Subbaromyces Hesselt
Index Fungorum number: IF5303


Sexual morph: Ascomata partially submerged, later superficial, membranous, syringe-shaped, beak divided into two portions by a large pronounced collar, with upper portion tapering to a small ostiole, surrounded by a fringe of hyphae. Paraphyses absent. Asci 8-spored, unitunicate, clavate, with autodigestible wall. Ascospores 2-celled, with cells of equal size, hyaline, surrounded by a gelatinous envelope, released as a mucus-like droplet at tip of perithecium. Asexual morph: Conidiophores branched, septate. Conidia hyaline, smooth-walled, asepate, exogenously formed, ellipsoid.


Notes: Subbaromyces splendens was repeatedly found growing on trickling filter beds in New York. Hesseltine (1953) reported both the sexual and asexual morphs. The genus is characterised by ascomata with ostiolar necks and 1-septate ascospores surrounded by a sheath. The asexual morph has micronematous conidiophores, with non-apically branching structures and solitary, holoblastic, oblong-elliptical to obovate conidia.
