This is a very rare agaric originally thought to be Lactarius furcatus described by Coker from North Carolina, USA. In Hesler and Smith's (1979) treatment of Lactarius for North America, Coker's type is the only specimen cited. The glaucescent, white, acrid latex, forking lamellae, and zonate pileus appear as distinctive features. The zonations from the pileus surface also appear in the pileus context. This taxon is another example of the North Temperate heritage of mycorrhizal agarics in neotropical oak forests.

B. Buyck et al. (Fungal Diversity 28: 15-40. 2008) has shown that this species, and four others, belong in the genus, Multifurca. Wang et al. in 2018 (PlosOne) describe additonal species from a global view and discuss the phylogeny and biogeography of Multifurca.
