fagi as synonym to penarius is just my conclusion.

Neither MycoBank nor IndexFungorum have an opinion..

in my main area to tell them apart. Each location where I have H. penarius in old sense is wooded with both beech and oak. Except one place where I think I have posted penarius with only oaks there. This should be penarioides, right?
So you mean penarius and fagi are synonyms?! Everything seems to get thrown over of late :(

to tell them apart if there’s both beech and oak in the area. I can’t possibly tell from the pictures if you have penarius (with beech) or penarioides (with oak) at this location.

Since penarius was originally described from Fagus woods, I must assume that fagi is a synonym.

Thanks for the reference Irene

Thanks for the reference Irene. It says “The Swedish and Norwegian localities are apparently northern outposts of a species widespread in central and southern Europe (e.g.southern Germany, France and Italy) and seemingly not rare. Bon (1977) states that it is common in Mediterranian oak woods.”

I beleive that the DNA tests have been made. If I understand it right, there are two european (penarius/fagi and penarioides) and one american taxon (sordidus) that are closely related:

Another taxa needing more DNA data to resolve

Irene, It looks like the DNA info is necessary to distinguish between these similar appearing species. Hygrophorus penarioides is recorded from Sweden, do you know if it has been recorded elsewhere? Hygrophorus penarius is recorded as found with both Oak and beech. Seems to me that it would take more DNA data from the mushrooms found with oak in different places to see if all the ones found with Oak match the H. penarioides DNA?

H. fagi

is that another name for Hygrophorus penarius?

(If it’s not H. penarioides which grows with oak..)
