on an old stump, by Miss Lott, with Auricularia lobata, and Mrs. Gul. son, at Teignmouth, found A. mesenterica in equal plenty, both ladies gathered very large specimens of Agaricus (Clitocybe) giganteus, and characteristic ones of Boletus granulatus. Of the beatiful B. calopus we found three or four specimens in the spring in Epping Forest. The following species were found by Miss Lott, and forwarded to us amongst a quantity of others of less interest :- Agaricus (Pleurotus) subpalmatus, on some squared planks; this is a most beautiful species, the top of pileus is honeycombed, mottled, and gelatinous, and closely resembles, in texture, the flesh of Fistulina hepatica, when cut, it is beautifully coloured, has a rather strong but not unpleasant odour, and throws down a profusion of white spores. Polyporus cæsius, with verdigris-coloured spores, and tubes shaded with blue, plentifully on Larch, a most beautiful and characteristic species. Geaster fimbriatus, Peziza coccinea, Agaricus (Collybia) esculentus, abundant in Fir plantations, amongst the dead leaves, deeply rooting. A. (Tricholoma) terreus, and A. (Psalliota) cretaceus, (both found plentifully by Mrs. Gulson); we also found the latter species in many different places during the year, and A. (Lepiota) acutesquamosus.

In the late autumn, we found the "early summer” species A. (Amanita) vernus ; this is one of the most noble and beautiful, as well as poisonous of all the Agaricini. The list cannot be closed without a record of Paxillus Panuoides, found of enormous size and in large masses on rotten sawdust, by Mrs. Gulson, near Teignmouth.
