Description

on a piece of rotten wood in very wet (normally submerged) habitat.

Several individuals, superficially resembling miniature Lasiosphaeria ovina. Sporodochia pale gray, less than 0.5mm in width, scattered, conidial mass surrounded by an arachnoid net of small thin, dichotomously branched pale to brown hyphae. Conidiogenous cells containing many relatively long denticle, often in quick succession on the conidiogenous cell. Conidiogenous cells are hyaline

Conidia are aseptate, smooth, without appendages or visible sheets, somewhat allantoid and hyaline, they measure 6.5 - 9.5 X 2-2.5 µm.

Because of the arachnoid net surrounding the conidial mass and the conidia that are produced on denticles, the genus neta is the likely. Amongst the species, N. lignicola is easily reached using Castañeda and Heredia key (Mycotaxon 76: 132). N. tropicalis is also similar but have much more allantoid conidia.

also compare with N. patuxentica as seen here : https://www.inaturalist.org/observations/94171469
