Ciri dan struktur
M. patagonica (Fig. 3) is morphologically similar to M. carnosa. Generally, spore characters are the best distinguishing characters (Fig. 4). The spores of M. carnosa are longer and 92% of 72 measured spores were in the range 23–35 µm. By contrast, 70% of 58 measured spores of M. patagonica were in the range 15–22 µm. This means that there is an overlap in sizes between these two species. However, the spores of M. patagonica are often two-septate, sometimes three-septate, which is very rare in M. carnosa. Here follows a more detailed treatment of Massalongia patagonica Kitaura & Lorenz: Thallus foliose, forming rosettes up to 3 cm, mostly muscicolous; lobes 0.5–1.5 mm broad, up to 1 cm long, irregularly and repeatedly divided with isidioid marginal outgrowths, simple to sparingly branched, sometimes developing into branched lobule systems, lobules, 0.1 mm wide. Upper surface brown, glabrous and glossy; upper cortex 20–30 µm thick, paraplectenchymatic, of thick-walled (ca. 1.5–2 µm wide) cells with 7–12 µm large lumina; photobiont layer 40–60 µm thick, often also developed in the subhymenium; cyanobiont Nostoc, cells bluish-green, irregularly subglobose to ellipsoid, 5–9 × 6–11 µm in size, arranged within 20–40 µm large glomeruli without visible chain structures, chain structures visible in some liberated cells; medulla loose, 60–80 µm thick; lower cortex absent, with scattered rhizohyphae. Apothecia common to scattered, substipitate, laminal, 1–2 mm wide; thalline excipulum lacking, true excipulum weakly prominent; epithecium 5–10 µm thick, of protruding brown and strongly swollen, pyriform paraphyse end cells, 4–6 µm wide, 7–10 µm long, paraphyses undivided to sparingly divided, 2–4 µm thick; hymenium ca. 60 µm thick, IKI + blue; asci clavate 50–70 × 10–15 µm, 8-spored, with distinct internal apical IKI + blue sheath-like structures, sometimes also with weak tube structures; ascospores narrowly ellipsoid, occasionally asymmetric, 1- to 2 (3)-septate, (13) 20–25 (28) × 5–7.5 µm.
Habitat dan peran ekologis
This is a species of wet to dry rock surfaces or boulders, usually growing in between mosses or on plant remains. It has a widely scattered distribution in South America, ranging from the temperate forests of south-central Chile, including the Juan Fernandez Islands and Patagonia, with two widely separated collections from southernmost Chile and Argentinean Tierra del Fuego. In addition, it is known from the Falkland Islands, Antarctica, mountains of SE Australia, where it is rare and from several localities in New Zealand.
