Histologic examination of crowns from circular areas of wilting Merion Kentucky bluegrass (Poa pratensis) and annual bluegrass (P. annua) revealed hyphae with clamp connections in the cortical tissue. The wilting grass plants occurred in patterns similar to those described for Fusarium blight of turfgrass. Basidiomycetes may play a role in the development of symptoms resembling Fusarium blight in turf.
