L.quieticolor

is turning blue beneath the cap cuticle when cut but not as strong as L. hemicyaneus known from more mediterranean regions. L. semisanguifluus tends to grow on calcareous to neutral soil and usually is less big and more strongly colored than L. deliciosus … but you must be very experienced to tell them apart. L. deliciosus is very similar to L. sanguifluus but a little bit smaller and also the latex first turns orange. L. deterrimus never has a pitted stipe as far as I have found it. The greening is an aging process and can be found in all of em (more or less, mainly in L. sanguifluus and deterrimus). But I am ready to believe that there is much confusion left in this group and perhaps always will be despite DNA analysis because I am skeptical that material provided for analyses is always identified well.

A tricky group

There are so many contradictory descriptions of the species in sect. Deliciosi, even in this site (sometimes a particular species can be green or cannot, sometimes with a strongly pitted or not at all pitted stem, features that normally are used in keys to tell them apart):

I would have called this one quieticolor or maybe even deliciosus (at least the larger one), but I’m not sure what to think anymore..
