. The British rust fungi (Uredinales) their biology and classification. Rust fungi. 184 PUCCINIA verruculose or distinctly verrucose-reticulated, even sometimes nearly smooth, brown,, 28—46 x 18—30 ytt; pedicels hyaline, thin, short, deciduous. On Gicida virosa. Rare. Mentioned by Plowright in his arrangement of the British species, Trans. Brit. Myc. Soc. ii. 26; he assigns spermogones to it as well. I have seen no specimens. The fungus is similar to P. Smyrnii in its secidia and teleutospores, but differs in the presence of uredospores. Description after Sydow. Distribution : Central and Nort
