BRITISH FUNGI. 179 



This curious fungus we have referred to the above with some 

 hesitation, never having seen a specimen of the plant described by 

 Riess, with the description of which the Hereford specimens 

 appear to agree in many points ; the spore threads are decidedly 

 coloured brownish, joints about -01 m.m. dia. 



Puccinia silenes. Rahh. Fung. Eur., No. 1783. 



Spots yellowish ; sori roundish or oblong, scattered or aggre- 

 gated ; pseudospores elongated, elliptical, slightly constricted at 

 the septum, on short pedicels, brown ; stylospores globose, smooth. 

 — Puccinia Lychnidearwn, Fckl. 



On leaves of Silene inflata. Basingstoke (R. S. Hill). 



This is quite distinct from other species on Caryophyllaceous 

 plants, the pseudospores being of a different character, each cell 

 rounded above, or sometimes somewhat obtusely triangular, 

 •03--032 X "018 m.m. ; whilst the stylospores (Uredo form) are 

 globose, smooth, and about '02 m.m. diam. 



Puccinia Andersoni. B. 4' ^'>'- Ann. N.H., No. 1464. 



Spots epiphyllous, orbicular, surrounded by a brown border ; 

 sori hypophyllous, minute, crowded, almost concealed by the 

 pubescence of the leaf; pseudospores oblong, constricted in the 

 centre, obtusely apiculate. 



On leaves of Cnicus heterojyhyllus. Glen Ogle. June. 



Pseudospores very like those of P. discoidearwn, as figured by 

 Corda. 



Puccinia Fergussoni. B. <£• Br. Ami. N.H., No. 1465. 



Spots pallid ; sori minute, crowded in orbicular clusters ; pseudo- 

 spores oblong, obtusely apiculate. PI. 49, fig. 10c. 



On leaves of Viola palustris. New Pitsligo (Rev. J. Fer- 

 gusson) . 



Very different from P. violarum, not only in the minute crowded 

 sori, but in the elongated spores. — B. ^- Br. So closely resembling 

 Puccinia Asari that unboubtedly the specimens published in 

 " Fungi Britannici," No. 110, belong to this species. 



This is one of at least four good species of Puccinia that occur 

 on leaves of Viola; the other British species is P. Violarum, ioundi 

 also in the United States. PI. 49, fig. 10 a. The pseudospores 

 are about ■02--03 x '013-016 m.m. Another species occurs on 

 Viola hastata* in North America, with pseudospores •035-'04 X 

 •02-'025 m.m., a very considerable difference in size. The fourth 

 species is P. alpinu, Fckl., on Viola bijlora, with still longer and 

 rough pseudospores. PI. 49, fig. 10 d, 



Puccinia senecionis. Lib. Fungi Exsic, No. ^2. 

 Sori gregarious, circinate, minute, punctiform, convex, covered 



* Puccinia liastata. Cooke. — Ampbigenis ; acervulis sparsis, pulverulentibus, 

 atro-brunneis ; pseudosporis ellipticis, leniter constrictis, Isevibus ('035-04 X 

 •02-'025 m.m.), breviter pedicellatis ; stylosporis globosia, Isevibus ('02 X *022 

 m.m.), ad foliis Violce hastatce. Maine, U.S. (E. C. Bolles, 68). PI. 49, fig. 10b.
