Flora of New Zealand Series

Description : Basal squamules persistent, inconspicuous, 1–2 mm long, 0.5–1 mm diam., incised, margins crenate. Podetia arising from basal squamules, (15–)20–40(–55) mm tall, 1–2.5(–4) mm diam., subcylindrical or tapering to apices, simple or branching somewhat near apices, branching forming deformed scyphi, axils closed; surface corticate at base and below apothecia, remainder of podetia ecorticate and densely farinose-sorediate; without squanules or with squamules on lower parts of podetia. Apothecia rare, red, terminal.

Chemistry : Cortex K+ yellow, KC−, Pd+ yellow; containing thamnolic, barbatic and didymic acids.

N: Wellington (Hihitahi State Forest, Waiopehu Tararua Ra.). S: Nelson (Mt Owen). Canterbury (Mt Cassidy, Arthur's Pass), Otago (N branch Routeburn), Southland (Seaward Bush). C: On dead wood or soil containing fragments of dead wood. Known also from Australia, Papua New Guinea, the Solomon Islands, South America and the subantarctic islands (Archer 1985a, 1992b; Stenroos 1993; McCarthy 2003c, 2006) including the Falkland Is (Stenroos & Ahti 1992) and Antarctica (Øvstedal & Lewis Smith 2001).

Cladonia weymouthii is morphologically similar to C. macilenta but is distinguished by the occasional deformed scyphi and the tall, branched, partly corticate podetia. It is separated from C. corniculata by the absence of fumarprotocetraric acid.
