342 The North American Cup-Fungi 



Only one specimen of this species has been seen from North 

 America. While the spores and asci are slightly smaller than 

 indicated in European descriptions, the specimens appear to be 

 otherwise identical. While placed in the genus Pezicula by 

 Saccardo, the conidial stage has not been observed. Since the 

 name given this species is untenable we dedicate the species to 

 Dr. Brenckle who collected the only specimen seen from America.

 (Plate 141, Fig. 2.) 



The conidial stage (Sphaeronema) accompanies the apothecial 

 both springing from a floccose stroma ; pycnidia large and spike- 

 like, black but covered with white flakes, reaching a length of 

 1.5 mm., swollen below; macroconidia 10 X 20-24 ju and borne 

 on sporophores equalling or exceeding the length of the spore. 



Apothecia cespitose in rounded or elongated clusters, or 

 rarely occurring singly, reaching a diameter of 1 mm., pale- 

 yellowish, sessile, or tapering into a short, stem-like base; 

 hymenium slightly concave, or plane, not darker than the outside 

 of the apothecium; asci broad-clavate, reaching a length of 120 ^ 

 and a diameter of 16-18 /x, 8-spored; spores irregularly 2-seriate, 

 ellipsoid and often slightly curved, 8 X 24-27 n, becoming 

 1-3-septate; paraphyses slender, slightly enlarged above, the 

 ends free, branched, hyaline, about 2 /z in diameter. 



On Acer (spicatum?). 



Type locality: Near Ithaca, New York. 



Distribution: Known only from the type locality.

So far as the ascigerous stage of this species is concerned it 

 can scarcely be distinguished from Pezicula acericola. However, 

 the two are apparently entirely distinct in their conidial stages.
