SUMMARY
Synchytrium aecidioides (Pk.) Pat. and Lagerh. on Psoralea mutisii from Ecuador is a long-cycled species and differs markedly from Peck's Uredo aecidioides or S. decipiens Farl. It is renamed S. lagerheimii sp. nov. and placed temporarily in the subgenus Microsynchytrium. In addition to S. lagerheimii, several other members of the subgenus Woroninella from other leguminous hosts are described, but they are not given specific names.
