Neopyrenochaeta annellidica is a species of saprobic, hyaline-spored coelomycetes found on submerged decaying wood in freshwater habitats.
Taxonomy The species was first described in 2020 in a study revising coelomycete classification based on morphology and phylogeny.
Description The sexual morph of N. annellidica is undetermined.
The asexual morph features conidiomata, the fruiting structures of coelomycetes. The conidiomata are black when dry, dark brown when moist, and feature a white conidial mass surrounding the ostiole. The primary identifying feature of N. annellidica is the presence of pycnidial ("flask-like") conidiomata. The setae are pale brown to black, unbranched, and septate.
PDA cultures range from white to pale gray with white, undulate margins, with a dark brown center and white margins on the reverse side.
Distribution N. annellidica has been described in Thailand, Vietnam and Spain.
Etymology The species epithet, "annelidica", refers to its annellidic conidiogenous cells, which are a type of blastic condidiogenesis cells in mycology.
