Laetiporus portentosus

Beech whiskers

A white, spongy polypore of Australia, New Zealand and southern South America that grows high on eucalypts, southern beech and hutu. It decays heartwood and was used for centuries as slow-smouldering tinder. It is not known in cultivation, so home growing is experimental.
