Summary. Berkeley's twenty agaric records for Zanzibar are revised and two new combinations Leucoagaricus rhodocephalus and Galerina periniana are proposed. In 1885, Berkeley, at the age of eighty-four, published a brief account of a collection of fungi sent to him from Zanzibar by his daughter, Miss Ruth Berkeley. These were mostly species of Agaricales which were collected one year earlier, probably in and around Zanzibar township. Twenty agaric species were listed of which ten were described as new and the rest assigned to European taxa. Although this was one of the very few papers dealing with East African fungi, the list has been largely overlooked, except for the description of Agaricus trisulphuratus Berk., which is now known to be common and widespread throughout tropical Africa. The very brief diagnoses provided by Berkeley have made a revision based on modern taxonomic criteria necessary. Most of the specimens were accompanied by a watercolour sketch so that it is sometimes possible to supply additional information about the appearance of the fruitbodies as well as the micro-characters. In a few cases no material is preserved and the record is represented only by a sketch. As the short account by Berkeley is little known and not readily available, in the present work each individual revision is prefaced with the original description. The species are arranged in the order of original publication. I. Agaricus missionis Berk. in Ann. Mag. Nat. Hist. V, 15: 384 (1885). Lepiota missionis (Berk.) Sacc., Syll. Fung. 5: 55 (1887).

This material was studied as a preparatory step to a survey of the genus Lepiota (Pers. ex Fr.) S. F. Gray in Australia. Most of the specimens had been forwarded to Kew prior to the year I900 and the condition of the material was frequently poor. In some cases additional information in the form of a short description and/or a pencil sketch was available. The accuracy of the specific epithet attached to each group of specimens has been checked. Specimens which were incorrectly placed were identified only if the evidence was sufficiently distinctive. The purpose of these investigations was primarily to investigate the reliability of the early records, but new data have been recorded when the material was of such a nature as to be

The fungi enumerated in the present list consist of the Basidiomycetes collected by Professor F. L. Stevens in the Hawaiian Islands during the summer of 1921, and of the fungi in the Bernice Pauahi Bishop Museum Herbarium which were brought to the United States for study in connection with the Stevens collections. Most of the specimens from the Museum were collected by Professor C. N. Forbes. The 150 numbers which comprise this lot of specimens belong to 61 species; more than three-fifths of the specimens and nearly half of the species are Polypores; 11 per cent, or the 7 species, Lepiota xylophila, Crepidotus rhizomorphus, Fomes hawaiensis, Fomes fasciculatus, Poria fasciculata, Corticium granulare, and Epithele hydnoides, are regarded as indigenous. Lepiota xylophila Pk. and Fomes hawaiensis Forbes were described several years ago; the other 5 species named above are now described as new. Of the species fully determined, which occur in other countries besides the Hawaiian Islands, about 43 per cent are of cosmopolitan distribution, 13 per cent are confined to tropical regions of both America and Asia and East Indies, 2412 per cent occur in the Philippines and East Indies but not in America so far as known at present, and about 6 per cent of the species are regarded as indigenous members of the fungal flora of the north temperate region of North America. Hence the purely North American component in the higher fungal flora of the Hawaiian Islands is hardly a fourth as great as that of Asiatic, East Indian, and Philippine sources, so far as the present small number of species show. In accordance with the instructions received, a portion of each specimen, if sufficiently ample, has been retained in the Missouri Botanical Garden Herbarium and the remainder returned to
