 334 ANNALS OF THE MISSOUBI BOTANICAL GAKDEN 



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

 Jamaica. 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 hyphae are 

 rather coarser than in S. Spongia. 



Specimens examined: 

 Jamaica: John Crow Peak, L. M. Underivood, 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, 4-5/^ 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/a 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. Duss. 



In connection with the original description, Patouillard 

 stated that S, Spongia is ^^epais, roux, spongieux, lacuneux,'^ 

 and that 8. atratum is ^Hres mince, et noir.'* I have seen 

 no specimens of 8, 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/* 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.
