A previously unreported foliar blight of loblolly pine (Pinus taeda), caused by a binucleate Rhizoctonia solani-like fungus in the Ceratobasidium anastomosis group 3 (CAG-3), is described. Isolates of binucleate Rhizoctonia sp. causing loblolly pine foliar blight anastomosed with binucleate isolates from blighted seedlings of longleaf pine (P. palustris).
