 The flesh is <unk> to bluish in color , slowly turning greenish after being exposed to air ; its taste is mild to slightly acrid . The flesh of the entire mushroom is brittle , and the stem , if bent sufficiently , will snap open cleanly . The latex <unk> from injured tissue is indigo blue , and stains the wounded tissue greenish ; like the flesh , the latex has a mild taste . Lactarius indigo is noted for not producing as much latex as other Lactarius species , and older specimens in particular may be too dried out to produce any latex .
