Mycorrhizae of Lactarius species can exude drops of latex, which flow out of the laticifers after injurance of turgescent mantles. Latex drops can have typical colours. In addition, some species of ectomycorrhizae are known, which do not belong to the genus Lactarius, e.g. Piceirhiza oleiferans, which can also exude milky droplets after injurance, but those are consistently white, and are not formed within laticifers. They occur as dense oil drops in many of the mantle cells.
