Abstract

Morchella spp. ascocarps (morels) are some of the world’s most sought-after mushrooms. Successful cultivation of morels is still a rare and difficult task despite over 100 years of effort. Here we provide the first report of successful Morchella rufobrunnea fruiting body initiation and development in laboratory-scale experiments. Mushroom initials appeared 2 to 4 weeks after first watering of pre-grown sclerotia incubated at 16 to 22°C and 90% humidity. Mature fruiting bodies reached 7 to 15 cm in length and were obtained after the five morphological developmental stages of this Morchella species: sclerotium formation, scelerotium germination, asexual spore formation, formation of initial knots and development of the fruiting body.

Purpose of the work The purpose of this work was to study the option of cultivating the saprophytic species Morchella rufobrunnea in a soilless system and its different developmental stages during the process.
