Comments: Mytilinidiaceae (earlier Lophiaceae) was drawn up by BISBY and M.B. ELLIS (1952), ZOGG (1962), DARKER (1963), SUTTON (1970) and BARR (1990b). Up till now Lophium mytilinum Pers.: Fr., L. mayori Zogg and L. elegans Zogg were accepted as the true members of the genus, all on conifers such as Juniperus, Larix, Pinus and Abies (ZOGG 1962, HAWKSWORTH et al. 1995). Some other species described as Lophium have been transferred to the genus Glyphium. Ascospores of L. igoschinae resemble those of L. mayori, but simultaneously its ascomata are distinctly smaller. The genus Lophium has conchate ascomata whereas species with dolabriform ascomata belong to the genus Glyphium (ZOGG 1962). L. igoschinae is the first species of this genus that has been found on non-coniferous substrata. Size of ascospores according to ZOGG (1962): L. mytilinum: (130-)170-250(-300) x 1-2(-2.5) ym, L. elegans: (200-)260-280(-300) x 2 ym, L. mayori: (60-)80-100(-110) x 3-4(-5) ym.
