Isidia numerous and dense to rather sparse, superficial (also marginal), concolorous with thallus or darker, squamiform (entire or a little incised) or some more teretiform, when young ± globular (often they grow out still remaining on thallus, forming small accessory lobules as in C. crispum, see Degelius 1954 pp. 38, 284).

The phyllocladia are granulose, squamulose, yerrucose, Subfoliose or cylindrical teretiform in the different species, and are corticated, with photobiont stratum below cortex (Fig. 3.6). The teretiform phyllocladia have almost the same morphology as that of a branch of pseudopodetium.
