Language: french

Résumé: L'auteur propose, à partir d'une récolte faite en Suisse, la description et 1'illustration de Geopo­ra cooperi f. cooperi , un discomycète hypogé et tubero ï de. Les caractères du genre Geopora Harkness sont brièvement rappelés. La carminophilie des noyaux cellulaires, qui s' avère être une particularité générique, y est évoquée.

Summary: The author describes and illustrates a new record of Geopora cooperi f. cooperi from Switzerland in detail . G. cooperi is a rare hypogeous tuber-like discomycete. The characters of the genus Geopora Harkness are briefly summarized. The value of the carminophilic reaction of the nuclei is discussed.

First Bavarian record of Camarophyllopsis schulzeri.

Summary: First Bavarian record of the rare Camarophyllopsis schulzeri in an unfertilized grassland ( Hygrocybe- grassland). New microscopical characters from stipe and some notes about ecology.

Addenda to the "Fauna of Myomycetes" of Eastern Bavaria.

Summary: 17 species of Myxomycetes have been found for the first time in Eastern Bavaria and can be added to the list of species given in Krieglsteiner (1993). Comments on some species are given as well as SEM-fotos of the peridium inner side of Arcyria riparia and of the spores of Badhamia dictyospora, B. globosa, B. gracilis, B. viridescens, Physarum auriscalpium and P. penetrale. Colour photographs of Fuligo cinerea and Physarum auriscalpium are presented.

Summary: In the fourth instalment of his series on the Polypores of the region between the rivers Inn and Salzach (Germany, Upper Bavaria) and adjacent parts of Upper Austria, the author describes the distribution and ecology of the genera Abortiporus, Antrodia, Antrodiella, Bjerkandera, Ceriporia, Ceriporiopsis, Cerrena, Coriolopsis, Daedalea, Daedaleopsis, Datronia, Dichomitus, Diplomitoporus, Gloeophyllum, Gloeoporus, Ischnoderma, and Junghuhnia.

Morphology and population structure of the annelated species of Armillaria mellea s.l.

Summary: The morphological variation of basidiomata of the five annellated European species of Armil laria mellea s. l. ( A. borealis, A. cepistipes, A. gallica, A. mellea s. str. and A. ostoyae ) is presented in 8 colour plates and suitable characters for species identification were selected. We also identified the presence and size of Armillaria spp. genets at several forest sites in Bavaria. Up to four Armillaria spp. occurred together at a single site. The genets mostly had a diameter below 50 m, but also some larger genets were found (up to approx. 200 m diam.).
