. Introduction to the study of fungi, their organography, classification, and distribution for the use of collectors . the pileus has a distinctouter stratum analogous to that inPolystidus, with an intermediatestratum, and a smooth, even hymenium(Fig. 57). Closely resembling inappearance is Hymenochacte, with theexception that the hymenium isvelvety, with processes resemblingbristles. With the exception of Skep-peria, in which the pileus is vertical,most of the remaining genera arewholly resupinate. These are : Conio-phora, in which the effused substanceis membranaceous and smooth, with coloured spores ; Corticium,in which the effused substance is usually thicker and firmer,but without an intermediate stratum, the hymenium smooth andrather waxy, and the spores uncoloured; Peniophora, with thehabit of Corticium,hut with a velvety hymenium; and Hypochnus,with the habit and appearance of Corticmm, but with the sub-stance softer, floccose, and more lax, and the hymenium less com-pact, but still the spores are uncoloured. To these must be addedthe small genera—Aleurodiscns, with a somewhat saucer-shaped. Fig. 57.—Stereum hirsutum. hymenomycetes 143 pileus, and pec ..j.^Aties of structure which prohibit its unisonwith Corticium, Michenera, with a placentiform habit, a waxyJijmeniuE^, and pedicellate spores ; and Exobasidium and Helico-hasidium, which are encrusting and waxy, growing upon livingplants, and distorting them. Finally, Cyi^hclla, having the formof Feziza but the fruit of Corticium, being in fact a cup-shapedCorticium ; and Solcnia, the cups of which are elongated intotubes, so that it seems doubtful whether they should be placedin relationship with Poria, in Polyporeae, or with Cyphclla inThcleplioreac. Briefly and succinctly, these are the principal genera ofThclephoreae, but before dismissing them we must advert tocertain appendages of the hymenium whichdistinguish some of the genera aboveenumerated. In addition to the basidiathere are to be found in the
