restrict their species. This earlier collection was distributed 

 by C. Wright, unnumbered, under the name Thelephora dentosa 



B. & C. before the publication of the description of this species, 

 and the cotype in Curtis Herb, is unnumbered also. By what 

 was apparently a slip of the pen, Berkeley cited this type as 



C. Wright, 507. By the kindness of Dr. Farlow I have been 

 permitted to examine the manuscript records which show that 

 Wright collected only one No. 507, which was determined by 

 Berkeley as Xylaria ohovata Berk, and is cited under this species 

 by Berk. & Curtis, Jour. Linn. Soc. Bot. lo: 380. 1867. I 

 find in Curtis Herb, such a specimen labelled Xylaria ohovata 

 Berk., Cuba, C. Wright, 507. I conclude that the type and 

 cotype of T. dentosa B. & C, first cited in their description, 

 are from the collection distributed by C. Wright, unnumbered, 

 under the name Thelephora dentosa B. & C. 



Specimens examined: 

 Exsiccati: Plantae Cubenses Wrightianae, unnumbered, under 



the name Thelephora dentosa B. & C. 

 Cuba: C. Wright, cotype (in Curtis Herb.).

Type : an authentic specimen from Fries, in Kew Herb. 



Fructifications cespitose, from byssoid becoming fleshy, vari- 

 able by incrusting habit, pale buff at first, main portions 

 becoming purplish-fuscous (Rood's brown) with age, ramose- 

 spiculous, tips penicillate and whitish; spores umbrinous under 

 the microscope, irregular, echinulate, 8-9 x 6-7 /x- 



Clusters 1-2 cm. high, 2-4 cm. in diameter, single fructifica- 

 tion 1-2 cm. high, about 1 mm. in diameter, with branches 

 spreading 4-6 mm. 



On leaves on ground in moist groves. Ohio to Wisconsin. 

 ^ July. Rare. 



The best specimens which I have seen have main trunks of 

 the fructifications running side by side over partially decayed 

 beech leaves and confluent into an effused mass. These trunks 

 ascend obliquely from the leaves to a height of 1-2 cm., branch 

 sparingly, and terminate in spiculous tips. The fructification
