Xylographa soralifera Holien & Tønsberg

Rare species, circumscribed only recently. Distinguished from ecologically and morphologically similar X. vitiligo by the presence of fumarprotocetraric acid, usually less pigmented and more protruding convex soralia, and partly episubstratal thallus (Holien & Tønsberg 2008). When sterile, might be difficult to distinguish from unrelated lichens with similar chemistry (e. g. Pertusaria pupillaris) which, however, differ in their ecological preferences. Xylographa soralifera is only known from few specimens from the Šumava Mts and Český les Mts where it occurs on hard wood of lying logs in natural mountain forests.
