Biotechnology of morel mushrooms: successful fruiting body formation and development in a soilless system
- 1.3k Downloads
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 Morchellarufobrunnea 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.
