Character Abstract
Identification Comments:Based on Beyer & St. Clair (2004), who assembled the description from a variety of literature.<br>Apparent thallus squamulose to granular, often corraloid, greenish to grayish brown, formed of<br>cephalodia containing <i>Nostoc </i>cyanobacteria, surrounding large urceolate (deeply concave) dark<br>reddish brown apothecia. A true thallus with green algae (<i>Coccomyxa</i>) is reduced to a thin ring<br>around the apothecia. Apothecia and squamules have rhizines on the underside, which attach the<br>thallus to the substrate. Apothecia up to 10 mm diameter though rarely over 5 mm diameter in<br>most populations. Hymenium hyaline; paraphyses unbranched and coherent with the tips redbrown<br>and slightly thickened. Ascospores brown, 1-septate, 4 per ascus, huge, 30 50 X 18 <br>22 &#956; m, with a warted, furrowed surface. Occurring on mosses over soil (or rarely directly on<br>rock or soil) in areas that are nearly perennially damp, in arctic, alpine, or subalpine, calcareous<br>habitats. In the southwest, high altitude seepage sites with a cool, northerly or easterly exposure,<br>appear to be the primary habitat. See photos in Beyer & St. Clair (2004) and Brodo et al. (2001).
Subspecies Comments:
Lookalikes:This is a very distinctive species. The thallus is superficially similar to some species in the<br>Pannariaceae, but the apothecia are quite distinct from any in that family. The apothecia<br>resemble other members of the genus Solorina, but the thallus clearly differs as all others have a<br>much better developed true thallus and cephalodia are quite restricted.
