Giacomo Bresadola and the genus Inocybe: his diagnoses and illustrations

The study with comment deals with the analysis of the treatment of the genus Inocybe made by G. Bresadola during his whole life. The complex of analogous studies dealing with species seen only in countries other than Italy, or issued in plates without any comment, is excluded from the present work.

Distribution and ecology of Tricholoma sulphurescens and Tricholoma bresadolanum in the Nordic countries

The authors give descriptions of two species of Tricholoma which are rare in the Nordic countries, including comments on the ecology and distribution. T. bresadolanum is here reported for the first time from the Nordic countries, it has been found in two localities in Sweden on the island Öland. The habitats (boreo-nemoral Quercus forest) are quite similar to the habitats of the species in Southern Europe. Tricholoma sulphurescens is known from about twenty localities in Fennoscandia. These can be divided into three separate groups each representing a different distribution and ecology. The southern group contains records from nemoral and boreo-nemoral broadleaved forest. The central group contains records from boreal forest dominated by Picea abies and Betula spp. The northern group contains records from dry, northern boreal forest dominated by Pinus silvestris, Betula spp., Populus tremula and Salix spp.

Des expériences sont en cours depuis 1991 à Paris, pour apporter l'aide des champignons mycorrhiziens aux arbres d'ornement placés dans un milieu urbain difficile (pollution, piétinement, etc.). Des tilleuls argentés (Tilia tomentosa) ont été inoculés avec le mycélium de trois espèces, Paxillus involutus, Laccaria laccata et Cenococcum geophilum. Leur présence entraîne une amélioration significative de la vitesse de croissance des arbres, ainsi que de la qualité de leur feuillage: les feuilles des plants inoculés jaunissent moins vite et tombent plus tard. De nouvelles recherches sont prévues pour choisir les espèces et les souches les plus performantes.

What is Omphalia scyphoides ss. Bres.?

The identity of Omphalia scyphoides ss. Bres. (Iconogr. Mycol. 260/1) is discussed. It is shown that this taxon has to be regarded as a true Omphalina-species, which should be cited Omphalina scyphoides (Fr.) Quél. ss. Bres. non Fr., non Quél. The main features of this fungus are summarised as following (based on Bresadola's and own observations): Completely white fungus, sometimes becoming partly very pale straw yellow when old. Cap margin involute. Pileipellis slightly felted. Gills rather crowded, narrow and often forked. Stipe always central and never distinctly short, often with small basal bulb. Taste and smell none. Apparently rare species growing on bare ground or among various mosses. Differing from similar Agaricales by well developed lamellae, small, smooth, inamyloid, hyaline spores and the lack of cystidia and clamps. This "forgotten" taxon has surely often been confused with Omphalina (Gerronema) albida or perhaps Omphalina (Gerronema) mutila too.

Mycena bresadolana, a new species in sect. Rubromarginatae

A Mycena of the section Rubromarginatae, differing by at least 6 characteristics from the neighbouring species with which its affinities are discussed, is described as a new species. Very probably, this is the same taxon as Mycena rubromarginata var. xanthopoda Bres. However, the lack of the typus exsiccatum, for the Bresadola's variety, makes impossible the confirmation of this identity. In spite of that, the authors, intending to dedicate this species to Giacomo Bresadola, have found that the epithets xanthopoda, xanthopus and bresadolae already are used in the genus Mycena, but that M. bresadolae is a nomen dubium never used for a known mushroom by the modern specialists. Therefore, it is possible to propose the name Mycena bresadolana Robich & Neville sp. nov. without ambiguity. A practical key of the european species of the section Rubromarginatae is proposed.
