Pretty clearly X. enigmatica I think

as the blast results with curated sequences of PNW X. enigmatica from the referenced paper are 99.9%-100% whereas the match with curated sequences of X. campanella from the same area are only 96.5%. According to the paper: “Average ITS base-pair variation within X. enigmatica was 1.52%.” And “Barcode gaps (average percent divergence (Hebert et al. 2003)
among X. campanella, X. enigmatica and X. kauffmanii exceed 3%, often considered an indication of separate taxa (Hughes et al. 2009).”

The toughest job after blasting is verifying that the GenBank sequences are properly labeled. I would love a copy of this paper if you wouldn’t mind emailing it to me. I will be sequencing material in this group would love to have it as a resource.



Comparing sequences to Aldrovandi et al. [edited]

After Pulk’s Comment below, Matt Gordon’s ITS sequence was posted. I just BLASTed it.
Here’s how the highest scoring hits match with Aldrovandi et al.1

Hit #




Genbank name


1 AB711999 99% 100% Basidiomycota enigmatica 4 PNW 3
2 HQ604741 99% 100% X. campanella enigmatica 4 PNW 3
3 HQ604742 99% 100% X. sp. enigmatica 4 ENA 1
4 KC581312 99% 94% X. campanella enigmatica 4 PNW 3
5 HM240545 99% 94% X. campanella enigmatica 4 PNW3
6 KC581311 97% 94% X. campanella campanella 3 n.a.

So, based on Aldrovandi’s trees and only ITS, this Observation is more likely Xeromphalina enigmatica than X. campanella. But is barcode alone reliable: hit #6 is pretty close. Probaly closer than other ITS sequences ID’d by Aldrovandi as X. enigmatica, but I don’t have time to run that down.

X. campanella indistinguishable from X. enigmatica without mating studies or DNA

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.
