Student's Hand-Book of Mushrooms of America, Edible and Poisonous

Excerpt: ...The plants of the genus Trametes allied to Fomes are epiphytal, with the trama the same in substance and color as the hymenophore. The tubes do not form in regular strata, but are sunk into the substance of the pileus. The plants are coriaceous, and none are edible. Daedalea closely resembles Trametes with the tubes forming deep labyrinthiform depressions. Whole plant woody, sessile. Hexagonia, allied by its characteristics to Polystictus, has large hexagonal pores, with firm, entire dissepiments. In Favolus the plants are slightly fleshy and substipitate with the pores angular, and radiating from the stem. Not edible. Pg 3-12 The species of the genus Laschia are recognized by the shallow irregular pores and the vein like character of their dissepiments (or pore walls). Substance slightly gelatinous. In the plants of Porothelium, irregular papillae take the place of tubes, and the plants are sub-membranaceous and resupinate, having the habit of those of Poria. The genus Merulius has been termed the lowest and most imperfect of the genera of Polyporei. It presents a soft, waxy spore-bearing surface, reticulated with obtuse folds. Solenia, by early authors placed in Discomycetes, thence transferred to Auricularini, and by some authors associated with Cyphella in Theleporei, now finds place as one of the genera of Polyporei as given by Saccardo. The above-mentioned genera, together with Myriadoporus, Ceriomyces, Bresadolia, Theleporus, Gl
