 108 ANNALS OF THE MISSOURI BOTANICAL GARDEN 



fan-shaped fructifications in clusters on dead wood, pale cinna- 

 mon color when dry, presence of gloeocystidia, and small sub- 

 globose spores constitute a group of characters by which dried 

 specimens of S. decolorans may be distinguished from other 

 species in our region. 



Specimens examined: 

 Jamaica: W. A. Murrill, 1181 (in N. Y. Bot. Gard. Herb.). 

 Cuba: C. Wright 234, 248, type (in Kew Herb, and Curtis 



Herb.); Santiago de las Vegas, Van Herman, comm. by 



F. S. Earle, 257. 

 Trinidad: Carengo, M. A. Carriker, comm. by W. G. Farlow, 1.

 329. 1868; Sacc. Syll. Fung. 6: 525. 1888. Podoscypha radi- 

 cans (Berk. & Curtis) Patouillard in Duss, Fl. Crypt. Antilles 

 Fr. 230. 1904. 



Type: in Kew Herb, probably. 



"Plant If inch high, f of an inch broad, spathulate or subin- 

 fundibuliform, split on one side and slightly lobed, minutely 

 striate, with raised lines, tawny, coriaceous. Stem f of an inch 

 high, If line thick, incrassated at the base, and sending off 

 strong branched roots. Hymenium nearly even, fuliginous; 

 spores apparently fuliginous." 



The above is the original description of the type specimens, 

 collected in Surinam, Guiana, by Hostmann, 489. My knowl- 

 edge of the species is based upon a later collection made in Cuba 

 by C. Wright and determined by Berkeley. This specimen 

 and the others cited below show well the longitudinal raised 

 lines on the upper surface of the pileus, which is thicker than in 

 related species, being 1-1 1 mm. thick, and the hymenium 100- 

 200 m thick; some specimens have dried with the upper surface 

 pinkish buff and others from wood-brown to Verona-brown; 

 hymenium even, wood-brown to fuscous; stem 10-15 mm. long, 

 3-4 mm. in diameter, sometimes radicated to reach buried wood; 

 no cystidia nor gloeocystidia; spores hyaline, even, becoming 

 minutely rough-walled and sometimes slightly angular, 6 X 5 ju.
