thousands per cubic foot whereas the sclerotia of theYellow Morels are comparatively few in number. The differences between these two groups of Morels are soon seen after the clones or spores are put into culture.
Although Ron Ower (1986) was the first to note that Morels arise from sclerotia, the first to propose a complete Morel life cycle was Thomas Volk (1990), a rendition of which follows. Not fully illustrated in this life cycle is the asexual phase wherein sterile cells are borne on short hyphal branches, simil ir to cidia. An abundance of these asexual spores forms a powdery mildew, and has been called Costantinella cristata Matr. (Costantin (1936)).
