Sori on the leaves and culms, scattered, minute, roundish or oblong, up to 1 mm. long, pulvinate, surrounded by the cleft epidermis, black- brown ; spores clavate, usually truncate above, more rarely round- ed or conically attenuate, much thickened (10 — 16 fx), hardly constricted, tapering downwards, smooth,pale-brown, 40—56 x 10— 22 /i; pedicels hyaline, persistent, about as long as the spore. On Koeleria cristata. Very rare. Sejjtember and October, near Aberdeen (Prof. Trail). (Fig. 217.) There is much doubt about this fungus ; it was suspected by Winter, on account of the likeness of its teleutospores to those of P. Caricig, that the original specimens on which the species was founded grew not on Koeleria, but on Carer. It seems to have been recorded only twice, once by Morthier in the Jura, in spring on old leaves of the previous year, and once as above. The three figures quoted in the synonymy agree fairly well, but appear to have been all taken from the same material, viz. that gathered by Morthier, which according to Sydow may well be Koeleria and not I have examined the specimens, preserved in Herb. Kew, gathered by Prof. Trail ; they are undoubtedly Koeleria., they have split sheaths and, though not in flower, agree perfectly with specimens of Koeleria cristata from the Highlands, in the same herbarium. But they bear uredospores in slightly swollen epiphyllous yell
