Different scenarios investigated, fossils used, ages for each fossil and distributions associated with the selected fossils.

Exponential distribution = Exp (offset, mean). The means were selected so that 97.5% of the prior probability for each fossil date would fall below the age of the major group the fossil belongs to, i.e. 400 Mya which is the age for the †Pezizomycotina crown and 650 Mya for the ‡ Ascomycota base, both according to [32] and 160 Mya which is the age of the * Lecanorales based on [59].

指数分布（Exponential distribution）采用Exp（偏移参数，均值）的形式。我们选取均值参数，使得每个化石定年的先验概率有97.5%落在该化石所属类群的分化年龄之下，具体为：400百万年前（million years ago，缩写Mya）对应†盘菌亚门（Pezizomycotina）冠群的分化年龄，650 Mya对应‡子囊菌门（Ascomycota）基部的分化年龄，上述两类群的年龄数据均引自文献[32]；而基于文献[59]的*茶渍目（Lecanorales）的分化年龄为160 Mya。
