In North America, some\n Imaia<\/jats:italic>\n ,\n Kalapuya<\/jats:italic>\n , and\n Leucangium<\/jats:italic>\n species are highly regarded gourmet edible fungi. In this study, we address longstanding questions about the\n evolution, systematics, and trophic mode of these fungal genera. We used high-throughput sequencing and a custom genome assembly pipeline to sequence and assemble 41 new genomes of epigeous and hypogeous\n Morchellaceae<\/jats:italic>\n genera and outgroup taxa from the sister family\n Discinaceae<\/jats:italic>\n .\n Phylogenomic reconstructions based on high-quality\n de novo<\/jats:italic>\n genomes and published reference genomes support a single transition from epigeous to hypogeous habit within the\n Morchellaceae<\/jats:italic>\n . These results are corroborated by phylogenetic evidence from LSU,\n tef1<\/jats:italic>\n , and\n rpb<\/jats:italic>\n 2 with a larger dataset of specimens and publicly available sequences. We also provide direct morphological and molecular evidence that one species of\n Leucangium<\/jats:italic>\n from North America forms ectomycorrhizas on\n Pseudotsuga menziesii<\/jats:italic>\n in a natural habitat. Stable\n Morchellaceae<\/jats:italic>\n also obtain carbon via ectomycorrhizal symbiosis. Phylogenetic and morphological analysis supports the description of two new species and one new combination of\n Leucangium<\/jats:italic>\n as well as one new species and one new combination of\n Imaia<\/jats:italic>\n from North America. We also discuss additional,\n undescribed diversity detected in our phylogenetic analyses of these genera derived from fungarium specimens, mycophagous mammal scat samples, and other environmental samples.\n
