Mixed-reproductive strategies, competitive mating-type distribution and life cycle of fourteen black morel species

Abstract Morchella species are well known world-round as popular and prized edible fungi due to their unique culinary flavor. Recently, several species have been successfully cultivated in China. However, their reproductive modes are still unknown, and their basic biology needs to be elucidated. Her...
