under the na'iies fnmarfo, Ant'nnaria. Capnodium, etc., but their positive 

 connection with these plants, positive at least in the case of the specimen 

 figured in Plate III, Fig 2, of course destroys any sort of specific individu- 

 ality. I cannot say that they are reproductive bodies, but they certainly 

 look like it. Other plants not distantly related have such forms of fruit. 

 It is probable that the conceptacle, v?ith its contained sporangia, in all these 

 plants, is the result of a peculiar union of specialized cells (17), as in the 

 Perono-porise. 



Sphperotheca caMagnei, Lev. On Taruxicum, Hop, Spirea, etc. To 

 this species we refer with doubt the plant figured on Plate III, Fig 3, 

 found on Ererhfites hleraxifoUus, but the conceptacle is larger (1-245 in.) 

 and the mycelium denser than in any undoubted plants of the species no- 

 ticed, and the appendages somewhat diiferent. Instead, too, of being dis- 

 tributed over the plant, this is found almost entirely upon the stems and 

 iiuder sides of the leaves, in patches. Appendages (of which there are one 

 to three ) colored to a septum. Sporangium one, spores eight, oval, 1-8000 

 by 1-4300 in. 



PhyVnctinia gtittata, Lev., (Plate IV, Pig. 6.) Common on Fraxinus 

 viridis. This species is reported to be common on Quercus, Carpinus, Ber- 

 beris, Alnus, (Jorylus, etc. 



Podo^plioera kunzei (?), Lev. {Plate III, Fig. 2.) On cultivated 

 cherry. This is almost surely not kunzei, Lev., but it is the nearest to it 

 of any I know and I am loth to call it new, since so conspicuous and mjurious 

 a species could hardly have escaped attention. Leaves of all varieties of 

 cultivated cherries were distorted and caused to fall, from the middle of 

 the summer until autumn. My notes are as follows : Mycelium thin, evanes- 

 cent: appendages about twelve, colored at base, sometimes septate, simple 

 or but little dichotomously forked; conceptacle black, 1-300 in., gregarious 

 on the upper side of leaves. Sporangium eight-spored. The spore-like forms 

 on the appendages have already been referred to. These were by no means 

 on all the plants, but occurred on this one as shown. 



Microapliseria, extensa, G. & P., (Plate IV, Fig. 2.) On Quercus rubra 

 and Q. palustris in woods. The upper sides of the leaves are conspicuously 

 whitened. 



M.friesii, Lev. Very common on Syringa vidgaris. The concepta- 

 cles are sometimes abundant, but not always. The divided and curled tips 

 of the appendages are very beautiful in perfect specimens. 



M. ravenelii. Berk., (Plate IV, Figs. 7 to '11.^ On Gleditchia tri- 

 aranthns. This is certainly the same as my specimen in RaveneVs exxiccati, 

 but the mycelium is much more dense. In this respect it surpasses all I 

 have seen. The leaves are very white. 



M. elevata, n. sp., (Plate II, Fig. 4.) Upper sides of leaves of Ca- 

 talpa, bigmonioides. Mycelium thin, web-like, rather evanescent. Concepta- 

 cles 1-250 in., conspicuously reticulated, raised from the leaf ; appendages 

 about twelve, colored at base, often simple, sometimes branched near the 

 base, usually 2 to 4 times dichotomously forked, very long ; sporangia four.
