Rank: Group or Clade

This MO Group represents the “Xeromphalina campanella/kauffmanii complex” of Aldrovandi et al.1 — species whose macromorphology is indistiguishable from X. campanella sensu stricto.
It includes at least: X. campanella, X. enigmatica, and X. kauffmanii,
X. 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.
X. kauffmanii has a distinct substrate — hardwood — and smaller spores (3–6 x 2–3 µm).

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.
