Palaearctic origin and repeated dispersal over the world shaped the biogeographic history of the saprophytic genus Coprinopsis (Psathyrellaceae, Basidiomycota)

Aim: The biogeographic history of most fungi is still poorly known, as well as the patterns and processes responsible for their diversification. Recent studies uncovered that most fungi have originated and present higher diversification rates in the temperate zone. The distributional pattern known for fungi is also different from many plants, animals and microbes. Using the most comprehensive phylogeny of the saprotrophic genus Coprinopsis, we aim to infer the biogeographic history and test evolutionary hypotheses in the genus.
Location: Worldwide
Taxon: Fungi, Basidiomycota, Psathyrellaceae, Coprinopsis
Methods: We used a four-gene alignment with 100 species to estimate divergence times using two fossil calibrations within Agaricales. The chronograms were used to estimate diversification rates and geographic state-dependent models were applied. We further reconstructed the ancestral range history of the genus.
Results: Molecular dating estimated that the genus has diverged ca. 41 Ma (E..., , , # Palaearctic origin and repeated dispersal over the world shaped the biogeographic history of the saprophytic genus Coprinopsis (Psathyrellaceae, Basidiomycota)

We include the materials used in the article, along with the images and tables containing taxonomic and geographic information utilized in the analyses.

## Description of the data and file structure

We provide Figures 1 and 2 in .tiff format containing the results of the biogeographical analyses and a .csv file with geographic data for the species. The geographic regions in this file are coded as \"0\" for Nearctic, \"1\" for Neotropical, \"2\" for Palaearctic, \"3\" for Afrotropical, \"4\" for Oriental, and \"5\" for Australian.

Additionally, a .doc file contains the supplementary information.
