Computer-aided morphometrical analysis of macroconidia in Fusarium sambucinum Fuckel sensu lato strains.

Forty-one strains of Fusarium sambucinum Fuckel sensu lato were classified on the basis of morphological data of the macroconidia obtained by automated microscopic image analysis. The classification factors were determined in six Fusarium strains of the section Discolor. The results show the relative homogeneity within the groups proposed by Nirenberg. A remarkable difference could be detected especially between the groups F. sambucinum, F. torulosum and F. sambucinum sensu lato on the one hand and F. spec nov. on the other.
