 stratum ; hence homogeneous, the hymeniui,-^^^^ ^^^^ ven or a 

 little ribbed. The fornl is ariable, 

 from stipitate and funnel-shaped to 

 closely adnate and resupinate. It is 

 notable that in the majority of species 

 ^S^''^^^" ' ' "^"-'' // the spores are globose and rough, mostly 



\ // slightly coloured. We are disposed 



to place here the genus Lachnodadium, 

 which some authors include in the 

 Clavarieae, on account of the erect, 

 branched habit, resembling some species 

 of Clavaria, forgetting that there are 

 also erect, branching species of Tlicle- 

 pliora, to which these species of Lachno- 

 dadium are closely allied in texture rather than to fleshy 

 Clavariae. Stereum in form approaches Thelephora, but the 

 substance is firmer, more leathery, and the pileus has a distinct 

 outer stratum analogous to that in 

 Polystidus, with an intermediate 

 stratum, and a smooth, even hymenium 

 (Fig. 57). Closely resembling in 

 appearance is Hymenochacte, with the 

 exception that the hymenium is 

 velvety, with processes resembling 

 bristles. With the exception of Skep- 

 peria, in which the pileus is vertical, 

 most of the remaining genera are 

 wholly resupinate. These are : Conio- 

 phora, in which the effused substance 

 is 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 and 

 rather waxy, and the spores uncoloured ; Peniophora, with the 

 habit 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 added 

 the small genera — Aleurodiscns, with a somewhat saucer-shaped
