 535. 1888. T. dissecta Leveilte, Ann.' Sci. Nat. Bot. III. 5:

Illustrations: Lloyd, loc. cit. 



Type: authentic specimen from Montagne in Kew Herb. 



Pilei solitary or cespitose, sessile or barely stipitate, coriaceous, 

 thin, white, wedge-shaped, deeply cleft into narrow segments 

 which are more or less pectinate along their margins and apex 

 and have these teeth-like portions incurved; no cystidia; no 

 gloeocystidia; spores hyaline, even, subglobose, 4-5X3^-4 m. 



Pileus 7-50 mm. long, 5-40 mm. broad. 



On decaying wood and bark and dead herbaceous stems. 

 Carolina to Bolivia. July to September in West Indies and 

 February in Bolivia. 



The pilei of S. Hartmanni occur in small tufts of two or three 

 in the specimens which have been seen; they are very dainty 

 and unique by the narrow pectinate margins and tips which are 

 more or less incurved; rarely these teeth occur on the lower 

 surface of segments of the pileus in a manner suggestive of teeth 

 of an Irpex but they are in most cases marginal. The maximum 

 dimensions of the pileus are from the Porto Rican collection; 

 the other specimens do not have pilei more than 2-3 cm. long. 

 I have not seen the type of Thelephora dissecta LeV., which was 

 collected in Guadeloupe; the description agrees so well with S. 

 Hartmanni that I have followed Lloyd's conclusion that T. 

 dissecta is a synonym of S. Hartmanni.
