If, instead of going in search of goatsbeard and its attendant fungus, we turn our steps northward and enter one of the Highgate or Hampstead woods, where the pretty little wood-anemone (_Anemone nemorosa_) flourishes abundantly, and turn up the radical leaves, one by one, and examine their under-surfaces, we shall at length be rewarded by finding one covered with similar cluster-cups to those we have been describing as occurring on the goatsbeard, but far less commonly. Leaf after leaf will be found covered with the brown spots of another fungus called _Puccinia anemones_, with which nearly every plant will be more or less infected in the spring of the year; and at length, if we persevere, the anemone cluster-cup (_Æcidium leucospermum_) will be our reward (Plate I. figs. 4-6). The specific name will suggest one point of difference between the two fungi, as in this instance the spores are white, and somewhat elliptic. Probably this species is not common, as we have found it but seldom, though often in search of it. A nearly allied species has been found on _Anemones_ in gardens, having but few large teeth about the orifice, though not constantly four, as the name would indicate (_Æ. quadrifidum_). A walk through almost any wood, in the spring of the year, will reward the mycologist with another cluster-cup (_Æcidium_), in which the peridia are scattered over the whole surface of the leaf. This will be found on the wood spurge, giving a sickly yellowish appearance to the leaves, on the under surface of which it is found. By experience one may soon learn to suspect the occurrence of parasites of this nature on leaves, from the peculiar exhausted and unhealthy appearance which they assume as the spores ripen, and which will spare the labour of turning over the leaves when there are no distinct spots on the upper surface. _Æ. Euphorbiæ_ is found on several species of _Euphorbium_ or spurge, but we have always found it most abundantly on the wood spurge in the Kentish woods between Dartford and Gravesend. The spores in this species are orange, and externally it bears considerable resemblance to the goatsbeard cluster-cup, but the spores are rather smaller and paler, the teeth are less distinct and persistent, the subiculum is more thickened, and the peridia are more densely crowded. There is another group of species belonging to the same genus of fungi in which the arrangement of the peridia is different. One of the first of our native wild flowers, in making its appearance after the departure of frost and snow, is the little yellow celandine (_Ranunculus ficaria_).
