Gonatobotryum sp.

Mitosporic fungus. Hyphomycetes.

Gonatobotryum species are common in certain ecological niches. They are parasitic on Ceratocystis, and so are found where Ceratocystis is found, most particularly lumber. Most homes built with lumber have areas of growth of both Ceratocystis and Gonatobotryum on wood framing inside walls. (Virtually all lumberyards have some percentage of boards with areas of this black mold growth.) No information is available regarding health effects or toxicity. Allergenicity has not been studied. May be identified on surfaces by tape lifts, tease mounts from bulk samples, and in air by spore trap samples. (Spores have distinctive morphology.) Other natural habitats include soil, and rotten wood. Also parasitic on certain other plants.
