Abstract

<p> 日本新産のチャツムタケ属菌,<i>Gymnopilus decipiens</i> (ヤケノヒメチャツムタケ),について,北海道で採集された標本に基づき,形態的特徴の記載と図を添えて報告した.北海道産 <i>G. decipiens</i> は火山性ガスを含む高温の水蒸気が噴出する噴気孔周辺に発生し,子実体は小型で温和な味であることが特徴である.分子系統解析の結果, 日本産標本の核 rDNA の ITS 領域は,ロシア( ヤクーツク) 産 <i>G. decipiens</i> のものと完全に一致する塩基配列を有し,本菌がシベリアから北海道の亜寒帯にかけて連続的に分布することが示された.</p>

<p> The present study reports the identification of a newly recorded species, <i>Gymnopilus decipiens</i>, in Japan, along with a description and illustration of its morphological characteristics (based on a specimen collected from Hokkaido). The <i>G. decipiens</i> specimen collected from Hokkaido is characterized by its close proximity to fumaroles, which discharge highlyheated steam and volcanic gas, and its small basidiomata and mild taste. Maximum parsimony analysis of the nuclear rDNA internal transcribed spacer (ITS) region revealed that Japanese and Russian (Yakutsk) samples of <i>G. decipiens</i> possess identical ITS sequences, suggesting that <i>G. decipiens</i> is widely distributed throughout the subarctic region, including Siberia and Hokkaido.</p>
