175 tJ..), conic-hemispheric, base slightly sunk in the bark, ostiolum 

 papilliform. Asci oblong 75-80 x 12 ji. sometimes shorter and broad- 

 er (45-50 X 15 //.). Sporidia biseriate, ovate oblong, pale brown, 3- 

 septate, finally 6-septate and slightly constricted across the middle, 

 lower end subacute, about 20 x 8-9 ,a. Teichospora pruniformis 

 (Nyl.) which is also found on bark of poplar and willow is much 

 larger (J mm. diam.). 

 Nectria diplocarpa. 



On thallus of some foliaceous lichen (Parmelia)'! on trunk of a 

 tree, Farmington, N. Y., Dec, 1888, Edgar Brown, No. 17. Peri- 

 thecia gregarious or subcespitose (2-3-connate) superficial, ovate, 

 about i mm. diam. clothed with white septate, sparingly branched, 

 substrigose hairs, collapsing more or less distinctly above, deep flesh 

 color, ostiolum papilliform, large and distinct, smooth. Asci clavate, 

 40-50 X 8-12 //. filled with reddish granular matter at first, then con- 

 taining 4 oblong elliptical, hyaline spoi-es, 8-12 x 4-5 //., 1-septate 

 and more or less constricted at the septum, ends rounded and obtuse, 

 lying irregularly in the asci. Paraphyses apparently present but 

 very obscure as are also the asci which are soon dissolved. Together 

 with the sporidia already described are .others much larger, 30-45 x 

 18-25 /J: granular, hyaline, 1-septate and strongly constricted at 

 the septum, oblong-elliptical in shape with the ends obtuse and 

 rounded. It is not easy to see just how these large spores originate 

 but there is good reason to believe them true ascospores as in several 

 instances asci were seen containing, in addition to the smaller 

 sporidia, a single sporidium intermediate in size between the smaller 

 and the larger ones. Only one of the larger intermediate sized 

 spores was seen in the same ascus and as far as we could judge only 

 one of these large sized spores was produced in an ascus, though 

 when the spore had reached the largest size mentioned the asc\is 

 which containe(i it had disappeared. If this is the correct view the 

 large spores are normal and mature and the smaller ones undeveloped 

 and immature. In examining our Exsiccati we find that specimens 

 collected in Missouri by Demetrio on thallus of P(m?ie/i'a and issued 

 by Dr. Winter in his Rabenhorst-Winter Fungi, No. 3252, as 

 Nedria lecanodes Rabh. are the sa,me as this. The description, how- 

 ever, of N. lecanodes does not apply to this, that species having 

 sporidia only 9-11 x 3-4 .a. and in fact the specimen of N. lecanodes 

 in DeThumen's Mycotheca, 1746 and Fungi Gallici, 665 (both 

 collected by Madame Libert) as well as those in Rehm's Ascomy-
