The dark conidiophores produce a single apical spore (conidium) through a pore and then continue to grow through the pore, thus dislodging the spore. Successive periods of spore production and regrowth give the conidiophore a noded appearance. The spores are dark brown and are divided by several longitudinal and transverse walls. Occurring on decaying and living plants and in soil. Holomorphs: Leptosphaerulina, Pleospora. Ref: Ellis 1971
