Collemopsidium sublitorale (Leight.) Grube & B.D. Ryan

in Nash & al. (eds.), Lichen Flora of the Greater Sonoran Desert Region, 1: 163, 2002. Basionym: Verrucaria sublitoralis Leight. - Lich. Fl. Great Brit.: 435, 1871

Synonyms: Pyrenocollema sublitorale (Leight.) R.C. Harris

Distribution: C - Tosc.

Description: Thallus crustose, endosubstratic and usually not evident. Perithecia scattered, black, 0.15-0.6(-1.5) mm in diam., clearly projecting, globose or subglobose, often slightly flattened at the top, often with a crater-like periostiolar zone. Involucrellum well-evident, brown-black, hemispherical or spreading laterally; exciple colourless to pale brown in upper half, paler in lower half, more or less cellular; hamathecium of richly branched and anastomosing, 1.5-2 µm thick pseudoparaphyses, the hymenial gel I-. Asci 8-spored, cylindrical to subcylindrical, usually stalked, with two functional wall layers, K/I-, the wall thickened above, with an ocular chamber, fissitunicate, with a distinct extruded rostrum at dehiscence. Ascospores 1-septate, hyaline, narrowly ovoid, one cell usually longer than the other, (12-)15-22(-25) x 5-7(-10) µm, often with a thin gelatinous sheath. Pycnidia black, immersed or semi-immersed, flattened at top, the conidiogenous cells cylindrical, phialidic. Photobiont cyanobacterial (Hyella, the cells orange, in scattered clusters), or absent. Spot tests: all negative. Chemistry: without lichen substances.

Note: a maritime species growing on calcareous rocks, shells and barnacles in the littoral zone. Prior to 1992 it was treated as a synonym of C. halodytes, so that its total distribution is still poorly known.
