Holotype
NORWAY. Sør-Trøndelag: Oppdal municipality, Drivdalen, by the rapids in the lower part of the river Kaldvella, 62°17'N, 9°35'E, alt. 940–980 m, exposed rock face in the subalpine region. 23 July 1993, E. Timdal 7535 (O L-125!), TLC: rangiformic acid, norrangiformic acid, unknown substances.
Distribution
New to Sweden. The species was previously known only from Norway and Greenland (Haugan and Timdal 1994[1]). It resembles the more common Calvitimela aglaea (Sommerf.) Hafellner, but differs in forming white areolae (Fig. 4), slightly longer ascospores (11.5–17 × 5–7.5 µm; Haugan and Timdal 1994[1]), and in the presence of rangiformic and norrangiformic acids in the thallus. In Calvitimela aglaea, the areolae are usually pale yellow, the ascospores shorter (9–13.5 × 5–7.5 µm), and the thallus contains atranorin, bourgeanic acid, usnic acid (rarely lacking), and sometimes stictic acid (Haugan and Timdal 1994[1]). In Norway, the species grows on sun-exposed, more or less sloping rock surfaces, often where water is trickling or near rivers or waterfalls in the subalpine and alpine regions. The Swedish locality is a boulder in the alpine region.
