Trends in strain Tmax over time. (A) Trend of fungal maximum temperature of growth Tmax during the last century, compared with the global temperature index. The fungal Tmax reported was calculated from a 10-year mobile mean. The temperature index is the global mean land-ocean temperature index, 1880 to present, with the base period 1951 to 1980. (B) Regression analysis of fungal Tmax and the global temperature index during the last 30 years.
