 334 ANNALS OF THE MISSOURI BOTANICAL, GARDEN 



On bark. Base of John Crow Peak, altitude 5500 feet. 

 .Taniaica. April. 



The type of this species has so thick and spongy a hyme- 

 nial layer that I have tried to regard this specimen as the 

 fertile stage of S. Spongia, but the well-developed layer of 

 pillars is in the way of such reference and the hyphac are 

 rather coarser than in S. Spongia. 



Specimens examined : 

 Jamaica: John Crow Peak, L. M. Underwood, 2439. 



9. S. atratum Patouillard, Soc. Myc. Fr. Bui. 16:181. 1900. 

 Type: location unknown. 



Fructification resupinate, greatly extended, glabrous, shin- 

 ing, thin, with the margin fimbriate and incrusting; subicu- 

 lum black, formed of rigid, erect, short bundles composed of 

 hyphae but little branched, 4r-bfi in diameter, with the wall 

 thick and brown under the microscope; hymenial crust thin, 

 fragile, continuous, glabrous, ombre noir, paler at the per- 

 iphery; probasidia at first globose, 10-12/i. in diameter, 

 growing on the sides of erect hyphae of the hymenial crust 

 a little below their ends; spores and spore-bearing organs 

 not present. 



On living trunk of Eugenia Jamhos. Morne Gommier, near 

 Gallon, Guadeloupe. P. Buss. 



In comiection with the original description, Patouillard 

 stated that S. Spongia is ''epais, roux, spongieux, lacuneux," 

 and that 8. atratum is "tres mince, et noir." I have seen 

 no specimens of S. atratum and base the above account of 

 this species wholly on the original description. 



10. S. cirratum Burt, n. sp. 



Type: in Mo. Bot. Gard. Herb, and Humphrey Herb. 



Fructification resupinate, effused, coriaceous, spongy, dry, 

 cracked, velutinous, between Benzo-brown and brownish 

 drab, with fuscous subiculum, the margin divided into nar- 

 row, sinuous divisions; in structure up to 700/t thick, with 

 (1) next to the substratum a layer of interwoven hyphae, 

 which form (2) a layer of pillars not uniform in diameter, 

 composed of hyphae loosely interwoven, curled together.
