The number of collections and geographical distribution of Morchella fluvialis sp. nov. suggest that this species is widespread along rivers of Spain, associated to riparian forests composed of Fraxinus angustifolia or F. excelsior and occasionally Ulmus minor. This habitat is shared by other morel species of wider European distribution, especially M. vulgaris and M. esculenta from which it differs by an assemblage of morphological features. Its apparent restriction to riparian habitats in Spain makes it a vulnerable species which requires monitoring.

For morels this task is especially difficult because of high morphological stasis and high plasticity of apothecium color and shape. Here we propose a nomenclatural revision of true morels (Morchella, Pezizales) from Europe and North America, based on molecular phylogenetic analyses of portions of the genes for RNA polymerase II largest subunit (RPB1) and second largest subunit (RPB2), translation elongation factor-1α (TEF1), the nuc rDNA region encompassing the internal transcribed spacers 1 and 2, along with the 5.8S rDNA (ITS), and partial nuc 28S rDNA D1-D2 domains (28S). The 107 newly sequenced collections were from both continents, including 48 types, together with previously published sequences. Names are applied to 30 of the 65 currently recognized genealogical species. Results of the present study revealed that the number of Morchella species in Europe (n = 21) is nearly identic...
