Lactarius acerrimus Britzelm. |
The cap is orange-buff to ochre-pink, convex-flattened, then depressed, irregular; its margin is smooth to wavy, irregular, inrolled for a long time. The cap surface is generally with faint ochre-orange concentric bands near the margin, finely downy in the youth, then smooth, viscid in damp weather. The stem is frequently eccentric, short and almost full, creamy-white to buff, sometimes with brown blotches, without ring. The flesh is firm, white, unchanging; its taste is very hot; the odour is faint and pleasant, fruity, of apple or overripe pears; its texture is grainy (breaking like a chalk stick), exuding when cut a milk white and unchanging. The gills are pink cream then pale ochre, broadly adnate to decurrent, not very crowded, typically wrinkled, forked and interconnected by ridges under the cap especially close to the stem (nb of gills per 90° ~ 28 ). The spore print is ochre-cream (D-E). This species is mycorrhizal. It grows on the ground, in broad-leaved woods, parks or grassy paths, ruts, on a rather calcareous and rich soil, most of the time with oaks. The fruiting period takes place from June to November.
Chemical tests : none. Distinctive features : cream to orange coloured cap, irregular, sometimes with concentric bands; creamy-pink gills, typically wrinkled and interveined close to stem; whitish stem, often eccentric; white and unchanging milk, very hot; fruity odour; with oaks Lactarius acerrimus is quite rare and localised in the forest of Rambouillet, and is infrequent, more generally speaking . | ||
