Description:
Diagnostics: The diagnostic features are the white basal mycelium, the cyanescent lamellae and flesh that turn grayish, and thin-walled non-incrusted hymenial cystidia. Phylloporus cyanescens has longer spores and stronger, cyanescent flesh when compared to P. bellus. The molecular phylogeny does not support a similarity based on the collections included in the analyses, since var. cyanescens is positioned in a different clade from the two collections of P. bellus var. bellus. Singer (1978) conjectured that var. cyanescens could be P. foliiporus, a species from southern USA and Japan, and not a variety of P. bellus. However, the cystidia of var. cyanescens are longer and not melleous at the apex as in P. foliiporus. The molecular phylogenies based on LSU and ITS genes also separate these three taxa.
Registration number: MB 563627
Distribution: Malaya, Australia
Ectomycorrhiza: In Australia, occuring in forest of Eucalyptus regnans, Nothofagus cunninghamii. Possibly with Fagaceae in Malaya.
Commentary: Elevation of var. cyanescens to species rank is warranted based on the morphological differences among the three taxa and on the phylogeny provided by the LSU and ITS analysis.
