Abstract

The identity of mycorrhizal fungi associated with the achlorophyllous orchid Epipogium roseum was investigated by DNA analysis. The fungi were isolated from each coiled hypha (peloton), and the ITS region of nuclear rDNA was sequenced. Phylogenetic analysis based on the neighbor-joining method showed that all the isolates clustered with fungi belonging to Psathyrella or Coprinus in Coprinaceae. Those fungi are known as saprobes, using dead organic materials for a nutritive source. Large colonies of this orchid were frequently found around tree stumps or fallen logs. In such colonies, these decaying wood materials would be used as a large and persistent carbon source for the growth of this orchid. This is the first report of Coprinaceae as an orchid mycorrhizal fungi.
