Living leaves of Sophoni scricen, Pursh. 



Mr. Braudegee remarks concerning tiiis fungus that it is very omiuou at Canon 

 City, about one-half the Sophora i)lants being affected by it. The plants attacked by it 

 become more ei'eet in habit and do not blossom. The sori sometimes occur sparingly 

 on the upper surface of tlie leaf also. The specific name is suggested by the hyaline 

 membrane that at first covers them. 



PucciNiA NiGUESCENS, 7'/: — Spots none; sori rather prominent, cauline, oblong, 

 blackish-brown or black; spores smooth, elliptical or oblong, obtuse or Ijluntly pointed, 

 slightly constricted at the septum, .OOb'3-.0018 inch long, .0008-.001 broad; j)edicel col- 

 orless, two to four times as long as the spore. 



Stems and branches of Sdloin Idureoldtn, Willd. 



No leaves of the host plant accon)panied the specimens sent, so that I am not able 

 to say whether the fungus ever attacks the leaves or not. 



The two following species have been received from the sources given at the end of 

 the descriptions: 



DiATRYPELLA F]{OSTii. Pk. — Stroma verrucjefoi-m, rather i)rominent, convex or 

 hemispherical, scarcely one line broad, sometimes ccnifiuent, partly covered by the 

 closely adhering fragments of tlu^ rujjtured epidermis, black externally, greenish within, 

 forming a white spot on the wood beneath ; peritlieeia sub-globose, generally ten to fif- 

 teen ; ostiola obscure; asci sub-cylindrical, scarcely pedicellate, polysporous; spores yel- 

 lowish in the mass, cylindrical, curved, .00025-. 000;J5 inch long. 



Dead maple branches. Bratlleborough, Vermont. (J. C. Frvxt. 



Externally this fungus resembles smuU forms of Uuttrj/pclld^ oeiTWH'foruu'.i, from 

 which it is easily separated by the greenish color of the stroma. 1). betuliiui, whieit 

 also has a greenish stroma, difiers from this species in the larger size, dilTerenl form 

 and naked disk. 



Soiiosi'oiiiu-M Desmodii, 7V,:. — Si)ore balls irregular or sub-globose, compact, rough, 

 .0012- 0010 inch in diameter, color in the mass reddish-brown inclining to cinnamon ; 

 spores sub-globose, rough, .OOOti-.OOOT inch in diameter, four to ten in a group, not easily 

 separating from each other. 



Seeds of Bfsinodiim aciiunnaf/ui/i, DC. Closter, jSTew Jersey. C. F. Austin. Sep- 

 tember. 



I am not aware that any representative of this genus has before been detected in 

 the United States. Nor is it surprising that this species has so long escaped notice, for 

 the fungus is wholly concealed, being produced in the seeds while they are yet inclosed 

 in the ])0(1. For a time there is no externa; evidence of the i)resence of the fungus, but 

 at length a sligi.t discoloration of the part of the pod immediately over the atlected 

 seeds indicates that all is not rigiit within. 



The whole seed, except perhaps the tliin external coat, appears to be transformed 

 into the fiuigus spores. The color of these is similar to that of the sj)ores of S. Sajnyii- 

 '<;7"<F, but the spore nnisses are smaller and less easily sejiaraled into their component 

 spores. Every seed in a pod and nearly every pod on an atlected plant, so far as shown 

 by the siiecimens sent me, is attacked. From this it would ajjpear that the fungus must 

 be quite ell'ective in preventing the increase of this Dcsniodium by tlu; seed in localities 

 where it abounds. 



More about Lobkli.xs. — In the April number (1877) of the GAZiiiXE I mentioned 

 having found a white plant of /^•be/.i<( i<i/pJalitira T now have to rejjort not only a red 

 flowered plant of the same species, (dillering in no particular, except in color, from the 

 common form,) Ijut a remarkable plant which ai)pcars to be a hybrid between L. t^iipJd-
