Distribution.

New to Norway. Tephromela grumosa has been expected to occur in Norway, as it is known from a number of provinces in Sweden and Finland. It occurs in West, Central, and North Europe and in Asia ( Lambley and Purvis 2009). The species is rather closely related to the type species of the genus, T. atra (Huds.) Hafellner & Kalb, but it is always sorediate and rarely fertile (Fig. 13 ). In contrast to the genetically very heterogenous T. atra s. lat., T. grumosa seem to be genetically rather consistent compared to its morphology (Muggia et al. 2008, 2014). The species is furthermore separated by their chemistries, i.e., by the presence of lichesterinic acid in T. grumosa . The chemistry of the Norwegian specimen was confirmed by TLC. According to Muggia et al (2008) T. grumosa is a cooltemperate species found on steeply inclined, acidic siliceous rocks. In the locality in Norway, luxuriant, partly fertile specimens grew on steep faces of a large boulder in a stabilized S-facing talus. The rock is schistose, and probably somewhat calciferous. The locality is situated in one of the driest areas in Scandinavia, with an annual precipitation of c. 350 mm. In other habitats, e.g. on hard, granitic rocks in coastal heath on the Swedish west coast, specimens of this species are much thinner and less prominent.
