Arthrobotrys oligospora is the most common and best-studied nematode-trapping fungus and a model organism for research on how fungi and nematodes interact. It lives as a saprobe in soil, dung and decaying plant matter, and when nematodes are present it forms sticky three-dimensional hyphal nets that catch and digest them. It has been studied as a biological control agent for crop-parasitic nematodes. For mushroom growers, lab work shows its growth is stopped by carbendazim and formalin, which are used on mushroom farms.
Not edible; a microscopic mould with no food use.
Never eat a wild mushroom based on a web page — confirm with an expert.
Mycology is an evolving science: names, classifications and safety information change as research advances. Entries are compiled from cited sources and reviewed, but may be incomplete or out of date — check the sources, and never rely on this library alone to identify or eat a mushroom.
