July—Septeni- This fungus closely resembles the Milesina on Polypodium vulgare, and was included under the name Milesia Polypodii B. and B. White. The markings on the spores of this and the allied species are more often of the nature of mere roughnesses than like the neat and regular ech inula- tion of the higher types {Puccinia, etc.)..
