Figure S2. The distribution of isolations in the dataset by climate region. The number of unique isolations (upper, bold) and the number of unique OTUs (lower, italics) are shown. Climate regions correspond to the 9 climatically consistent regions of the contiguous US identified by NOAA (https://www.ncdc.noaa.gov/monitoring-references/maps/us-climate-regions.php). We included the additional category of Arctic for Alaskan samples.

Figure S4. Taxonomic representation across unique isolations (light grey, top count) and unique OTUs (dark grey, bottom count). The dearth of Pezizomycotina OTUs is likely reflective of our isolation protocol, in which the selection of mold-like colonies was deliberately avoided.

Figure S7. Cosmopolitan OTUs were defined as those OTUs that were isolated from regions where they were expected based on sampling density (allowing for one missed region). Twelve cosmopolitan OTUs were identified using this approach. A) Cosmopolitan yeasts were enriched in soil samples (p= 0.003). B) Cosmopolitan yeasts all belong to Saccharomycotina or Basidiomycota, but there was no enrichment for taxonomic groups among cosmopolitan OTUs. C) Map of cosmopolitan isolation locations. OTUs are differentiated by color.

Figure S8. Forty discrete substrate categories were annotated for 1,520 isolations. A) Distribution of unique isolations among substrate categories. Category sampling was uneven. B) Substrate genera could be assigned to 1,061 isolations of diverse substrate categories. For each genus, the type of substrate collected is shown with different color bars. Substrate categories were either directly harvested from the substrate (e.g. pine needles from pine trees) or indirectly associated with the substrate (e.g. soil from the base of a pine tree).
