Fitzpatrick: Monograph of Coryneliaceae 221 



Type : Material labeled Hypsotheca calicioides E. & E. in the 

 herbarium of Ellis at the N. Y. Bot. Gard. (collected by Suks- 

 dorf in Washington, and sent to Ellis by Sprague). 



(Figures 35, 36, 47) 

 Mycelium in the cortical 'tissue of poplar, apparently sapro- 

 phytic; stromata 500-1 700 p. in diameter, more or less circular 

 to elongated, scattered or developing in rather definite lines, 

 which appear as concentric circles a few millimeters apart, ad- 

 jacent stromata occasionally confluent ; pycnidia and perithecia 

 borne frequently on the same stroma, cespitose ; perithecium 

 shiny to dull, when young glabrous, in age becoming definitely 

 roughened especially over the surface of the ascigerous swelling, 

 1400-1800/x long, coriaceous, becoming brittle in age or on dry- 

 ing, consisting of a stalk, a median or sub-median enlargement 

 containing the ascigerous cavity and a terminal beak ; the enlarge- 

 ment sub-cylindrical-vesiculose, 270-480^ long and measuring 

 in lateral diameter at the middle 200-340 fi, not observed to col- 

 lapse laterally as in the other species of the genus ; the stalk 

 100-170 fi in diameter, relatively shorter and more rigid than in 

 the other species, somewhat broadened at the base; beak at the 

 beginning merely a short conical continuation of the ascigerous 

 enlargement, 1 later more elongated, rigid and straight or some- 

 times curved, reaching in some cases 1 mm. in length, narrower 

 than the stalk, 75-125//, in diameter; the apex in the beginning 

 sharp-pointed and closed, sometimes possessing a minute umbil- 

 icus which resembles superficially an ostiolum, at maturity be- 

 coming fimbriate-lacerate, the hyphal elements spreading apart 

 and forming a broad, reddish-brown, fuzzy fringe around a 

 central funnel-shaped opening; asci ovate to clavate, 15-20 X 

 8—1 1 fx; spores sub-fusiform to ellipsoidal to oval, 6-10 X 3-5—5 

 (aver. 7X3-5/^); pycnidia 140^ in diam. ; pycnospores 2.5-3 l x 

 long, hyaline or in mass slightly yellowish. 



Ellis (10, 11) based his published descriptions of this species 

 chiefly on the material collected by Suksdorf in Washington on 

 poplar. He saw also, however, the material distributed by 

 Ravenel, 2 and regarded the two collections as identical. The 

 writer has examined material of both of these collections and 

 also of an additional collection in the herbarium of Ellis labeled 

 by him Hypsotheca calicioides (Fr.) var. caespitosa n. var. 



1 A double ascigerous enlargement forked at the upper end and bearing 

 two beaks was present in one case as an interesting abnormality.
