210 MICROSCOPIC FUNGI. 



common. Summer. The Uredo spores are Uredo Saxifraf/arum, 

 DC. 



PticciniaClirysospleiiiijGrev.GoLDEN-SAXiFRAGEBRAND; 

 sori of various sizes, few together and conflueut, pale-brown ; 

 spores long, somewhat waved, much attenuated at either ex- 

 tremity ; peduncle elongated. — On the under surface of the leaves 

 of Chrysosijlerdum oppositifolium. Rare. 



Puccinia Calthse, Lk. Marsh-Marigold Brand ; spo^s 

 brownish ; sori small, subrotund, convex, surrounded by the 

 ruptured epidermis, scattered ; spores obovate, attenuated below, 

 slightly constricted; peduncle very short. — On leaves of Marsh 

 Marigold. Spring. Hare. 



Puccinia Noli-tangeris, Corda. Balsam Brand ; sp^^i:* 

 irregular, confluent, brownish; sori gregarious, reddish- browij; 

 spores oblong, obtuse or attenuated, distinctly apiculate, brown ^ 

 peduncles rudimentary. — On leaves of Impatiens noli-tangire. 

 Gathered at Albury, Surrey, by the E.ev. L. Jeuyns. The Uredo 

 spores are Trichobans Impatientis. 



Puccinia Violarum, Lk. Yiolet Brand; spots yel- 

 lowish; sori bypogenous, small, crowded, covered with the 

 epidermis, then surrounded by it ; spores brown, elliptic or 

 broadly elliptic, slightly constricted— On Violets. Autumn. 

 Common. The Uredo spores are Trichobasis Violarum. 



Puccinia Fergussoni, B. and Br. Spots pallid; sori 

 minute, crowded in orbicular clusters ; pseudo-spores oblong, 

 obtusely apiculate. — On leaves of Viola palustris. Wales. 

 Scotland. 



Puccinia Lychnidearum, Lk. Lychnis Brand ; spots 

 yellowish ; sori subrotund or oblong, unequal, scattered, rarely 

 conQuent; spores white, at length brown, elongated, oblong, 

 slightly constricted. — On leaves and sterns of Lychnid<B^ Sugina 

 procumbens. Autumn. Common. The Uredo spores are rWe/^o- 

 basis Lychnidearum. 



Puccinia Mcehringise, Fuckel. It is very doubtful 

 whether this deserves to rank as a species distinct from P. Lych- 

 nidearum^ Lk. I think not. The pseudo-spores are rather shorter 

 than in the last-named species, and the pedicels are very long ; 

 otherwise it does not appear to differ from the typical form. — On 

 Mcchringia trinervis. June. 



Puccinia SpergLilse, DC. Hardly seems to be a distinct 

 species. — On Spergula arvensis.
