Meliolinopsis Stevens n. gen. 



Perisporiaceous, like Meliolina except that the spores are 1-septate. 

 35. Weliolinopsis palmicola Stevens n. sp. 

 [Figures. 66, 67.] 



Mycelium amphigenous, superficial, aggregated in dense clumps around 

 the perithecia and spreading in a loose network over the surrounding leaf 

 surface; black in mass; single strands pale yellow by transmitted light, 

 slightly crooked, non-hypophodiate. Perithecia in groups in the centers 

 of the colonies, smooth, globose, non-ostiolate, about 275/1 in diameter. 

 Setae simple, black, crooked, almost uncinate, obtuse, very numerous 

 around the perithecium, thicker and darker than the mycelium, 200 to 

 300m long, 4yu thick. Asci not evanescent, usually 4-spored, surrounded 

 by very numerous gelatinous, hyaline, filiform paraphyses which are 

 crooked and longer than the asci. Spores dark brown, 2-celled, obtuse, 

 strongly constricted, surrounded by a thin hyaline, gelatinous sheath, 

 40 to 65 s 20 to 25ai. 



On Bactris sp. 



Trinidad: Cumuto, August 16, 1922, 1000. 



This species agrees with Meliolina except for its 1-septate spores and 

 for the very numerous gelatinous paraphyses. The spores in shape strongly 

 resemble those of Meliolina guaianensis and these two forms together 

 constitute interesting links connecting this one-septate Meliolinopsis with 

 the genus Meliola. 



Hyalomeliolina Stevens n. gen. 



Persporiaceous, perithecial setae long, simple, mycelium-like; asci 

 persistent; spores 3 to 5-septate, brown, end cells pale to hyaline.
