X. conocephala, B. & C. Cuban Fungi, No. 781. 



Very large, cespitose from an obtusely conical base, umber color, 

 rimulose, here and there contracted in drying. Ostiola scattered, sub- 

 prominent. Stipe short, longitudinally sulcate. 



On rotten wood, Ohio (Morgan). 



The Ohio specc. were determined by Cooke, and from them we 

 add the following notes: Fertile heads 6-9 cm. long, about 1 cm. 

 thick, subcylindrical, dirty-brown outside, quite hard when dry and 

 lacunose-wrinkled, arising from a common, subtuberculiform base 

 4-5 x 2-3 cm. Perithecia sunk in the stroma, ovate, about 1 mm. 

 high by | mm. wide, necks short, terminating in the scattered, hemi- 

 spheric-prominent, rather large, black ostiola (about like those of 

 Nummularia Bidliardi). Asci cylindrical, p. sp. 80-85 /i long. 

 Sporidia uniseriate, navicular-fusoid, opake, 15-18 x 4J-5 p. 



X. castorea, Berk. Fl. Nov. Zel. p. 204, tab. 105, fig. 10. 



Stipe short, at first spongy-velutinous, then bare, rugose. Head 

 clavate, elliptical or ovate, obtusely rounded at the apex, much com- 

 pressed, minutely areolate and roughened by the more or less promi- 

 nent ostiola. Asci narrow. Sporidia ovoid-oblong, fuliginous, 10 [x 

 long. ) 



On rotten wood, Ohio (Morgan). 



The above diagnosis is from Saccardo's Sylloge. The Ohio specc. 

 (det. by Cke.) are cespitose, arising from a common spongy-velutinous, 

 irregular-shaped base 1-2 cm. high, stipes less than 1 cm. long; heads 

 1J-3 cm. long, |-1 cm. wide, flattened, brown. Perithecia ovate- 

 globose, about | mm. high, monostichous, buried. Ostiola papilliform 

 or subhemispherical, prominent in the mature specc. Asci (p. sp.) 

 50-60 x 5 //, with a slender stipe about one-half as long. Sporidia 

 uniseriate, elliptical, slightly inequilateral, 7-8x4-5 /i. The surface 

 of the clubs, especially in the immature, dry specc, is cracked into 

 minute areolae. Resembles X. corniformis, Fr., only broader and 

 compressed. 



X. Titan, B. & C. Grev. IV, p. 47. 



"Five inches long, 2 inches wide, sausage-shaped, convex on one 

 side, hollow on the other, hard, solid, dirty-white, stained with the 

 sporidia and dotted with the prominent ostiola." 



(On wood)? Texas (Lindheimer). 



X. fulvella, B. & C. Cuban Fungi, No. 788. 



Clavate, rubiginose, papillate. Perithecia subprominent. Ostiola
