Isolation, morphological identification and pathogenicity of Cylindrocladium scoparium and C. clavatum isolates obtained from plants rhizosphere cultivated in Pernambuco State. Braz. J. Microbiol. [online]. 2004, vol.35, n.4, pp. 292-294. ISSN 1678-4405. http://dx.doi.org/10.1590/S1517-83822004000300004.
Twelve isolates of Cylindrocladium scoparium and 4 isolates of C. clavatum were obtained from the rhizosphere of various species of plants by baiting with Ricinus communis leaves. The isolates of C. scoparium developed conidia of 32-(45)-60 x 3 -(4)-5 µm, and pyriform to ellipsoidal vesicles. C. clavatum showed conidia of 36-(44)-49 x 2-(4)-6 µm and clavate vesicles. All isolates induced necrosis on leaves and hypocotyls of eucalypt seedlings, with varying expression of symptoms.
