CLASSIFICATION 507 



T. rufum. — Ascophore subglobose or irregular in form, minutely 

 warted, cracked, rusty brown, 1-2J in. diam. ; gleba reddish brown 

 when mature, dissepiments whitish, then livid, mixed with tawny 

 lines ; asci broadly ovate, 1-4-spored ; spores broadly elliptical or 

 nearly globose, brown, densely covered with short, slender spines, 

 25-36x17-24/^. 



Wall of ascophore thick and somewhat cartilaginous, colour 

 variable, but always with a rusty tinge. Smell variable, sometimes 

 nauseous. Sometimes there is onl}^ one spore in an ascus, which is 

 then very large. 



In woods. Underground or partly exposed. 



T. scleroneuron. — Subglobose and somewhat lobed, as a rule 

 minutely warted or almost smooth, cracked, reddish brown, 1-2 in. 

 diam. ; gleba greyish at the centre, changing into reddish brown 

 towards the wall ; asci broadly ovate or clavate, 2-4, usually 

 3-spored ; spores subglobose or broadly elhptical, densely covered 

 with slender spines, 4-6 jj. long, 17-23 X 25 (j-. 



Distinguished from T. rufum by the deep red-brown colour of the 

 wall of the ascophore, by the broadly elliptical spores, and faint 

 aromatic smell. When dry the fungus becomes as hard as 

 wood. 



Underground. Rare. 



T. nitidum. — Ascophore globose or somewhat depressed, hard, 

 smooth, shining, with a tinge of reddish yellow, |--ij in. diam. ; 

 gleba white, then reddish brown, hard, the white dissepiments 

 springing from a pale point at the base ; asci 2-4-spored ; spores 

 broadly elliptical or subglobose, yellowish brown, densely covered 

 with rather long, slender spines, 20-30 x 15-24 /x, or 20-25 ft diam. 



Distinguished by the even, polished wall of the ascophore and 

 the small spinulose spores. 



Underground under trees. 



T. ferriigineum. — Ascophore irregular in shape, very soft, rusty 

 brown, minutely warted, often more or less cracked, 1-3 in. diam. ; 

 gleba soft, dry, granular, pale rusty brown with a few branched, 

 whitish dissepiments ; asci numerous, 2-4-spored ; spores ' from 

 elliptical to globose, brown, with a dense covering of slender spines, 

 18-25 X 15-18 i>-. 



Distinguished l:)y the very soft ascophore. Hard wlien dry. 

 Smell rather strong. 



Underground. 



Chceromyces 

 Ascophore without any opening to the outside, e^'en, ^\■ith a 

 distinct basal portion, wall often cracked ; gleba traversed by 

 numerous thin, branched lines ; asci oblong-ovate, 8-spored ; spores 

 globose, warted.
