- In macrocyclic and demicyclic life cycles, the rust may be either host alternating ( heteroecious ), i . e ., the aecial state is on one kind of plant but the telial state on a different and unrelated plant, or non-host alternating ( autoecious ), i . e ., the aecial and telial states on the same kind of plant . "'Heteroecious "'rust fungi require two unrelated hosts to complete their life cycle, with the primary host being infected by aeciospores and the alternate host being infected with basidiospores.
