Comments: Experts are able to resolve two varieties of this species: Lactarius blennius var. blennius and Lactarius blennius var. fluens. I was unable to assign this find to one of them. Following the key of Section 6 of Lactarius (Ref.: 2, p383) this find should be Lactarius blennius var. blennius based on piled dimension (3 – 7 cm for var. blennius contrary to 5 – 12 cm for var. fluens) or Lactarius blennius var. fluens based on strong production of milk (even in quite dry state!). Also variable hut color speaks for this variety. On the other hand, the absence of lighter, almost whitish hut edge speaks in favor of the first option. The only reliable microscopic trait (Ref.:8) – thickness of ixocutis – has not be used because of quite dry fruitbodies. Also, if one reads the description of both varieties in Ref. 9 the text is almost identical and the associated drawings definitely are such. Too hard a problem for me.
Description of the find: six or seven pilei present in an area of about 4 × 3 m; pilei diameter 4.5 – 7 cm, surface almost dry, only slightly sticky (found after a long period of dry weather) but leaf debris firmly stuck to the hut surface speaking in favor of presence of a distinctive ixocutis; trama and gills of about the same thickness; milk instant, abundant, white, after a longer time, when almost dry, it becomes greenish-gray; gills bruise slowly and mildly darken to brownish, otherwise the fruitbodies do not discolor when handled; stipe 3.5 – 4.6 cm long, 9 to 12 mm in diameter; only minutely sticky; SP abundant, light beige with slight yellow tint, oac851.
