THE NORTH AMERICAN SPECIES OF GL.OEO 



SFORIUM 



BY J. B. ELLIS AND BENJAMIN M. EVERHAKT. 



In this genus which belongs in the Melanconieoe, the spores borne 

 on basidia usually bacillary or acicular and fasciculate, originate in 

 masses (acervuli) beneath the epidermis through which they finally burst 

 in the form of a tendril or globule. The spores, mostly ovate-oblong, 

 are hyaline or nearly so, and are not enclosed in any distinct perithecium. 

 Saccardoin Syll., vol. Ill, restricts Glmosporium to those species having 

 continuous spores, placing those with uniseptate spores in Marsonia, and 

 those having spores with two or more septa in Septogloeum but we will 

 here include all under Gloeosporium. 



A. Spores continuous. 



1. Glceosporitjm Hamamelidis, Cke., Grev. XII, p. 26. 

 Amphigenous. Spots 1 cm. broad, suborbicular, dark brown.

Acervuli minute, scattered, epiphyllous, the thick tendrils pinkish when 

 dry. Spores oblong or cylindrical, colorless, obtuse at each end, straight 

 or slightly curved, 15 — 25 x 6i — 7i P--, generally 4-nucleate.
