Updates to taxonomy

Matheny et al. (2010) nullified the decision of Dahlman et al (2000) to combine Craterellus cornucopioides with Craterellus fallax, sighting evidence that the two have different colored spore prints, the nLSU DNA in Dahlman’s study was NOT identical between the species, and Matheny et al’s ITS DNA was able to reliably differentiate them.

“An LSU sequence (AF105299) of Californian C. cornucopioides is identical to a sequence of C. fallax from Mississippi (AF105305), but differs at three positions (all gaps) compared to material from Massachusetts (AY700188). However, according to Arora (1986), C. cornucopioides from California has a whitish to pale yellow spore print and smaller spores than C. fallax from eastern North America. Careful morphological scrutiny and ITS or mtLSU sequence analysis should be helpful to
determine the taxonomic status of C. cornucopioides in California and southern Oregon,…”

I need to vastly expand my resources.

but there are at least three separate species in the complex, genetically quite different from each other, cornucopioides mainly a european species. I think the text in MushroomExpert is outdated (2006)…

Take a look at this:

If I understand it right, there’s a tiny one that has been named “Pseudocraterellus hesleri”.

The seperation of those 2 species confuses me…

From Mushroom Expert:
“Thus, we can forget about ‘Craterellus fallax,’ separated on the basis of its salmon buff or yellowish spore print… … If your Craterellus has a smooth under surface and is not a tiny little thing (under 2 cm across), the odds are now high that you have collected Craterellus cornucopioides.”
