Pannaria globuligera
Description : Thallus orbicular, distinctly foliose, to 8 cm diam., closely to loosely attached centrally, margins ±raised and free. Lobes 3–4 mm wide, 250–350 μm thick, peripheral lobes radiating. Upper surface dark-bluish or blue-black when wet, pale-fawnish when dry and then distinctly wrinkled (×10 lens), margins with crowded, bluish, globular lobules, partly decorticate. Apothecia rare, marginal, sessile, 0.5–2 mm diam., disc plane to convex, yellowish to red-brown, thalline margin prominent, crenulate. Ascospores narrowly ellipsoidal, 15–25 × 7–8 μm.
Chemistry : Thallus K−, C−, KC−, Pd+ orange; containing pannarin and terpenoids.
N: Northland . On coastal mangroves. Known also from East Africa (Swinscow & Krog 1988: 152– as P. fulvescens; Jørgensen 2003a), Hawai'i, Korea, Japan, the Philippines, Norfolk I., New Caledonia and NE Australia (Jørgensen & Kashiwadani 2001a: 4, fig. 6; Jørgensen 2001b: 119; McCarthy 2003c, 2006).

Pannaria globuligera is characterised by: the corticolous habit; the foliose, radiating, orbicular thallus that is attached centrally with margins feee and ascending; a distinctly wrinkled upper surface, with characteristic globular, partly corticate lobules at the margins; and pannarin as the major secondary compound.
