Abstract
An Elaphomyces species parasitized by Tolypocladium sp. was observed in Itako, Ibaraki Prefecture, central Japan. Based on morphological observations and molecular identification using nuclear ribosomal DNA sequences of both Elaphomyces and Tolypocladium spp., the present fungus and its parasite were identified as Elaphomyces fuscus and Tolypocladium japonicum, respectively. We report E. fuscus as a first record outside the type locality and as a new host of T. japonicum.
要旨
茨城県潮来市において、トリポクラディウム属菌が寄生したツチダンゴ属菌の一種が観察された。本菌ならびにトリポクラディウム属菌のそれぞれについて、形態的特徴の観察および子実体より得られた核リボソームDNA の塩基配列を用いた分子同定を行った。その結果、本菌はゴマタマツチダンゴElaphomyces fuscus、寄生していたトリポクラディウム属菌はタンポタケモドキTolypocladium japonicum とそれぞれ同定された。ゴマタマツチダンゴを基準標本産地以外から初めて記録するとともに、タンポタケモドキの新宿主として報告する。
