Abstract

<p>Typhula maritima on coastal dunes in Ishikari and Yoichi, Hokkaido, northern Japan, is illustrated as a new species on the basis of morphology and molecular evidence. The sclerotia in the sand had mycelial strands that extended upward to support basidiocarps. Mycelial strands also connected sclerotia with plant tissues of the dunegrass Eylmus mollis Trin. Typhula maritima is psychrotrophic and halotrophic, and sclerotia floated on seawater for 1 week. These physiological characteristics are important factors for adaptation to the coastal dune environment. Inoculation tests indicated that T. maritima could grow on living E. mollis, but it was not pathogenic. The results suggested that this fungus was, at least, not an active pathogen in the coastal dune ecosystem. Ex-holotype is TH-AIST-Tm-1 (= NBRC 104266).</p>
