Name: Xeromphalina campanella group
Xeromphalina campanella can be distinguished from X. enigmatica only by mating studies or DNA sequencing. They’re effectively identical in macroscopic features, microscopic features, chemical features, geographic location, and substrate preference.

Hopefully, future studies will include more than just the ITS loci. Protein coding genes like the tef1 may provide more useful information for more recently evolved species. Firm conclusions regarding speciation cannot be drawn from the Aldrovandi et al. paper because there are alternate explanations for the results presented. Hybridization is suggested (perhaps due to the variability of the ITS) but has not been proven.
