The invention pertains to culturing ascocarps or fruitbodies of species of the genus Morchella. Mycelia are provided nutrients and subsequently produce sclerotia. Sclerotia store sufficient nutrient to supply the ascocarps that are developed later. The mycelia and attendant sclerotia are established in a nutrient poor substratum. The fungus is induced to give rise to ascocarp development by initially maintaining the fungus in an environment that is poor in exogenous nutrients, and by exposing the fungus to a high level of water. After induction, primordia appear. The period from primordia appearance until midway to maturation of the fruitbodies represents a critical period during which the fruitbodies are prone to abort. During this critical period, particular attention is directed to maintaining favorable conditions. The fruitbodies, which may be grown to maturation, are harvested. |
