Mycorrhizal associations can be considered required for orchids, which depend on the fungi for germination and establishment in natural conditions. Knowledge of the mycorrhizal fungi is important for programs aimed at the reintroduction, conservation and management of orchid species. The objective of this study was the molecular characterization of Rhizoctonia-like fungi from orchids in the Quadrilatero Ferr fero (Iron Quadrangle) and Zona da Mata (Forest Zone) regions of the state of Minas Gerais, Brazil. The affinities of these fungi were studied by comparing the rRNA internal transcribed spacer region with that of other isolates and sequences in GenBank. Three isolates had an affinity for Epulorhiza repens, and one was the holotype of E. epiphytica.
