"Polyporus frondosus
Polyporus frondosus forms similar large clusters as the Polyporus sulphureus, but whereas if P. sulphureus is the colour of fire. P frondosus is the colour of smoke. It arises like a phantom from humus at the base of old trees, a ghost bouquet, seemingly gauze-petalled, unsubstantial as mist, actually as heavy as a pumpkin; heavy enough to require a wheelbarrow for transport (for the mycophagist, well worth the effort; P. frondosus is said to be choice). As for P. sulphureus, its tender outer edges (considered similar to chicken), when trimmed off, will self-renew, providing more treats."
