putredinis

Monodictys S. Hughes, Can. J. Bot. 36: 785 (1958)
Type species: Monodictys putredinis (Wallr.) S. Hughes

Asexual morph: Hyphae septate, branched, thin-walled, hyaline to brown or fuscous. Conidiophores hyalines to sub-hyaline, septate, simple or sparingly branched, 8-200 x 1.5-6 μm. Conidia dark brown to fuscous, basal cell hyaline, muriform, pyriform, oblong ovoid, spherical, slightly constricted at the septa, 20-28 (-44) x 16-24 μm. In culture the conidia are more variable in shape and larger. (Descriptions based on Jones (1963)).

= Piricuada articoceanourm R.T. Moore, Rhodora 61: 95 (1958)

Asexual morph: Hyphae septate, rarely branched, dark brown or fuscous. Conidiophores short or lacking, cylindrical, zero to two-septate, simple, lateral, dark brown. Conidia 15-41(-44) μm × 12.5-37 μm, obpyrifrom, ovoid or rarely subglobose, muriform, not or slightly constricted at the septa, smooth, black, with one to three yellowish or light brown basal cells, solitary, the septation is only visible in immature conidia. Chlamydospores 48-155 μm × 6.5-21 μm, dark brown, intercalary, catenulate, composed of 4-25 cells, chains simple, rarely muriform. Sexual morph: Nereiospora cristata, see this website. (Descriptions based on Pang et al. (2011)).

SUBSTRATA: saprobic on driftwood, intertidal wood, dead mangrove wood, test panels, Juncus, Spartina, Typha.
