 224 ANNALS OF THE MISSOURI BOTANICAL GARDEN 



fuscous, simple and tapering upward or soon branching and 

 terminating in paler either subulate tips or somewhat flattened 

 ends; spores fuscous, subglobose, echinulate, 8-10 x 8-9m- 



The resupinate membrane may be 3 cm. in diameter; ascending 

 portion of fructification 2-3 cm. high, l|-2 mm. thick. 



On decaying leaves and sticks on the ground. Cuba. 



Berkeley & Curtis based their description of Thelephora den- 

 tosa on two collections made in Cuba by C. Wright in different 

 years; these collections are different specifically. The original 

 description applies chiefly to the earlier collection, made in 

 1857, which is unnumbered. I take my type of T. perplexa 

 from the later collection, C. Wright, 238. 



Specimens examined: 

 Exsiccati: Fungi Cubenses Wrightiani, C. Wright, 238, under 



the name Thelephora dentosa B. & C. 

 Cuba: C. Wright, 238, type (in Curtis Herb.). 



22. T. dentosa Berk. & Curtis emend Burt.^ 



T. dentosa B. & C. (Fungi Cubenses) Jour. Linn. Soc. Bot. 

 id: 329. 1867. 



Type: type and cotype in Kew Herb, and Curtis Herb, re- 

 spectively. 



Fructification coriaceous-soft, incrusting leaves and small 

 twigs on the ground and ascending as free, sessile, dilated, tri- 

 angular, flabelliform pilei which are dentate at the upper end 

 or deeply divided into a few finger-shaped divisions, honey- 

 yellow to tawny olivaceous throughout, minutely hairy under 

 a lens ; spores honey-yellow, globose to ovoid, weakly echinulate, 

 6-10 X 6-8 /x. 



Pileus 1 cm. high, 5 mm.-l cm. broad. 



On rotten vegetation. Cuba. June. 



As already stated in connection with T. perplexa, Berkeley 

 & Curtis cited for types of their T. dentosa specimens from two 

 collections made in Cuba by C. Wright. These collections were 

 made wdth an interval of several years between the collections, 

 which differ specifically. As noted by Berkeley & Curtis, their 

 description applies better to the earlier collection, to which I now
