18. TRICHOBASIS FALLENS. Spots obliterated. Sori amphigenous, 
numerous, scattered, subrotund, brown, surrounded by the remains of 
the ruptured epidermis. Spores subovate, pedicels short, hyaline, 
evanescent ; epispore verrucose.—Uredo fallens, Desmz. Ann. des Se. 
Nat. ser. 3. iii. p. 857 ; Pl. Crypt. Exs. ed. i. n. 1325. ed. ii. n. 725.— 
On leaves of clover, ete., Sept. 1865. Neatishead, Norfolk, and else- 
where. On Vicia sepium, intermixed with the Puccinia hereafter de- 
scribed, near Liverpool (R. G. M‘Leod).—Though this is undoubtedly 
nothing more than the Uredo-form of Puccinia fallens, 1 have preferred 
assigning it a name until a revision of the whole of this Order takes 
place, and the forms under which the same species occurs cease to be 
designated by different names, and become associated together under 
their proper designation. : 
19. PUCCINIA FALLENS, #.sp. ; maculis obliteratis ; soris amphigenis, 
paucis, sparsis, rotundatis; sporidiis obovatis, longe pedicellatis, 
fulvis, vix constrictis, episporio levi.— On Vicia sepium, near Liver- 
pool, autumn, 1865 (R. G. M‘Leod). Sori few and small, scattered, 
intermixed with pustules of Zrichobasis. Sporidia obovate, on rather 
long pedicels of a tawny colour, and slightly constricted at the septum. 
Epispore smooth.—Apparently not common, and as far as I can ascer- 
tain, undescribed. ; 
Puccrnta VrgGaUREA, Lid. Spots orbicular, pallid, then yel- 
lowish. Sori blackish-brown, minute, punctiform, shining, clustered, 
nearly stellate, convex. Sporidia oblong, subconstricted, yellowish- 
brown above, attenuated and yellowish-white below. Peduncles short.
