NEW SPECIES OF TROPICAL FUNGI. y t 



ii. Kretzschmeria spinifera EU. <£■ Macb. 



Stromata oblong-ovate, 3-6 mm. in diam., and 4-6 mm. 

 high, superficial, crowded and subangular from mutual pres- 

 sure but not confluent, rough, black, carboraceous, rounded 

 above, bearing considerable resemblance to the stromata of 

 JJypoxylon cokarens. 



Perithecia 1-3 in a stroma, large (i/^ mm.), globose; 

 ostiola at first strongly papillose, soon prolonged to short-c\ 1- 

 indrical; asci not seen; sporidia broad, navicular-fusoid. con- 

 tinuous, opaque, compressed, 25-35x10-12 « and 6-8" thick; 

 viewed edgewise mostlv narrowed in the middle. 



Resembles K. ccenopus Mont., but differs in its prolonged 

 ostiola and larger sporidia. The stromata also are sessile and 

 connected at base bv a slight stromatic crust. 



On decaying bark. Mexico. ( C. L. Smith.) 



12. DlATRYPE TRIFIDA EU. & Macb. 



Stroma placoid, 2^-3 cm. across and 2^2-3 mm. thick, of 

 tough, hard, carbonaceous texture, not projecting much above 

 the surface of the wood, bearing the oblong-ovate IXJ2 mm. 

 perithecia closely packed in a single superficial layer and cov- 

 ered by a thin, black, carbonaceous sheet, pierced and rough- 

 ened by the projecting, short, conic-cylindrical, rough ostiola. 

 The perithecia rest on a dirty yellowish, grumous layer about 

 x / 2 mm. thick and subtended by a thin. hard, black, carbonaceous 

 layer joined at the edges to the superficial sheet and prolonged 

 below, in the central part, into a short, hollow stem (elliptical 

 in outline on a cross section), and 2-3 mm. long, the cavity 

 filled with a substance of the rotten wood into which it pene- 

 trates. Asci (p. sp.) 15-20x3-3^,", with a filiform stipe. 

 Sporidia partlv biseriate allantoid, hyaline (with a yellowish 

 tinge), 3xi". Has the outward characters of Hypoxylun. 



On rotten wood. Tehuantepec, Mexico. (C. L. Smith.) 



13. Hypoxylon fibuliforme E.SsE. 



Stroma lenticular or button-shaped 2-5 mm. in diam.. black, 

 sessile, roughened by the papilliform ostiola. Perithecia
