Coccocarpia delicatula Bungartz, Ziemmeck & Lücking

liquen concha, Shell lichen

Thallus foliicolous, foliose, rounded, up to 10 mm diameter. Lobes thin, flat, 0.1–0.2 mm wide, linear but slightly widened towards the apex, isotomically branched and dissected, rather close. Upper surface blue-green when moist, plumbeous to bluish grey when dry, with thin, longitudinal, white striae. Lower surface pale, with pale, unbranched, tapering, 0.2–0.4 mm long rhizines partly protruding from under the lobe margins and visible from above. Lobes isidiate; isidia laminal, dense, uniformly cylindrical, mostly unbranched to bifurcate, 0.1–0.3 mm long and 0.05–0.1 mm thick, in mature thalli covering most of the thallus interior. Apothecia not observed. Pycnidia not observed. Chemistry: no substances detected by TLC.

Closely relatd to Coccocarpia domingensis Vain. and the recently described C. neglecta Aptroot & Lücking (Lücking et al. 2007). All three species have very narrow, linear thallus lobes with fine, white longitudinal striae on the surface, and differ principally in the shape and arrangement of their isidia. InC. neglecta, the isidia are mostly marginal and rounded-squamiform, whereas C. domingensis has marginal, cylindrical to often slightly flattened isidia. C. delicatula produces laminal, always cylindrical isidia, identical to the type of isidia found in C. palmicola. The latter, however, has much broader, rounded thallus lobes.
