 112 ANNALS OF THE MISSOURI BOTANICAL GARDEN 



S. fissum may yet be found as far north as the West Indies and 

 Central America. The species is noteworthy by its occurrence 

 on dead twigs in scattered, solitary, azonate fructifications which 

 are often deeply split into segments, and by absence of cystidia 

 and gloeocystidia. 



Specimens examined: 

 Exsiccati: Ule, Myc. Brasil., 42, under the name Stereum Huberi- 



anum. 

 Brazil : Panure, Spruce, 27, type (in Curtis Herb.) ; Amazonas, 

 Marmellos, and Jurnd, E. Ule, in Ule, Myc. Brasil., 42. 



23. S. cyphelloides Berk. & Curtis, Linn. Soc. Bot. Jour. 10: 

 331. 1868; Sacc. Syll. Fung. 6: 558. 1888; Massee, Linn. 

 Soc. Bot. Jour. 27: 172. 1890; Lloyd, Myc. Writ. 4. Stip. 

 Stereums, 35. 1913. Plate 3, fig. 20. 



Type: in Kew Herb, and Curtis Herb. 



Pileus small, flabelliform or spatulate, drying pinkish buff, 

 longitudinally fibrillose, bibulous, the margin entire, narrowed 

 behind into a short stem-like base; in structure up to 600 ii 

 thick, composed of thin-walled, hyaline hyphae 2|-3 11 in diam- 

 eter, interwoven in the subhymenium; hymenium even, dry- 

 ing of same color as upper surface of pileus; no conducting 

 organs, gloeocystidia, nor cystidia; spores hyaline, even, 4-5 X 

 3-3^ 11. 



Pileus 3-6 mm. wide, 5-7 mm. long. 



On a bank among moss. West Indies. February and March. 



S. cyphelloides differs from most Stereums in not having a hard 

 compact structure, as in S. rameale, for example; it is of soft and 

 bibulous texture but rather too thick for a Cyphella. The stem- 

 like base is flattened in the same plane with the pileus and has the 

 hymenium continued along its whole length, hence it is merely a 

 narrowed portion of the pileus. 



Specimens examined: 

 Cuba: C. Wright, 511, type (in Curtis Herb.).
