Significance We present the genomes of five new bonnet mushroom Mycena species, formerly last fungal bioluminescent lineage lacking reference genomes. These genome-scale datasets allowed us to construct an evolutionary model pinpointing all possible changes in luciferase cluster across fungi and additional genes involved bioluminescence. show that clusters were differentially lost different lineages particular a substantial loss was observed mycenoid lineage. This can be attributed genome regions underwent dynamics. Our findings offer insights into evolution how gene emerged 160 million years ago frequently or maintained due differences plasticity.
