V. -SPORES BLACK. 
Gills dissolving into milky fluid. Coprinus (Pages 32 to 34). 
Gills decurrent. Cap with radial markings. Agaricus [ Psathy - 
relict ], (Page 15). 
The Pore -toadstools (Polyporeae) form a large class, several of 
which are here illustrated : — 
(A) With central stalk. 
Fleshy forms, tubes easily separated from cap. Boletus 
(Pages 35 and 36). 
Woody forms, tubes firmly fixed to cap. Polyporus (Pages 
37 and 38). 
(B) Fungus forming shelf. 
(a) Fungus fleshy. 
Tubes very shallow, Fungus waxy. Merulius (Page 41). 
Tubes long, Fungus large and juicy. Fistulina (Page 43, 
First Series). 
(J?) Fungus dry, woody. 
Tubes forming a definite layer all of same depth. Poly- 
porus (Pages 37 and 38). 
Tubes not forming a definite layer and of different depths, 
corky. Trametes (Page 40). 
(C) Fungus forming crust, with pores above. 
Pores small, deep. Poria (Page 39). 
Pores large, shallow. Merulius (Page 43). 
Many of the Spine Toadstools (Hydneae) have well marked 
spines on their lower surfaces on which the spores arc borne 
(Page 42). Some like Phlcbia. vaga (Page 43) form flattened 
plaques with crest-like wrinkles and veins. I'remellodon (Page 55) 
closely resembles a Hydnum but is gelatinous. 
The Stag’s Horn Fungi (Clavariae) contain the genera 
Sftarassis (Page 49) and Clavaria (Pages 50 and 51, First Series). 
parassis is a much branched sponge-like form without a stalk 
which grows to a large size. 
The Stinkhorns (Phalloideae) are a most peculiar group of 
Fungi (Pages 52 and 54. First Series). Mutinus is distinguished 
from Phallus by its smaller size and the absence of the helmet at 
the end of the spongy stem. 
The Puff-balls ( Lycoperdeae) are filled with powdery spores 
when ripe. 
(A) No pore formed. Thick outer layer which slowly decays. 
Scleroderma (Page 56, First Series). 
(B) Pore formed through which spores are distributed. 
Covering of one layer only. Lycoperdon (Pages 50 to 52). 
Covering of two layers, the outer of which turns back in 
the form of a star. Geaster (Page 57, First Series). 
Crucibulum is the sole representative of the Bird’s-nest Fungi 
(Nidularieae) here illustrated (Page 58, First Series).
