Resumo: 	The Pink Disease is caused by Erythricium salmonicolor, which attacks broad hosts, such as citrus, coffee, rubber, Eucalyptus spp. and Acacia spp., infecting mainly branches. This disease became a serious problem in Brazil, reducing the citrus production up to 10%. However the genetic diversity and compatibility of the fungus E. salmonicolor from Brazilian citrus plants is not yet evaluated. Therefore, the aims of this study were to evaluate: i) the genetic variability of E. salmonicolor in the São Paulo and Minas Gerais States by the RAPD technique, and ii) the vegetative compatibility between these isolates. After RAPD analysis, six distinct groups were observed without correlation between the isolation site or host species. In the vegetative compatibility test, the contact of fungal hyphae between all evaluated crosses was observed, of which 84% presented hyphal fusion. Although the compatibility between strains was observed, no correlation between RAPD haplotypes and hyphal anastomosis was verified. These results show the importance of future studies on the sexual cycle of E. salmonicolor, since hyphal fusion, which precedes the formation of heterokaryons (sexual and parasexual reproduction) that could be responsible for the genetic variability in this species.
