Brief description
Characterised by very broad rounded lobes (it has the broadest lobes of any species in Notoparmelia); conspicuous, discrete, pseudocyphellae; bacillar conidia; and a faintly greenish cast to the upper surface.
Distribution
North Island: Gisborne (Lake Waikaremoana), Wellington (Waipakahi Valley, Pongaroa, Manawatu). South Island: Nelson (Tophouse) to Southland. Stewart Island.
Known also from South East Australia, including Tasmania.
Habitat
Widespread as an epiphyte of Fuscospora, lowland to subalpine. It is the largest Notoparmelia in the beech forests of the South Island, and at forest margins the large rosettes are visually arresting. It is rarely if ever found on twigs, and appears more common in the forest of the South Island, than in those of the North Island, where it is frequently replaced by N. erumpens.
Detailed description
Thallus thin and papery, orbicular to spreading, often in very large rosettes to 20(-40) cm diam., ± loosely attached, corticolous, very rarely saxicolous. Lobes broadly rounded (5-25 mm wide) or slightly elongate-imbricate, margins rounded, entire, with a fine, black or brown shining rim, occasionally developing crowded lobules centrally. Upper surface smooth, rarely faveolate-cracked centrally, shining, undulate, greyish-green, not darker at margins, often with a bluish tinge, pseudocyphellae small, white, sigmoid, scattered evenly over upper surface, often minute and crowded at lobe margins but not forming a reticulum of white lines. Lower surface black, smooth with a narrow, brown, naked marginal zone, rhizinate centrally. Rhizines black, sparse to numerous, simple to squarrosely branched. Apothecia common, pedicellate, to 15 mm diam., disc plane or subconcave, matt, reddish-brown to yellowish-brown, greenish-blue in shaded specimens, often centrally perforate, margins entire, thalline exciple smooth, shining, concolorous with Thallus, maculate or pseudocyphellate. Ascospores ellipsoid, 14-16 × 8-12 µm.
Chemistry: Cortex K+ yellow; medulla K+ yellow→red, C−, KC+ red, Pd+ orange; containing atranorin, chloroatranorin, salazinic acid (major) and consalazinic acid (minor).
Similar taxa
Similar to N. signifera but that species has denser, reticulate pseudocyphellae; bifusiform conidia; and often a brownish cast to the upper surface. Also, N. tenuirima is corticolous whereas N. signifera is saxicolous.
Substrate
Corticolous
