Blackening Hygrocybes

It’s possible, but the most recent molecular work does not show that. Hygrocybe conica represents a species complex of at least 11 species worldwide. Hygrocybe conica sensu stricto is from Germany and its range seems limited to Germany. Here is the paper. http://fungi.myspecies.info/...

at least one other for sure in Santa Cruz – a dry capped, small, grass-dwelling species that may in fact be the true H. conica of Europe (probably imported species).

According to a recent phylogenetic tree, there is a look alike to the native H. singeri in the west, probably undescribed at this point, perhaps H. olivaceoniger sensu auct. amer. The European names should not be used for this group in north America.

I don’t believe in it as a separate species (I think it’s a color morph of singeri), but Noah thinks it might be different – you’ll have to ask him for more details.

I found a green-yellow specimen next to a more normal colored specimen as well: http://mushroomobserver.org/194053

Viscidity of singeri

varies, I think it has been confused because the original description distinguished it based on that character. I think it has to do with the water content of the fruitbody as well as situations where the cap slime gets transferred to the stipe during expansion.

It may be that there is more than one common species of blackening, conical yellow to reddish waxy cap (see H. olivaceoniger) in California, but I doubt it. Yesterday I found some l H. singeri that were greenish-yellow (like olivaceoniger) as well as one that was bright red fruiting right alongside more typically-colored H. singeri.

Stipe not viscid…
