An ascomycete with non stromatic, narrowly ovoidal or subpyriform, pale yellow to luteous perithecia, a Nectria-like centrum, yellowish-brown reticulate ascospores, and a Trichothecium-like anamorph has been isolated from small rodent dung in Italy. Based on morphological, cultural and molecular (nrLSU and ITS sequences) data, a new genus, Rodentomyces, and a new species, R. reticulatus, are therefore introduced to accommodate this fungus. Rodentomyces represents a hypocrealean genus in the Nectriaceae. Within this family, and based on molecular data, R. reticulatus is placed in the group including Calonectria, Leuconectria, Nectricladiella, Neonectria and Nectria mariannaeae. Several coprophilous genera are recorded in Hypocreales almost evenly distributed among the main families of this order.

Abstract
An ascomycete with non stromatic, narrowly ovoidal or subpyriform, pale yellow to luteous perithecia, a Nectria-like centrum, yellowish-brown reticulate ascospores, and a Trichothecium-like anamorph has been isolated from small rodent dung in Italy. Based on morphological, cultural and molecular (nrLSU and ITS sequences) data, a new genus, Rodentomyces, and a new species, R. reticulatus, are therefore introduced to accommodate this fungus. Rodentomyces represents a hypocrealean genus in the Nectriaceae. Within this family, and based on molecular data, R. reticulatus is placed in the group including Calonectria, Leuconectria, Nectricladiella, Neonectria and Nectria mariannaeae. Several coprophilous genera are recorded in Hypocreales almost evenly distributed among the main families of this order.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
