The forms included above as resupinate may also in some instances 
become reflexed. The sub-division must not therefore be regarded 
as absolute. 
Sub-genus. VELLTICEPS , Cke. 
Hymenium velvety with coloured flexuous hairs, usually collected 
in fascicles. 
This has an entirely different structure from either Hymenochcete 
or Peniophora. The slender flexuous hairs are collected in conical 
tufts, which grow directly from the substratum of the hymenium, 
and are persistent ; whilst the bodies in Peniophora and the setae in 
Hymenochcete are but slightly attached to the hymenium, and fall 
out readily when the hymenium is old. We have included these 
forms as a subgenus, under Hymenochcete , although with a pre- 
ference for considering them worthy of rank as a separate genus, 
equally with Hymenochcete and Peniophora. 
The smaller section, with the hymenial hairs scattered, 
approaches nearest to Hymenochcete. The larger section, with the 
hairs in fascicles, represents our idea of the subgenus.
