Excerpt from Memoirs of the American Academy of Arts and Sciences, 1896, Vol. 12IN the fourth volume of the Memoirs of the Boston Society of Natural History (no. VI, April, the writer published an account of the American forms belong ing to the family of Entomophthoreae, with notes on all the species then known, which was intended to form the first of a series designed to include all the American fungi parasitic on insects. The subject was suggested to me by Professor Farlow, while I was a student in his laboratory, as one promising data of sufficient interest to furnish material for a doctor's thesis. The Entomophthoreae, however, having proved ade quate in themselves to fulfil this requirement, the remaining entomogenous forms were laid aside in the hope that, at some future time, the original plan of a complete monograph might be carried out. In the paper just mentioned, a brief summary was given of all the fungi characterized by this peculiar parasitism, and, in addition to the family of Entomophthoreae, several groups were in a general way distinguished. Of these one comprises the entophytic and probably commensalist Schizomycetes rep resented by the genus Enterobrus and its allies, to which might be added certain lower forms of the same order supposed to give rise to contagious diseases among insects, a second includes the perfect and imperfect or isarial conditions of the entomogenous species of the genus Cordyceps and its allies while a third embraces all the members of the then small and little known family of Laboulbeniaceae. To these should be added a few miscellaneous forms parasitic on insects, and perhaps, also, such fungi as are found in nature only on the remains or excreta of certain insects. The last, how ever, since they are saprophytic, cannot be called entomogenous in the more strict sense of the term.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
