tichous, oval, one-celled, at first hyaline, finally opaque and 

 black, surrounded by a more or less distinct hyaline coating 

 about 25-28x18-20,", expelled and blackening the matrix when 

 mature. 



If this interesting fungus is to be placed in Melanospora^ it 

 must be in the subgenus Vittadinula as recognized by I^indau 

 in Engler & Prantl Pflanzenfam. 1: Part i, 353. Its position 

 here is at best somewhat anomalous, and a revision of this inter- 

 esting but poorly understood group would probably show that 

 it should be considered as constituting a new genus. Its final 

 retention in the Hypocreales is perhaps a matter of doubt. It 

 closely approaches the Sordariaceae, and serves as another in- 

 stance of the relationship between this family of the Sphaeriales 

 and the Melanosporeae. 



Abundant on bark of fallen log in wet woods east of San- 

 turce, altitude 10 feet. January. No. 4341. 



SPHAERIALES. 



Enclothia longirostris sp. nov. 



Stomata thickly scattered over large areas, sometimes con- 

 fluent, bright yellow, deeply seated in the matrix, becoming 

 erumpent, usually somewhat elongate, about 2-3X5-6mm.: peri- 

 thecia 5 or 6 to 1 5 or more in each stroma, deeply buried, black, 

 about ^mm. in diameter, ostioles long exserted, reaching nearly 

 I cm., brownish-yellow, roughened by the adhering stromatic 

 material: conidia very minute, about 2x1^, producing coral red 

 tendrils from some of the ostioles: asci spindle-shaped, delicate, 

 thin walled, a paraphysate, about 25-30x6/": ascospores 8, hya- 

 line, oval, at length about equally uniseptate, about 6x3^. 



This is a ver}^ conspicuous species from the bright yellow 

 stromata and long brownish-yellow ostioles. It is said to be 

 orange yellow when fresh. 



On bark of fallen log in wet woods, calcareous hills east of 

 Santurce, altitude 10 feet. January. No. 4340.
