Umbilicaria hyperborea

Ciri dan struktur

Thallus 2-5(-10) cm diam., monophyllous, but occurring with secondary lobules over the umbo and appearing polyphyllous, rigid to thin and pliable, umbo moderate to elevated, smooth to wrinkled or subgranular. Upper surface undulate or uneven, covered with a pattern of narrow, vermiform ridges extending to margins, in between ridges thallus appears darker, margins entire to unequal, rounded or lacerate, sometimes squamulose, surface dull to subnitid, greenish- grey, dark brown, greyish- brown or olive-brown. Lower surface bullate to lacunose, rarely plane, smooth to granular, grey-brown to brown-black, rhizines absent. Apothecia common, 1-2 mm diam., sessile, scattered almost to umbo, usually developed between ridges, free, circular to irregular, disc black, convex, regularly gyrose. Hymenium to 85 µm tall. Paraphyses simple, septate, rarely branched colourless. Hypothecium 140-160 µm thick, brown, irregular. Ascospores colourless 6.6-19.8 × 3.3-8 µm.

Habitat dan peran ekologis

The lichen typically grows on rock in arctic and alpine climates. It has, however, been recorded growing on acidic wood; specimens found in this substrate may have an altered morphology compared to those found on rock, such as stunted and faded thalli lacking apothecia. It is one of the most common Umbilicaria species in Arctic and adjacent Northern locations. Umbilicaria hyperborea has a very slow growth rate; in a study undertaken in Greenland, it was measured as 0.3–0.4 mm per year over the time period 1933–1970.
