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.
Termitomyces Termitomyces is a genus of basidiomycete fungi belonging to the family Lyophyllaceae. There are about 30 species in the genus. They are the food source for a subfamily of termites, the Macrotermitinae, who enjoy an obligate symbiosis with the genus similar to that between "Atta" ants and "Attamyces" mushrooms. Despite this relationship, spore transfer is still accomplished mainly by shedding from mushrooms, which protrude from the termite mounds.
