Spegazzini's Brazilian specimens. On decaying tree trunk, 

 Castillo Viejo. (C. L. S.) 



Xylaria olobapha Berk. 

 Growing on small, fallen, dead trees, Castillo Viejo. ( C. L. S. ) 



X. TITAN B. & C. 



On dead tree, Ometepe. (B. S. & C. L. S.) Some imma- 

 ture specimens which I collected at Castillo Viejo were thought 

 to belong to this species. 



X. OBOVATA Berk. Cuban Fungi, No. 785. 



Gregarious, sessile or with a short, thick, smooth stipe 2-10 

 mm. long, globose or ovate, smooth, 10-13X13-20 mm., about 

 the color of dark, weather-beaten wood, covered with a thin, 

 separable crust, texture of the inside of the stroma spongy- 

 fibrous, pale rose-color. Perilhecia peripherical, buried in the 

 stroma just under the crust, monoslichous, ovate, about %-i 

 mm.; ostiola punctiform, minute. Asci (p. sp.) cylindrical, 

 100-110x6//, with a slender stipe, paraphysate, 8-spored. 

 Sporidia uniseriate, oblong-navicular, obtuse, opake, 20-23 x 



5-6 /^. 



The stroma finally becomes more or less hollow by the 

 shrinking and decay of the inner substance and the perithecia 

 then adhere to the inner surface of the thin, enclosing crust. 

 The Nicaragua specimens agree perfectly with Wright's 

 Cuban specimens. 



On the bark of a live tree near the ground, Castillo Viejo. 

 (C. L. S.) 



X. SCHWEINITZII B. d' C. 



Capitulum elliptical, obtuse, cork}', compact, sparsely rimose, 

 with an elongate, discrete, very smooth, varnished stipe. 

 Perithecia globose; ostiola scattered and scarcely prominent. 

 Sporidia cymbiform, 30 // long. 



On decaying wood, Surinam and Ceylon. The Ceylon 

 specimens had shorter stipes than the Surinam specimens. A
