Typhula ishikariensis is, along with Typhula incarnata, the causal agent of Grey Snow Mould (also called Speckled Snow Mould or Typhula Blight), a plant pathogen that can destroy turfgrass when covered for a long period with snow. It is a particular problem on golf courses established in unsuitable areas.[1] More importantly, it can also damage crops of winter wheat.[2] The species was described as new to science in 1930 by Japanese mycologist Sanshi Imai.[3] The varieties canadensis and ishikariensis (the former as a new combination) were described in 1978.[4]
