Snow mold fungus Racodium therryanum is phylogenetically Herpotrichia juniperi

Racodium therryanum is a snow mold causing snow blight and seed rot in conifers. The sexual stage of R. therryanum has not been found, however, it has been speculated that Herpotrichia juniperi, which causes brown felt blight, is the sexual stage of R. therryanum. In this study, we conducted phyloge...

Sumario:Racodium therryanum is a snow mold causing snow blight and seed rot in conifers. The sexual stage of R. therryanum has not been found, however, it has been speculated that Herpotrichia juniperi, which causes brown felt blight, is the sexual stage of R. therryanum. In this study, we conducted phylogenetic analysis using 28S large subunit (LSU) rDNA, 18S small subunit (SSU) rDNA, translation elongation factor 1-alpha (tef1), and RNA polymerase II second largest subunit (rpb2). Four isolates were identified as R. therryanum based on their morphological characteristics; together with two strains of H. juniperi, they composed a clade supported by high bootstrap and Bayesian posterior probability values. Therefore, we conclude that the snow mold previously described as R. therryanum is phylogenetically H. juniperi.
