Cenomyce carneola Fr., Sched. Crit. Lich. Suec. 1–4: 23 (1825).

Description : Basal squamules persistent or evanescent, 2–3 mm long, 0.5–1 mm diam., irregularly laciniate. Podetia (3–)5–20(–50) mm tall, 2–4 mm diam., pale-yellow, cup-bearing; cups 2–9 mm diam., flaring abruptly, margins dentate; surface corticate at base, otherwise farinose-sorediate; soredia granular below cups and on inner surface of cups. Apothecia moderately common, 0.5–5 mm diam., pale-brown. Ascospores fusiform, 12–16.5 × 3.5–5 μm. Pycnidia very common, dark-brown to black, conical to cylindrical, blunt to subacute, gelatine colourless. Conidia 3–4 × 0.5–1 μm.

Chemistry : Thallus K−, C−, KC+ yellow, Pd−, UV−; containing usnic acid and accessory barbatic, and isousnic acids and zeorin.

S: Otago (Maungatua), Southland (Fortrose, Longwood Ra. summit). St: (Freshwater Valley). Recorded from collections made by Jack Scott Thomson in Zahlbruckner (1941: 325) and Martin (1958: 620).

Cladonia carneola is characterised by: the sorediate, pale-yellowish-green podetia terminating in broad, brown-rimmed cups; and the Pd− reaction, which distinguishes it from other sorediate, cup-bearing species.
