Abstract
A description is provided for Tubeufia cerea. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: developing on effete stromata of bark-inhabiting ascomycetes, especially members of the Diatrypaceae, probably also obtaining nutrition from the bark tissues. DISEASE: probably none, the fungus living saprobically on dead fungal tissues for at least most of its life cycle. No detailed studies of its biology in nature have been carried out. GEOGRAPHICAL DISTRIBUTION: widely distributed in the north temperate zone with a few records from the tropics. Recorded from Austria, Belgium, Canada, Guyana, India, Netherlands, Portugal, Russia, UK, USA (Florida, Illinois, Iowa, Louisiana, Maine, Maryland, Massachusetts, Minnesota, Missouri, Nebraska, New Hampshire, New Jersey, New York, North Carolina, Ohio, Vermont, Utah). TRANSMISSION: the ascospores are presumably air-dispersed and the conidia transmitted via water-splash, but there is no experimental evidence to support these suppositions.
