Usually fleshy, somewhat umbrella-shaped, when stalked, or fan- 

 shaped when sessile. Consists generally of a stalk, termed the 

 stipe, bearing at its apex a large circular expansion, the pileus 

 (hat). On the underside of the pileus are a number of radiating 

 plates of tissue (lamellse) on which are developed the microscopic 

 basidia. Pileus and stalk yb^vj much as regards size, shape, 

 consistency and colour. 



Habitat. — On the ground, amongst moss, on trunks, rotten 

 wood, dead leaves. 



Collectors ought to take notes regarding the following points : — 

 Whether the pileus is furrowed or even, viscid or dry, .convex 

 or plane, umbonate in the centre or depressed, pubescent or scaly 

 or smooth, ciliated on the margin, of what colour and size ; whether 

 the stalk is viscid, hairy, striped ; colour of the lamellae. 



2. PolyporaceSB. — ('poly^many, porus^pore, hole). The Dry 

 Rot of timber is caused by members of this family. (Plate I, D ; 

 Plate II ; Plate III, A, B ; Plate IV, A.) 



Plants of all possible shapes ; fleshy, cartilaginous, or tough like 

 wood, forming thin crusts, shapeless lumps, or umbrella-shaped 

 like Agarics, or with the stalk-less pileus reflexed. They differ, 

 however, from the Agarics by bearing the basidia not on radiating 

 lamellae, but in alveolar (honey-comb-like) pits or tubes. 



Hahitat. — On rotten wood, branches, stumps (seldom on living 

 trees), or on the ground. 



Characters to he noted. — Colour of pileus and tubes ; surface even 

 or striped.
