Lactarius quieticolor?

[SheffieldLass]

I found these today in grass under pine (I think Pinus sylvestris but will go back and check as there is also supposed to be Corsican pine in that compartment as well).



Taste mild, milk orange turning reddish quite quickly, and where I'd broken off a bit to nibble, noticed it had turned greenish. That picture was photographed on my lawn when I got back, first photo was insitu. Using Funga Nordica it seems to key out to Lactarius quieticolor, and it seems to look right for that. I've not yet looked at the spores. Do I need to or are the macro details pretty conclusive. If it is L quieticolor it would appear to be the first record for Yorkshire.

Hallo Mel,

if this would be my finding, I would id it as L. quieticolor and would not microscope it. To me it seems determined.

best regards,

Absolutely . . . . indeed the first record within an area bounded in the south by a line from Norfolk to North Wales and in the north by the Scottish Highlands NBN Gateway: Lactarius quieticolor grid map

I wonder whether it is on native Pinus in Scotland or always on introduced pines . . . and hence an alien

keep up the good work Melanie (told you that your area would prove productive - despite having had a relatively recent fungus flora published . . . ); do keep material - I'm sure you will

great stuff - and thanks to Andreas as well

I'm not so sure he will be ... I keep adding new things to mess up the Yorkshire list he's producing .

I do seem to be on a bit of a roll at the moment. Don't know whether the weather has brought about unusual things or whether it is a good time of year to be looking because others haven't looked much at this time of year. There is certainly a big flush on at the moment.

no problem, kid - you keep adding them!

that's the advantage of digital lists - it's not as though it's going to be a published book - much easier to add to (and take away on occasion . . . .)

What, No book! But my records for you include the images too

Very interesting thread! But for the benefit of us relative newbies, could you explain what about this lactarius makes it obviously quieticolor rather than deliciosus? Are there other similar-looking orange lactarii besides deliciosus, deterrimus and (now) quieticolor? Here in upper Weardale (County Durham) I believe the ones frequenting our spruce woods are deterrimus, as they tend to be small and thin, scruffy looking, and very quickly blue-green staining (did I mention spruce?). So far in this dry summer not a single one has emerged, though.

Hello Jim,

to me it is this special colour, that separates it from C. deliciosus. It is more brownish, duller, the silvery shine is (nearly) missing - in total it ressembles much Lactarius quietus, hence the name quieticolor. Another difference is the milk change to darker red before becoming greenish, whereas in L. deliciosus it stays orange for a long time and does not darken before becoming greenish. Often one can see in L. quieticolor a blueish zone under the cuticule when you cut it, espcially in young fruitbodies. Those fruitbodies where called L. hemicyaneus by BON (I think it was BON). That blue zone is variable and often one finds collections where some fruitbodies show it and some do not. It never occurs in L. deliciosus, so IF you have it, it is a good additional character.
C. deliciosus f. rubescens is more similar to L. quieticolor, becuase in this forma the milk also darkens before greening. But I found this one only on calcareous soil in open places (e.g. Mesobrometum), whereas L. quieticolor is confined to sandy, acid soils. Also cap colour is typically +/- bright orange, as in typical L. deliciosus.

best regards,
Andreas
