Summary Trait spectra have been used in various branches of ecology to explain and predict patterns species distributions. Several categorical continuous traits proposed as relevant for ectomycorrhizal fungi, but a spectrum that unifies co‐varying remains be established tested. Here, we propose nitrogen acquisition carbon use trait fungi nitrogen‐limited forests, which encompasses several morphological, physiological, metabolic traits. Using simple stoichiometric model, the is linked concept apparent efficiency resolves contradiction with high supply host can maintain transfer despite building large mycelial biomass. We suggest fungal are distributed along this spectrum, lifestyles ranging from ‘absorbers’ niche productive forests availability soluble ‘miners’ ability exploit organic matter low availability. Further, ways test outlined empirically.
