1890.] NATURAL SCIENCKH OF I'lIILADELPHIA. 247 



Tuhercularia has allantoid hyaline coiiidia 6-8 x li-2 //. on basidia 

 35-40 /'.. long, branched above. This is according to the specimens 

 in DeThumen's Mycothcca and in Fungi Gallici the T. samhici 

 Cda. We are not aware that its ascigerons state has ever been ob- 

 served before. 



Nectria athroa. 



On decaying sycamore log, Manhattan, Kansas, Feb., 1889. 

 Kellerman and Swingle, No. 1325. Densely gregarions. Peri- 

 thecia ovate, 150-200 X 110-120 //. dark red, smooth or nearly so, 

 not collapsing. Asci (p. sp.) about 35 //. long cylindrical, evanes- 

 cent. Sporidia uniseriate, oblong-elliptical, hyaline, obtuse at the 

 ends 1-septate and slightly constricted, 5-6 x 2^> //.. This has the 

 general appearance of N. ditissima, Tul. but besides the more 

 regularly shaped perithecia the sporidia are mnch smaller. The asci 

 are with difficulty seen so that this might be taken for a stylosporous 

 fungus only from the fact that here and there series of eight spores 

 lying end to end indicate the presence of asci. 



Nectria mammoidea, Phill. & Plow. 



This species was found at Newfield some years ago on outer bark 

 of living apple trees and again Dec, 1888 on outer bark of living 

 Quince trees. The Newfield specimens agree with authentic speci- 

 mens from Plowright in all respects only the sporidia are a 

 little smaller (15 x 5-6 //.). In Plowright's specimens they are 18- 

 22 X 6-7 /': and subinequalateral. The Newfield specimens were 

 immature, the asci being mostly filled with granular matter. 



Neotria pithoides. 



On dead alders, British Columbia, May, 1889. Macoun, 122. 

 Densely cespitose forming suborbicular tufts, l2-2j mm. diam. 

 Perithecia ovate, dark red, about | mm. diam. muriculate-roughened, 

 colla])siug above so as to appear truncate, but only slightly concave, 

 appearing in profile like small jars. Ostiolum papilliform only 

 slightly prominent. Asci cylindrical, 75-80 x 5 /j.. Paraphyses 

 not seen. Sporidia 1-seriate, oblong-elliptical 2-nucleate, becoming 

 1-septate 6-10 x 3-3=] />., smoky hyaline. The perithecia . are 

 seated on a convex yellow stroma 50-100 together and when young 

 are clothed with a few short white glandular hairs. Nearly allied to 

 N. microspora, C. & E. which has less numerous paler red, smoother, 

 more irregularly collapsed perithecia. The specific name from Grk. 

 pithos a barrel.
