Septotinia, A New Genus of the Ciborioideae

Among the many species commonly referred to Ciboria or Sclerotinia are several other groups having well-marked generic characters which wTarrant their segregation under new generic names, for example those species having a conidial stage of the Botrytis cinerea type. The genus to be described in this paper is characterized by a type of conidial fructification heretofore entirely unsuspected as belonging to an apothecial fungus. The apothecial stage, here for the first time reported, is typical of the Ciborioideae.2 But one species of this genus is at present known to the author.

North American Species of Sclerotinia—I

Some ten years ago the writer agreed to undertake the preparation of a monograph on the species of Sclerotinia for the North American Flora published by The New York Botanical Garden. A survey of the species reported from North America up to that time led the writer to assume that the undertaking would be a relatively simple one. His limited experience in taxonomic work was also doubtless an important factor in luring him into what promises to be a long and laborious though a most interesting and enjoyable investigation. It soon became apparent that to prepare a careful and reliable presentation of the North American species in this genus would require not only the collection and the examination in fresh condition of the morphology of as many of the forms as possible but also a comparative study of these forms in pure culture. Collecting soon uncovered undescribed species of Sclerotinia and species not heretofore reported from this country. The numbers of these have now increased to such an extent and the results of

Notes on the Geoglossaceae of Bermuda

The Geoglossaceae are well represented in Bermuda by some four genera and seven or eight species. The following notes are based on collections made over a period of seventy years. The earliest collection was that by H. N. Moseley, Naturalist of the British Challenger Expedition, in 1873. Berkeley (1, 2) published two lists of Bermuda fungi based on Moseleys collections which were later revised by M. C. Cooke and published by Hemsley (5). Only one species, Trichoglossum hirsutum (Pers.) Boud. (recorded as Geoglossum hirsutum Pers.), was reported. Extensive collections of fungi were made both by Dr. B. 0. Dodge in 1911 and by Dr. F. J. Seaver in 1912. A list of these, together with some additional species collected by Dr. Stewardson Brown and Dr. N. L. Britton, was published by Seaver (6, 7). These collections added Geoglossum nigritum Cooke and Trichoglossum hirsutum f. Wrightii Durand to the list. The latter was raised to specific rank by Durand (4) after an examination of Bermuda material and named Trichoglossum Wrightii Durand. A further record, Geoglossum pumilum Winter, was added by Durand (4) and was later noted by Seaver (8). Further collections were made by H. H. Whetzel during the years 1921 and 1922, whilst acting as the first plant pathologist appointed to the Bermuda Department of Agriculture. Additional collecting was done by Lawrence Ogilvie, appointed plant pathologist in 1923, in cooperation with the junior author and with Dr. F. J. Seaver who revisited the Colony in 1926. Dr. Seaver revisited Bermuda on two further occasions during the autumns of 1938 and 1940 and, in company with the senior author, made further collections of fungi. Over thirty separate collections of Geoglossaceae are listed from Bermuda in the Herbarium of the Department of Plant
