Notes: <strong>Coccocarpia</strong> pellita is characterized by is flattened, squamiform isidia, as<br />
opposed to <strong>the</strong> cylindrical isidia in C. palmicola (ARVIDSSON 1983). In <strong>the</strong> material<br />
observed by us, we found two different types of isidia: semicircular and entire to<br />
marginally incised (Fig. 1F), and elongate-branched, resembling phyllidia (Fig. 1E).<br />
ARVIDSSON (1983) accepts this as variation within <strong>the</strong> species, which we follow here, but<br />
this matter requires attention since no such range of variation is observed in <strong>the</strong> o<strong>the</strong>r<br />
isidiate species of <strong>Coccocarpia</strong>.<br />

WIS – isotype).<br />
Thallus corticolous, foliose, starting as round colonies but eventually covering irregular<br />
areas of up to 50 mm across, with lobes in one to several planes. Lobes in first plane thin,<br />
flat, 0.2–0.4 mm wide, linear, isotomically branched, leaving interspaces, at lobe tips often<br />
multiply branched; lobe apices more or less ascending but tips curved downward and often<br />
bifurcate; lobes in second planes thin, irregularly ascending, 0.1–0.3 mm wide, linear,<br />
strongly isotomically branched and often radiating towards <strong>the</strong> lobe tips. Upper surface<br />
blue-green when moist, plumbeous to brownish or greenish grey when dry, with thin,<br />
longitudinal, white striae. Lower surface pale, with numerous white, unbranched, tapering,<br />
