38. Stereum reniforme, Fr. Ep. p. 546. "Helvetia nova." 

 Herb. Mus. Brit. 



Herb. Mus. Brit. Without habitat. Probably from Swartz. 



Stem more than an inch high, about one line thick, lateral, 

 attenuated upwards, downy, ferruginous, sprinkled, as is the 

 whole plant, with short bright brown setae. Pileus 1 inch 

 broad, about ^ an inch long, thin and flexible, but coriaceous, 

 reniform, slightly lobed, obscurely zoned, marked with very 

 fine radiating raised lines of a golden cinnamon-brown. Edge 

 very thin and acute, slightly waved. Hymenium even, of the 

 same colour as the pileus, setulose. 



I have referred this beautiful plant to S. reniforme, Fr., with 

 which it very closely agrees, differing chiefly, as far as may 

 be judged from the short diagnosis, in its more golden hue. 

 The colour and substance are exactly those of some of the 

 bright-coloured exotic forms of Stereum rubiyinosum.

39. Stereum atratum, Fr. Umbonato-sessile, pileo tenui 

 rigido laevi fusco nigro-fasciato subtiliter olivaceo-velutino de- 

 mum glabro versus marginem undulatum pallidiori ; hymenio 

 demum rimoso glabro atro. Helvetia atrata, Swartz ! Prod, 

 p. 149. Thelephora atrata, Fl. Ind. Occ. p. 1933. 



Jamaica, Swartz. Herb. Mus. Brit. 



Pilei 14 inch long, 1 inch broad, laterally connate, rotun- 

 dato-cuneiform, slightly lobed or undulated, thin but very rigid, 

 clothed at first with minute subolivaceous velvety down, dark 

 brown, with narrow black concentric bands ; substance cer- 

 vino-ferruginous. Hymenium dark brown, rather scabrous 

 but not bristly, concentrically cracked. 



The specimen which I have had an opportunity of inspect- 

 ing is old and in a bad state, but it presents one or two cha- 

 racters not noticed by Fries.

40. Stereum versicolor, Fr. Umbonato-sessile submembra- 

 naceum ; pileo subtiliter villoso ; villis radiantibus ; zonis mar- 

 gineque glabrescentibus fuscis variegato ; hymenio laevi gla- 

 bro pallido. Helvetia versicolor, Swartz ! Prod. p. 149. The-

Jamaica, Swartz ! Herb. Mus. Brit. 



Pilei 1 inch long, laterally connate, umbonato-sessile, of a

 radiating direction. Hymenium pale ochre, very smooth.
