IX.—Notices of British hypogœous Fungi

several interesting discoveries have been made amongst the hypog~eous species, which it is desirable should at once be recorded.It is to be regretted that the memoir of Messrs. Tulasne has not yet been published, though presented to the Academy.Two recent opportunities however of inspecting their drawings, and the communication of many new and rare species, as also the receipt of a very complete collection of authentic specimens from Vittadini and Corda, have enabled us to ascertain some points which were previously uncertain.Doubtless many more species will reward the continued researches in a field which is almost new to British botanists, and there is every reason to believe that the greater part of the species are pretty generally diffused.The list of indigenous species in proportion to our flora is already as large as in France or Italy.It would not be fair to omit recording the active researches of Mr. Thwaites, to whom we are indebted for many valuable observations.I.
