Abstract [en]

Wood-inhabiting fungi were collected on different trees in 99 loca-' lities of alder woods, dominated by Alnus incana or occasionally A. glutinosa, in N-C Sweden and C Norway. Most of the localities are situated near the east coast of Sweden where the prevailing land elevation creates conditions suitable for colonization by alder. The remaining localities are mainly found in the inland parts of Sweden and Norway, along streams, in ravines etc. The investigated localities are briefly described as to their general vegetation, and a regional survey of the alder forests is given.

The number of collections of Aphyllophorales amounts to approxi­mately 5,000, comprising 286 species. The following new combinations are proposed: Hypoohnicium polonense (Bres.) Strid, H. pruinosum (Bres.) Strid, Phlebia lindtneri (Pil.) Parm. and Sistotrema hete- roncmum (John Erikss.) Strid. Seven species are collected as new to Scandinavia, viz., Botryobasidium aure urn3 Ceratobasidium stridiit Hyphoderma orphanellum, Hyphodontiella multiseptata, Hypoohnicium pruinosum> Phlebia lindtneri and Tubuliorinis effugiens, and approxi­mately 85 additional species are reported for the first time from the investigation area. Six specimens of Cortioiaoeae have remained undetermined but are included in the species list. Most of them represent species new to science, but they are not, for different reasons, described as new species. Preliminary, one of them is re­ferred to Ceratobasidium, one to Hyphoderma and two to Sistotrema.

All species are presented in a list with annotations on their aut- ecology, distribution in Scandinavia and, when needed, taxonomy. The records of species collected more than once are mapped on 196 maps.

The ecology of wood-inhabiting Aphyllophorales in alder forests is discussed, including habitat conditions (decay, moisture, tempera­ture, soil conditions), distribution of fungi on different host trees, succession of fungi and some regional-ecological traits.

The distribution of fungi is summarized by a grouping of represen­tative species into flora elements which, in turn, are compared to those that have been proposed for vascular plants.
