Monitoring of ecological restorations has rarely focused on fungi. In this study, we conduct a first‐ever monitoring of macrofungi in ecological restorations of coastal Indiana (U.S.A.) and present an approach and considerations that can be followed elsewhere. Forty‐two sites were surveyed over a 2‐year period for the presence of saprotrophic, mycorrhizal, and parasitic macrofungi. Sites included those considered to be restoration, prerestoration, or reference and were in wooded, semiwooded, or grassland habitats. With 1,103 observations, 277 species of fungi were identified. Most fungi were found in wooded habitats though some were in grassland restorations. Invasive plant cover negatively impacted fungal species richness. Monitored sites were compared to a set of reference sites using two different similarity indices (overlap and Jaccard), as well as the ratios of different fungal functional guilds, revealing that choice of index can impact how restorations are perceived to match targets. Last, we present a novel, tractable, and conservative way to assess and rank sites by the functional trait guilds of fungi. We show that such an approach can provide important additional information about the success of restorations such that functional guild ratios could be used as an indicator of restoration progress early‐on while functional values are better used in later phases.
