Pseudocyphellaria lechleri
Stictina lechleri Müll. Arg., Flora 66: 354 (1883).
Thallus ± orbicular, forming clumps, 5-10(-15) cm diam., ± loosely attached, terricolous or saxicolous. Lobes laciniate-elongate, 1-3(-5) cm long, 0.5-1.0 cm wide, narrower and ± canaliculate, ascending at apices, margins entire, with punctate, yellow pseudocyphellae, apices ± furcate or blunt or variously incised. Upper surface pale greyish-blue, reddish-brown at apices when wet and distinctly white-maculate (×10 lens), suffused reddish-brown, cinnamon-brown centrally, distinctly reticulate-faveolate, ridges sharp and well-defined, faveolae deeply lacunose, matt, slightly glossy at apices. Medulla white. Photobiont blue- green. Lower surface ± bullate, pale buff to dark red-brown, uniformly tomentose to margins, tomentum silky, pale buff to brown. Pseudocyphellae yellow, minute, punctiform, scattered, without a distinct margin, sunk in tomentum. Apothecia not seen in New Zealand material. Chemistry: Pulvinic acid, pulvinic dilactone, calycin, stictic, constictic, norstictic and salazinic (±) acids, tenuiorin and three unidentified triterpenes.
S: Nelson (Mt Technical) to Otago (Central Otago mountains). Subalpine to alpine in grassland, often beneath Dracophyllum, most common east of the Main Divide.
Austral
P. lechleri is a terricolous species of subalpine to alpine grasslands in South I. Lobes are characteristically inrolled and ± ascending, apices are often dark chestnut-brown or red-brown and shining, faveolae are strongly defined with sharp interconnecting ridges. It is distinguished from the corticolous P. maculata in these characters, from P. crocata in the lack of soredia and from P. neglecta in the lack of marginal isidia.
