Cladonia corymbites Nyl. , in Polakowsky (1877: 225)

( Fig. 3f View FIGURE 3 )

Primary thallus persistent to evanescent, laciniate squamules, esorediate, epruinose; podetia common, 1–2 cm tall, phyllopodiate, unbranched to slightly divaricately branched; axils closed with age, but in young podetia often open; tips blunt, ascyphose; surface mostly ecorticate, cortex restricted to the base, densely covered with microsquamules, often intermixed with macrosquamules along the length of the podetium, esorediate, egranulose; pycnidia and apothecia not seen.

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

Distribution and ecology: Currently know only from Floreana Island ( Ahti 2000); apparently a rare species, but possiby overlooked amongst morphologically similar taxa, known only from the humid highlands, on thin soil over rock, rarely as epiphyte.

Notes: Cladonia corymbites can be confused with C. cartilaginea , but that species forms only very few microsquamules and its macrosquamules are always restricted to its base. In contrast, C. corymbites is typically densely covered with both micro- and macrosquamules along the entire length of its podetia.

Cladonia corymbosula is another very similar species, but it forms podetia that are densely sorediategranulose and always lack microsquamules. Unlike C. corymbites , both C. cartilaginea and C. corymbosula are not phylopodiate, i.e., their squamules are persistent and not gradually being transformed into podetia.
