Generic name for certain species of Fungi Imperfecti in which chains of conidia develop from tubular structures that form as the result of a constriction at the end of each of a series of short hyphal branches; close septations divide the contents of the tube into relatively square, thick-walled, deeply staining segments that eventually separate and become rounded, thick-walled spores with rough surfaces.
