Abstract
Ectomycorrhizal fungi, especially basidiomycetes, have repeatedly evolved from saprotrophic ancestors. Using rDNA internal transcribed spacer and large subunit sequences, we demonstrate that four species of Coltricia and Coltriciella form ectomycorrhiza with the native Vateriopsis seychellarum (Dipterocarpaceae) and Intsia bijuga (Caesalpiniaceae) as well as the introduced Eucalyptus robusta (Myrtaceae) in Seychelles. Coltricia and Coltriciella species share a thin, orange-brown to dark brown mantle and extremely thick, clampless hyphae. Phylogenetic analyses placed Coltriciella monophyletic within Coltricia. This study provides further evidence that fruiting habit on dead wood does not indicate saprotrophic lifestyle.
