Lactarius deliciosus or deterrimus?

[timhale197200]

Please help. I am a bit confused as to which Lactarius these are, after reading Rons three unidentified fungi post. My initial thought was that they were deliciosus, but i am not sure now. Any pointers in the right direction greatfully recieved.




All found under conifers.
Thanks.

hi

in addition to the comments Andreas has made I would add that deliciosus usually has a more strongly marked (scrobiculate) stem

a key difference is the mycorrhizal host: deliciosus with Pinus and deterrimus with Picea

that bottom picture looks rather like a spruce plantation?

the specific name deterrimus derives from the Latin adjective meaning 'worst' ('worse' is 'deterior' - hence deteriorate: to become worse . . . .) those names generally mean something!; one assumes the worst epithet is a reference to its inferior quality as an edible species

lesson over

cheers

Hello,

exactly Chris! The non-scrobiculate stem is THE key character of Lactarius deterrimus. And yes, it is the worst of all those red milking Lactarii, also a lot of peolpe like it nevertheless.

best regards,
Andreas

These specimens of L. deliciosus were found this afternoon in a pine plantation and show the scrobiculate stem (shallow depressions, grooves, or pits). The orange milk of deliciosus turns green when dry whereas that of deterrimus turns wine-red after a couple of minutes.
