Obryzum is a fungal genus in the monotypic family Obryzaceae, in the class Sordariomycetes. The relationship of this taxon to other taxa within the class is unknown (incertae sedis).[3][4]

The genus name of Obryzum is derived from the Ancient Greek word ὄβρυζον‎ meaning pure gold.

Reported as a parasitic on cyanobacterial lichens from the genus Leptogium.[5][6]

Description

The genus is mainly lichenicolous but with green algae on rocks or tree bark and seldom on mosses. Sexual morph: Ascomata perithecial, pyriform (pear-like), astromatic, immersed. Ostiole periphysate. Peridium hyaline with ostiolar region appearing light brown at times. Asci 4-8-spored, unitunicate, clavate, closely ellipsoid to ovoid, short-pedicellate, with barely visible apical ring, deliquescent at the base. Ascospores overlapping 1–2-seriate, hyaline, aseptate, smooth-walled, fusiform to limoniform or ellipsoid, lacking any mucilaginous sheath or appendage. Asexual morph is undetermined (adapted from Cannon & Kirk 2007, Maharachchikumbura et al. 2016).[7][8]

Distribution

It is mostly found in the north temperate zones,[5] and scattered worldwide. With most sightings in North America and Europe, with a few in Australia.[9] Such as Obryzum corniculatum is found in several places in Great Britain.[10]
