The traditional Lactarius subgenera Piperites, Plinthogalus (excluding the L. gerardii complex, which is in Lactifluus) and Russularia are in Lactarius as currently recognized. Lactarius acris is in subgenus Plinthogalus which falls out within the genus Lactarius. So assuming your collection is L. acris, it should be in Lactarius : ) Many of the well-known species such as L. deliciosus, L. torminosus, L. glyciosmus, L. controversus, L. lignyotus, L. romagnesii, L. rufus, L. tabidus, L. uvidus, etc. are still in Lactarius.

Other subgenera in Lactarius sensu lato, such as Lactifluus, Lactarius, Lactariopsis, etc. have been moved to the genus Lactifluus based on molecular evidence from a number of studies. Well-recognized species in these subgenera which are now in Lactifluus are L. volemus, L. vellereus and L. piperatus, etc. So, there have been some taxonomic shifts, however, the majority of well-recognized temperate, boreal and arctic-alpine species are still in the genus Lactarius. Not sure why Lactifluus acris was the only available name on MO.

Buyck et al. (2008) is a good read on this stuff and is publicly available:

The reference for the official proposal is also a good read for wrapping your head around the changes, but unfortunately it is not publicly available. I had to get it on inter library loan.
It is:

Buyck B, Hoffstetter V, Verbeken A, Walleyn R. 2010. Proposal to conserve Lactarius nom. cons. (Basidiomycota) with conserved type. Taxon 59(1): 295-296.

I wanted to call it Lactarius acris but this now seems to be Lactifluus acris which I for my part am not willing to accept. But nomenclature is once more against me as it seems.
