Loxospora A. Massal.

Loxospora Ric. Auton. Lich. Crost.: 137 (1852).

Notes.

Three species, L. cyamidia (Stirt.) Kantvilas, L. septata (Sipman & Aptroot) Kantvilas and L. solenospora ( Müll. Arg.) Kantvilas (syn. Sarrameana tasmanica Vězda & Kantvilas), from the Southern Hemisphere have not been sequenced so far. However, they have ascospores similar in shape to other Loxospora spp. (although, in L. cyamidia and L. solenospora , they are rarely septate), asci with an amyloid apical dome and contain thamnolic acid (although L. solenospora may sometimes contain additionally gyrophoric acid or only the latter substance) ( Kantvilas 2000, 2004). Given the morphological and chemical similarities to the type species L. elatina and other members of Loxospora s.str., they are treated here as belonging to this genus. Loxospora isidiata Kalb (described from the Philippines) and L. ochrophaeoides Kalb & Hafellner (described from Madeira), introduced by Kalb and Hafellner (1992) and L. glaucomiza (Nyl.) Kalb & Staiger (described from Japan) treated by Staiger and Kalb (1995) are also treated as belonging to Loxospora s.str. due to the production of thamnolic acid.

The name Loxospora pustulata (Brodo & W.L. Culb.) Egan was applied to a common and widespread pustulose-sorediate crustose species with thamnolic acid that occurs throughout eastern North America ( Brodo and Culberson 1986; Lendemer and Noell 2018). The discovery of fertile material led to its being transferred to the genus Lepra Scop. as L. pustulata (Brodo & W.L. Culb.) Lendemer & R.C. Harris ( Lendemer and Harris 2017).
