title: Rosellinia compacta, a new species similar to the white root rot fungus Rosellinia necatrix.
abstract: Rosellinia compacta is described as a new species that was discovered during a study of variation in Rosellinia necatrix in Japan using morphological and molecular characters. Rosellinia necatrix stromata and ascospores were 0.92-2.43 x 1.16-1.98 mm (mean 1.75 x 1.57 mm) and 30.5-55.9 x 5.0-10.3 microm (mean 41.8 x 6.9 microm) respectively. Rosellinia compacta had smaller stromata (1.13-1.71 x 0.99-1.36 mm; mean 1.43 x 1.16 mm) and longer ascospores ([34.0-]44.2-62.5 x 5.0-10.9 microm; mean 52.2 x 7.5 microm) than R. necatrix and also differs from other described species of Rosellinia.
