This genus was established by Fries (1823) to accommodate Lophium mytilinum, cosmopolitan in the temperate zones and has been recorded from the Atlantic region (Zogg 1962Barr 1990b). Lophium is characterised by fragile, conchate hysterothecia, sometimes seated on a foot-like base or sessile directly on the substrate. The thin-walled scleroparenchymatous peridium encloses a basal hamathecium of narrow trabeculate pseudoparaphyses, with very elongate asci, each bearing one fascicle of transversely septate filiform ascospores, often spirally arranged (Boehm et al. 2009a).

Type species: Lophium mytilinum (Pers.) Fr., Observ. mycol. (Havniae) 2: 345 (1818). 

≡ Hysterium mytilinum Pers., Syn. meth. fung. (Göttingen) 1: 97 (1801).
