Original Papers


A new species ofChaetomium, C. umbratile, is described from Japan. The species is based on three specimens isolated from house dust samples in asthmatic patients' dwellings. It is characterized by long, wavy and irregularly branched terminal hairs, which are intermingled with short straight hairs, and nearly globose to broadly ellipsoidal ascospores with a slightly subapical or sometimes lateral germ pore.
