Abstract

Thick walled hyphae of polypores react in cresyi blue with a wide variety of colours, not only according to the species involved, but also according to the provenance of the dye used. In most cases, the resulting colours are constant for a particular species although there are slight individual variations. In some of the genera investigated all or nearly all species reacted similarly, whilst in others rather wide differences in the manner of reaction occurred. These differences, taken with other characters, may indicate that taxonomical relationships inside a particular genus (e.g. Amyloporia, Piptoporus) are not as close as at present considered.
