Differences in sexual life history traits between ectomycorrhizal and saprotrophic fungi and ecological consequences. Species have evolved complex traits that form reproductive syndromes according to their life style and environment. We expected the reproductive syndromes of mutualistic ectomycorrhizal fungi to differ from those of saprotrophic fungi since their strategies of resource acquisition considerably differ. The mutualists receive resources from the host, which might provide degrees of freedom in the development of reproductive traits such as fruiting body size. We used data from fungi collected in three consecutive years (> 200,000 fruiting bodies) as well as from the literature. We found clear evidence that evolving to a mutualist leads to larger fruiting bodies. We found a trade-off between fruiting body size and the number of fruiting bodies only for saprotrophic fungi. We provided insights that cross-species differences between the guilds translates into assemblages. Furthermore, the fruit body size was correlated to the occurrence of ectomycorrhizal and saprotrophic fungi along environmental gradients, but not always in a similar way. Overall, we found clear differences in the assemblages of ectomycorrhizal and saprotrophic fungi along environmental gradients, and these differences can be predicted from their strategies of resource acquisition.
