Obryzum |
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]
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]
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]
