The mycelium is often nearly obsolete, and the short pedicels so evanescent, that a rusty or sooty powder represents the mature fungus, infesting the green parts of living plants. This is more especially true of one or two orders. It will be most convenient to recognize two artificial sub-families for the purpose of illustration, in one of which the species are developed on living, and in the other on dead, plants. We will commence with the latter, recognizing first those which are developed beneath the cuticle, and then those which are super- ficial. Of the sub-cuticnlar, two orders may be named as the representatives of this group in Britain, these are the Sfhmro- nemei, in which the spores are contained in a more or less perfect peritheoiuna, and the Melanconiei, in which there is manifestly none. The first of these is analogous to the SpJusriacei of As- comycetous fungi, and probably consists largely of spermogonia of known species of Spliisria, the relations of which have not hitherto been traced. The spores are produced on slender threads springing from the inner wall of the perithecium, and, when mature, are expelled from an orifice at the apex. This is. Ceutlwspm-a phacidioides (Greville). the normal condition, to which there are some exceptions. In the Melanconiei, there is no true perithecium, but the spores are produced in like manner upon a kind of stroma or cushion.
