Elymus and Macropidia, are which type of mutual multicellular organisms?
Macropidia Macropidia fuliginosa, the sole species of genus Macropidia, is a perennial rhizomatous flowering plant. Commonly known as the black kangaroo paw, it is endemic to Southwest Australia, specifically from Perth to Geraldton in the north of the region.
Multifurca Multifurca is a rare genus of ectomycorrhizal fungi in the family Russulaceae. It was described in 2008, after molecular phylogenetic study had shown that it forms a monophyletic lineage within the family, sister to "Lactarius". The genus contains six species known from the United States, Mexico, Costa Rica, India, China, Thailand, Australia, and New Caledonia, but so far has not been reported from Europe, Africa, or South America. Four of those species were formerly classified as "Russula" section "Ochricompactae", and "Multifurca furcata" was originally described as a "Lactarius" species.
