Book Description
Excerpt from The Polyporaceae of Wisconsin This great family of fungi is represented in Wisconsin by a large number of species, belonging to all the commonly accepted genera except Cydomyces. Many of them are common in all parts of the state but a few have so far been found only in certain regions. Polyporus volvatus, for example, is of course found only in the northern part of the state where its host, the pine, grows in considerable abundance. Many other species that have been collected only in the northern part of the state will probably also be found in the southern part, as their hosts, and the conditions necessary for their growth, are present in both regions. For example, Fomes marginatus grows on various deciduous trees, but it has thus far not been collected in the southern part of the state with the exception of one specimen which was found growing on a hickory stump in Madison., The group includes parasitic, saprophytic and terrestrial species. To the latter belong the Holeti, Boletini, Strobxlomyces and Form terrestris. The great majority, however, belong to the first two groups and it is not yet clear as to many wood inhabiting species whether they are in a strict sense parasitic or saprophytic. The collections on which the following account is based are now in the herbarium of the University of Wisconsin. They were made during a period of six or seven years by a number of collectors. By far the largest number of species was collected by the writer on special excursions into our northern forests. The brief account of the distribution and relation of the polypores to various decays in timber trees is largely the result of a special study of certain of our northern forest regions which were worked over in the summer of 1904, while the author was employed as a special agent of the United States bureau of Forestry. Abundant specimens of wood in various conditions of decay were collected and later worked over microscopically.
