The conidia are produced on annellide conidiogenous cells. Each successive conidia that is born elongates the conidiogenous cell with scars resembling rings. Unlike phialide-like Deuteromycetes, the cell walls of the conidium and conidiogenous cell are contiuous.
Mostly found in soil and plant materials, this member of Deuteromycota can also be harmful to immunocompromised humans. It has also been associated with human deaths by producing Arsine gas when in contact with an old wallpaper dye from the 1810’s. A garlic smell is an indicator of this fungus in wallpaper; but this means the toxic fumes are already at a harmful concentration. One of the most popular dyes was Schweinfurter green. The fungus eats the starch in the wallpaper paste and converts arsenate to trimethylarsine oxide, which reduces to trimethylarsine.
