Cladonia arbuscula subsp. boliviana (Ahti) Ahti & DePriest (2001: 500)  

( Figs. 1c–d View FIGURE 1 )

Primary thallus evanescent; podetia forming cushions, slender, whitish gray, up to 12 cm tall, sparsely branched; branching pattern anisotomic, dichotomous, rarely trichotomous, principal axes easily distinguishable; axils occasionally perforate; tips typically slightly brown; surface ecorticate, barely verruculose; algal clumps (glomerules) often observed on the surface of old podetia; pycnidia with hyaline jelly; apothecia brown.

Spot tests and chemistry: P−, K−, C−, KC−, UV−; all Galapagos material examined contains only usnic acid (chemotype II of Ahti 2000).

Distribution and ecology: Currently known only from a single collection from the humid zone of Isabela Island; forming lichen heaths in sunny, wind- and rain-exposed habitat among ferns ( Pteridium arachnoideum   , Pernettya howellii   , Lycopodium sp.   ).

Notes: The species is similar to C. confusa f. bicolor   , but that species differs by thinner, more densely branched podetia and a ramification pattern where no principal axes can clearly be distinguished.

The axil perforation observed in the Galapagos material of C. arbuscula subsp. boliviana   is not mentioned by Ahti (2000).

Selected specimens examined: ECUADOR.
