ZitatOne of the goals of the editors of Cantharellus News is to provide, together with the nomenclatural data of the different taxa, a good number of high quality colour photographs of Cantharellus species from all over the world.
ZitatAs the microscopical diversity among the various species in the genus is rather limited, general field characteristics such as overall color, size and shape have always taken a very important place in the delimitation and identification of species.As a consequence, the use of molecular data to delimit species in Cantharellus may result in a reduction rather than a multiplication of accepted species, contrary to what can be observed in other genera of the cantharelloid clade, such as Hydnum (Feng et al. 2016). This is here particularly well illustrated by the extreme example of the newly described C. velutinus (Buyck et al. 2016e), the variability of whichhas met with much disbelief among colleagues. It is therefore not surprising that recent revisions of European chanterelles (Olariaga et al. 2015, 2016) resulted in a rather impressive reduction of the currently accepted European Cantharellus from 24 (Eyssartier & Buyck 2000) to merely eight species, each of these being highly variable in overall color, as well as in size and general habit.
ZitatThe controversial boundary between Cantharellus and Craterellus Pers.: Fr. (Corner 1966; Petersen 1971), both classified in Cantharellaceae, has been resolved with aid of molecular data (Dahlman et al. 2000; Moncalvo et al. 2006). Compared to Craterellus, Cantharellus is featured by having bicyclic carotenoids and, with few exceptions, basidiomata with a solid stipe (Buyck et al. 2014).
