Index Fungorum number: IF 28536; Facesoffungi number: FoF 08109, 1 morphological species (Species Fungorum 2021), molecular data unavailable.
Saprobic on host. Sexual morph: Ascomata superficial, solitary to gregarious, or partially grouped, uniloculate, globose to subglobose, elongate or ellipsoid, conchate or shield shaped, small to medium sized; apex cristate, opening by longitudinal slit; surface black, smooth, shining sometimes longitudinally striate. Peridium thick, composed of dark-brown cells of textura globulosa. Hamathecium comprising numerous, unbranched, aseptate, hyaline, filiform cellular pseudoparaphyses. Asci 8-spored, bitunicate, fissitunicate, cylindrical-clavate, sessile or sometimes with a long pedicel, with a beak-shaped apex, ocular chamber not well-developed. Ascospores fasciculate, elongate cylindrical or narrowly oblong, filiform, tapering towards narrow and rounded ends, multi-septate, hyaline, smooth-walled. Asexual morph: Unknown (Adapted from Vassiljeva 2001).
Type species: Zoggium mayorii (H. Zogg) Lar.N. Vassiljeva
Notes: Zoggium was introduced by Vassiljeva (2001) with Z. mayorii as type species. Zoggium mayori was previously described as Lophium mayorii on Pinus and Larix from the Swiss and French Alps, but it differed from other taxa of Lophium in having rigid, band-forming ascomata, with a less fragile peridium. Vasilyeva (2001) described the same fungus in the Russian Far East and confirmed that Lophium mayorii is characterized by erumpent crowded ascomata with ridge-like in appearance while species of Lophium are smaller, fragile, and forms entirely superficial fruiting bodies and transferred the species as Zoggium mayori. Zoggium is morphologically a distinct genus in Mytilinidiaceae but molecular data is needed to confirm this taxonomic placement.
