or spots, sometimes as much as 15 mm. in diameter, witli an elevated, 

 ratlier obscure, flexuous border. Spores cylindric-fusiform, rather acute 

 at each end, sparingly septate, hyaline, often flexuous, 20—30 x H p-.

Further observation shows that the origin of the conidia in this spe- 

 cies is subepidermal and that it is really a GyUndosporium, as that genus 

 is now understood. It was described as follows : 



Scattered over the lower surface of the leaf on small, rusty brown 

 spots, limited by the veinlets of the leaf and forming at length, by con- 

 < fluence, much larger (i— 1 cm.) patches with an irregular outline. The 

 leaf is also mottled above with rusty brown in wliich small, light colored 

 spots mark the position of the denser tufts beneath. Hyphse densely 

 tufted, nearly hyaline, short, (16 — 26 p-) lax, slightly swollen at the base, 

 bearing the cylindrical, nearly hyaline (with a slight yellowish tinge) 3— 

 -4 septate, granular and nucleate conidia, 70—100 x 5—6 /^-, more or less 

 curved and ends obtuse. Accompanied by an immature Sphoerella of 

 which it is probably the conidial stase.

A NEW GENUS OF PYRENOMYCETES. 



BY J. B. ELLIS AND B. M. EVEKHAET. 



Among the published species of Splmronema, we find two that are 

 ascigerous, and for their reception the following new genus is proposed. 



Hypsotheca, Ell. &> Everhart.— Perithecia (stroma?) subulate, sty- 

 losporiferous at base and with a medial or subapical enlargement above 

 containing the ascigerous nucleus. This latter character will distinguish 

 the proposed genus from Ceratostoma. Caliciopsis, Pk., is also closely 

 allied but is placed by its author among the Discomycetes.
