STUDIES ON TELEOMORPH OF COLLE TO TRICHUM LIN DEMUTHIANUM
菜豆炭疽菌有性态研究

In low temperature storage one culture of Colletotrichum lindemuthianum (Sacc. et Magn.) Br. et Cav., the pathogen of bean anthracnose, only produced perithecia but not conidia. The morphology, cultural character and monoascospore culture of the fungus was studied and compared with allied species. The result showed that this ascogenous culture isolated from conidia was Glomerella lindemuthianum Shear. The ascospore infected bean leaves by antificial inoculation, and the sympton was the same as that of C. lindemuthianum. In reisolation of pathogen, anamorphic conidia was first produced in culture, but teleomorph recovered soon after for several generations. The fact proved that the fungs was homothallic. The alternation and relation between perfect and imperfect stages indicated that this fungus was a holomorph: G. lindemuthianum was the teleomorph of C. lindemuthianum which was the anamorph.
