In this study, we examined the nature of latex in Lactarius Pers. 1797 spp. to clarify the role on fungivorous predation. In the field, we compared the degree of predation on taxonomically closely related latex-exuding Lactarius spp. and latex-non-exuding Russula Pers. 1796 spp. (Russulaceae) at developmental stages of sporocarps. We clarified that Russula spp. suffered more infestation than did Lactarius spp. at young and mature developmental stages, whereas Lactarius spp. did only at decaying stages. We measured the amount of latex exuded varied according to developmental stage and sporocarps parts in Lactarius spp.: mature sporocarps exuded more latex than did younger ones, while decaying sporocarps exuded the least, and the same patterns were observed at sporocarps parts: the amount of latex was more intense at hymenophore and cap than at stripe. At feeding experiments, three-band garden slugs Ambigolimax valentianus F´erussac, 1822 avoided feeding on sporophores of Lactarius spp. when they exuded latex, but fed on them when they did not. Our observations suggest that fungivores generally escape higher density of the latex at feeding using signs volatized by sporophores with exuding latex.}, pages = {1--10}, title = {Fungal defense against mycophagy in milk caps}, volume = {60}, year = {2016} }
