 (38052), 16a (37654), 16b (37392, 37803), 16c (37758).
