Lactarius omphaliformis

Lactarius omphaliformis Romagn. (illustrated 100% life size) Very similar to L. obscuratus, with a larger and brighter cap. Cap 13–17mm across, or even reaching 35mm, centre often wrinkled and lumpy; tawny to russet or cinnamon, without olive tinges, sometimes with darker centre. Stem 16–40×2–4mm; pale tawny. Flesh pallid; very thin in the cap. Gills more distinctly decurrent and thicker, well spaced. Milk white. Spores 6.5–7.5×5.2–6.5¼; ornamented like L. obscuratus. Habitat with alder and birch; late summer to autumn. Very rare. Not edible. Note in my first book I published this under the name Lactarius cyathula (Fr.) Fr. as per the New Check List (1960), but this name is now considered to be a nomen confusem.
