Cladonia chlorophaea (Flörke ex Sommerf.) Spreng. (1827: 273)

( Figs. 2e–f View FIGURE 2 )

Primary thallus persistent, of small, compact squamules that easily erode and in some specimens remain only as a few corticate granules, rarely eroding into ecorticate soredia, epruinose; podetia common, grayish green, short; 0.5–1 (1.5) cm tall, always broadly scyphose and shaped like a cone, i.e., gradually narrowing towards their base; scyphi predominantly simple, very rarely proliferating; surface corticate only at the base, soon becoming completely decorticated; densely sorediate-granulose, the soredia generally of uniform size along the entire surface of the podetium; scyphus rarely with few corticate granules inside; old podetia commonly with large denuded areas lacking soredia; pycnidia hyaline; apothecia not seen.

Spot tests and chemistry: P+ orange red, K−, C−, KC−, UV−; fumarprotocetraric acid.

Distribution and ecology: Newly reported from the Galapagos Islands. Known from Floreana, Isabela, Pinzón, San Cristóbal, Santa Cruz, and Santiago Island; a common species in the humid and transition zone, rarely also in the dry zone; typically on the ground, often on plant debris or rotten wood.

Notes: The species can be identified by its abundant, granulose soredia of a more or less uniform size across its podetial surface. Cladonia subsquamosa is very similar but generally has farinose soredia of less uniform size interspersed with granules and microsquamules. At first glance the species also resembles C. pyxidata , which, however, generally has broader scyphi with a corticate surface disintegrating into corticate granules, not forming ecorticate soredia.
