Popis: Sarocladium oryzae is a common plant pathogen causing rice sheath rot worldwide. Sarocladium attenuatum has been identified as one of the causal agents of rice sheath rot and was synonymized under S. oryzae. The analysis of 102 Sarocladium strains associated with rice in Taiwan, based on morphological features and multilocus molecular phylogeny, reveals that these two species are distinct and that two other species, S. sparsum sp. nov. and S. spirale sp. nov., can be identified. Sarocladium sparsum is phylogenetically closely related to S. attenuatum and S. oryzae and causes the same disease symptom in pathogenicity tests. Sarocladium spirale, a sister taxon of S. hominis and S. spinificis, is not pathogenic to rice. All strains of S. attenuatum and some S. sparsum strains show fluorescence emission ability under 365-nm UV light, while S. oryzae does not.
