130 FUNGUS-FLORA. 



when fresh ; sometimes with a distinct round stem i in. or 

 more in height, at others several plants grow close together, 

 having their stems more or less confluent at the base. It has 

 no relationship with Cladoderris, as suggested by Fries in 

 .Summa. Veg. Scand., p. 332. 



Stereum tuberosum. Mass. 



White, becoming pallid or reddish, pileus cut nearly or 

 quite down to the tuberous base into narrow irregular seg- 

 ments arranged in an infundibuliform manner ; stem when 

 distinct, slender ; hymenium almost even ; spores elliptical, 

 colourless, smooth, 78 x 5 /x. 



Thelephora tuberosa, Fr., Grev., Sc. Or. FL, t. 178 ; Berk., 

 Outl., p. 267 ; Cke., Hdbk., n. 892 ; Stev., B. Fung. ii. 262. 



On the ground. About 1 in. high. Pileus infundibuliform 

 but cut into narrow segments, removed from Tlielephora on 

 account of the smooth hymenium and elliptical smooth, 

 colourless spores. Distinguished from. S. Soicerbei by the 

 pileus being cut down nearly to the base into narrow 

 .segments, and the tuberous base to the stem. 



Stereum undulatum. Mass. 



Pileus whitish becoming tan, depressed, minutely fibrillose, 

 margin undulated, stem short, villous ; hymenium minutely 

 Telvety, pale tan ; spores broadly pip-shaped, 10 x 6 /A. 



Thelephora undulata, Fr., Hym. Eur., 663 ; Stev., B. Fung. 

 262. 



On the ground, From ^-1 in. high, pileus depressed or 

 funnel-shaped, stem short, remarkable for the minutely 

 -velvety, buff hymenium. 



Stereum multizonatum. B. & Br. 



Tough and cartilaginous when fresh, pileus deeply infun- 

 dibuliform, variously cut and lobed and passing into a short 

 stem, bright brownish flesh-colour, zoned with darker bands ; 

 hymenium smooth, paler than the pileus, rugulose, powdered 

 with the white spores ; numerous pilei are variously grown 

 together, the stems are also confluent at the base, thus 

 forming dense tufts ; spores elliptical, colourless, 8-9 x 

 4-5 p..
