Only known in the uredo-stage, but closely allied to M. Blechni. The name, Uredo Scolopendrii, has been used to include many other species. Besides these parasites on Ferns, Plowright also records under Uredo Polypodii (p. 256) a fungus on Adiantum Capillus-Veneris. If this is correct, it was probably Hyalopsora Adiunii-('<i^illi- V<-neris Sydow (Annal. Mycol. 1903, p. 248), which, I am informed by Herr H. Sydow, occurs in Istria and North Italy. It is quite possible that two others may be found in Britain, viz. Milesina Kriegeriana Magn. on Aspidium spinxdosum and Uredinopsts Micina Magn. on Polypodium Phegopteris, but I have seen no British specimens. The latter is so likely to occur here, that it is advisable to give a description of Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Grove, W.
