NOTICES OF NOKXH AMEUICAN FUNGI. 7 



No. 5189. On 3[agnolia tripetala, Pennsjlvania, Michener. No. 

 4078. 



431 (bis). Discosia grammita. B. Sf C. — Peritheciis liysteriifor- 

 mibus opacis, appenclicibus terminalibus. 



On dead Pceonia arhorea. New England. Rev. I. D. Russell. 

 No. 5873. 



Perithecia opaque hysteriiform ; spores triseptate, with an accu- 

 minate appendage at either extremity, '0008 long. 



* Discosia nitida. Lev. — On Magnolia. Car. Inf. No. 5023. 

 Spores '0008 long. 



This was distributed as D. ocellata, B. & C, but I consider it a 

 mere variety of Leveille's plant, which is far prettier. No. 2712 

 is a distinct variety, in which the cuticle remains opaque. The 

 spores in this specimen are triseptate. 



* Discosia faginea. Lib. — Alabama, Beaumont. No. 5100. 

 The spores are without septa, but they are clearly immature. 



432. Discosia xugulosa. — B. ^ C. — Peritheciis orbicularibus opacis 

 rugosis. 



On leaves of Carya. Alabama, Peters. No. 5210. 



This seems to be quite different from Z). artocreas, the perithecia 

 being rugulose and opaque, and not at all shining, as in that species. 

 No. 4696 from New Jersey, on Canja, is merely a diseased state of 

 the leaf. 



432 (bis). Discosia minima. B. tfc C, — Peritheciis minutissimis 

 innumeris punctiformibus, sporis utrinque appendiculatis. 



On leaves of Ilex. Alabama, Beaumont. No. 5113. 



Extremely minute, gregarious ; spores '0015 long, without septa, 

 but probably young, furnished as in D. grammita with a terminal 

 appendix at either end. There is a species almost as minute on 

 fruit of Dioscorea, Pennsylvania, Michener. No. 4149, but I 

 have not seen any fi'uit. 



* Melasmia acexina. Lev. — On leaves of 31yrsinites apparently. 

 Texas, Wright. No. 3772. 



1 do not see any difference between this and Leveillg's plant. It 

 has the same black patches seated on a yellow spot. Spores 

 minute, '00025 long. 



433. IM[elasm.ia ulmiicola. B. & C— Punctiformis prominula basi 

 epiderniide cincta e maculis rufis indefinitis oriunda. 



On leaves of Ulmus Americana, Massachusetts. No. 3391. 



Spots reddish-brown, indefinite ; perithecia dotlike, prominent, 

 surrounded at the base by the cuticle, spores minute, similar to 

 those of the last.. This is just intermediate between Melasmia and 

 Piggotia. 



433 (bis). Piggotia fraxini. B. Sf C. — Peritheciis hie illic in caes- 

 pites punctiformes congestis ; sporis oblongis miautis. 



On leaves of Ash. Pennsylvania, Michener. 1^0.5153. Hypo-
