Specimen notes
Public Note:
dark green hsl(168, 22%, 41%) with lilac elements to centre. Taste mild. FeSO4 immediately pink on stem. SV flushing pink then rapidly grey fading. Gills D-F. Cap with fusiform and cylindrical septate dermatocystidia (none clavate) with grey/violet granular contents in SV. Mature spores with connectives in lines forming a reticulum (E). Keys to aeruginea. R. pseudoaeruginea and R. langei are known from Europe with Q. cerris. To , PL:"Extremely difficult. It does not key out satisfactorily in Sarnari. I have also tried Funga Nordica, but no joy there either. A search for Russulas under Turkey oak yielded :R dryophila, but it is not this species, and R. lividopallescens which is possible but the spore ornamentation has elongated warts, which your specimen does not have. In Romagnesi you get in to the Griseinae, a notoriously difficult group. It keys to R. grisea and most of the description looks OK but I cannot see the bifurcating hyphae in the stipe despite cutting several sections. You will need to look at the pp under your microscope and see whether you can see the structures illustrated on page 291 of Sarnari. If it is R. grisea, then this is reported with oaks including holm oak in the Mediterranean, but I can find no record with Turkey Oak". SV-ve when checked again? Stem with cystidia like cap. Spores length=6.5–7.3µm (µ=7.0, σ=0.28), width=5.3–6.0µm (µ=5.7, σ=0.21), Q=1.1–1.4µm (µ=1.24, σ=0.07), n=16
