246 A. Ba.rc\a.j~Descript{ve List of the Urodineas [No. 2, 



This fungus on A. Wallichii is not common. It forms linear black 

 pustules on the lower surface of the leaf. I have not found uredosporea 

 on this host. The teleutospores are brown, rounded at both ends, 

 equally divided into two by the septum, not constricted at the septum 

 and thickened at the free end. Freshly gathered spores moistened 

 measure on an average 40 /x in total length and 18 /a at the septum. The 

 thickening at the free end measures about 8 jw, in depth. The free end is 

 usually rounded, but sometimes more or less pointed. The spores break 

 off from their beds with a long piece of stalk adhering (Fig. 11, PI. XllI). 



Eemarlcs. — I have grouped these two fungi together, as the teleuto- 

 spores resemble one another closely ; but subsequent observation may 

 prove them to be distinct. It is I believe a new species.

on Andropogon tristis, Nees. 

 This is not a common fungus, and I have only found teleutospores. 

 Pustules of these spores are formed on the lower surface of the leaf ; 

 they are linear or oval, tending to coalesce, and very numerous on each 

 attacked leaf. The spores are firmly adherent, in long stalks, brown, 

 rounded usually at both ends, and thickened at the free end. The spore 

 is slightly constricted at the septum (Fig. 13, PL XIV). Freshly gather- 

 ed spores, when moistened, measure from 34 to 41 in total length ; the 

 upper cell varies from 17 to 21 /.i and the lower from 16— 20 /u. The 

 width at the septum is 16 to 22 fj., and the apical thickening about 8 in 

 depth, 



BemarJcs. — Two species of Puccinia on species of Andro^iogon are 

 described in America,* one referred to P. Phragmitis (Schum) and the 

 other to P. Andropogi, Schw. If the Indian species is identical with 

 either, it is more probably with the latter, and I have therefore named 

 it accordingly for the present. 



19. PncoiNiA Anthistiem, nov. sp. 



on A7ithistma anathera, Nees.f 

 The leaves, haulms, and glumes of this grass are often attacked by 

 a fungus, bearing large conspicuous beds of sooty black teleutospores, 

 sometimes so confluent, and so largely involving the surface area of the 

 part attacked as to suggest the idea that it is one of the Ustilaginew. 

 Small linear or oval beds are also met with, and indeed the large beds 

 are the result of the coalescence of these primarily small bods. The

t I am not quite certain that this host has boon correctly determined : it may 

 prove to be a species of Bromiw,
