-p2 NATURAL HISTOKY BULLETIN 



oblong or elliptical, longitudinally striated, black, lips slightly 

 opening, about 1 mm. long and half as broad; asci clavate, 8- 

 spored; spores partially 2-seriate, straight or slightly curved. 

 3-septate, scarcely constricted, 20 to 25 by 8/x. 



On bark of wild cherry (Primus sp.) 



The spores of this genus are similar to those of the genus 

 Hysteropatella but the plants differ in that the lips do not ex- 

 pand as in that genus or, if at all, only slightly. 



GLONIUM Muehl ; Schw. Schr. Nat. Ges. Leipzig 1 : 50. 1822. 



Plants erumpent, linear, elongated, sometimes radiately ar- 

 ranged, carbonaceous or tough-membranaceous, opening by a 

 longitudinal cleft; asci cylindrical to clavate, 8-spored; spores 

 1-septate, hyaline. 



Distinguished by the hyaline, 1-septate spores. Two species 

 common. 



KEY TO THE SPECIES. 



Plants radiately arranged G. stellatum. 



Plants lying parallel with each other G. parvulum. 



Glonium stellatum Schw., Schr. Nat. Ges. Leipzig 1: 50. 

 1822. 



Subiculum effused, brownish-black, often covering consider- 

 able area (2 or more cm.) composed of slender, branching, inter- 

 woven hyphce; apothecia seated on the subiculum, radiately ar- 

 ranged forming patches 2 to 4 cm. in diameter, entirely cover- 

 ing the subiculum, opening by narrow clefts ; asci cylindrical, 8- 

 spored; spores more or less crowded, fusoid. hyaline, 1-septate 

 and constricted at the septum. 20 to 22 by 5 to 6/x. 



On rotten wood of various kinds. 



A species very distinct from any of the other forms here do- 

 scribed in the presence of the black subiculum and the stellately 

 arranged apothecia. The species was wound in great quantity 

 at Mt. Pleasant on decaying logs of butternut. It has also been 

 observed in North Dakota and probably has a wide distribution.
