Abstract

Type material and additional collections of 11 taxa of Gautieria described in Europe and North Africa have been studied, namely G. dubia , G. graveolens , G. morchelliformis var. globispora , G. morchelliformis var. magnicellaris , G. morchelliformis var. morchelliformis , G. morchelliformis var. stenospora , G. otthii , G. pseudovestita , G. retirugosa , G. trabutii and G. villosa . At the same time, morphological and genetic studies on recent and herbarium collections from several European countries have been carried out. This enabled clarification of sections within Gautieria and differentiation of 28 taxa, of which 21 are new to science. However, the deeper relationships and nomenclature changes related to the phylogenetic position of the genus Gautieria within Gomphaceae will not be addressed in this study because they would require a more complete molecular analysis together with that of related genera, e. g., Gomphus , Turbinellus , and the four subgenera of Ramaria . In addition, a lectotype for G. villosa var. villosa and reference specimens for G. graveolens and G. morchelliformis var. morchelliformis are selected, and the new combination G. morchelliformis var. dubia is proposed. Detailed descriptions, macro- and microphotographs and distribution maps of all taxa are provided, as well as extensive information on their ecology, chorology and phylogeny. A key is included to facilitate identification of taxa.
