description: <i>Cladonia</i> aff. <i>ramulosa</i> (With.) J.R. Laundon (1984: 225) (Fig. 6a) <i>Primary thallus</i> persistent, of ascendant and crenulate squamules, esorediate, epruinose; <i>podetia</i> common, slender, whitish gray or greenish gray sometimes with brown areas but not necrotic, elongate; 0.6–4 cm tall, simple; axils close; tips initially blunt but soon developing into narrow, very irregular, shallow and typically proliferating scyphi; <i>surface</i> mostly corticate but with small denuded areas; patches of the cortex flaking off as microsquamules, these eventually disintegrating into ecorticate soredia, typically becoming densely sorediate, but lacking corticate granules; <i>pycnidia</i> not seen; <i>apothecia</i> with brown jelly. <i>Spot tests and chemistry</i>: P+ red, K−, C−, KC−, UV−; fumarprotocetraric acid. <i>Distribution and ecology</i>: Currently known from Isabela, Pinta, San Cristóbal, and Santa Cruz; common throughout the humid zone, on soil or rock, often among plant debris and bryophytes. <i>Notes</i>: Specimens of <i>C.</i> aff. <i>ramulosa</i> can be extremely similar to <i>C. pulverulenta</i> and poorly developed specimens cannot always be identified with certainty; see the diagnostic differences discussed there. Although <i>Cladonia ramulosa</i> s.str. was reported by Ahti (2000) for South America, it may generally be questioned whether this species even occurs in this continent as preliminary molecular studies suggest that most South American specimens previously identified as <i>C. ramulosa</i> actually belong to at least one, possibly several distinct, yet still undescribed species. <i>Selected specimens examined</i>: ECUADOR.
