Anyone know WHY under dead elms? Would they grow around the stump of a dead elm that was cut down?
Why dead elms?
The following is a brief summary that could possible satisfy your question. Please keep in mind, while morels have been grown successfully commercially, there is much more to this little fungus than the scientific community of today has yet to unlock. Commercially grown morels carry a 1/10th of the flavor of mother natures.
Morels are fungus. Morel mycelium lives a fruitful life on the root system of an elm tree amongst a host of other nutrient laced underground locations. When the elm tree is overtaken by dutch elm disease & begins to die, the nutrient supply begins to slowly diminish as well. As a result, the mycelium begins to form what is termed in the scientific community as sclerotia. Sclerotia can best be thought of as the root system of an actual morel mushroom. Reproduction is mother natures only true survival mechanism. If local conditions remain favorable in the spring of the year, sclerotia will develop a morel mushroom which is the reproductive organ of the fungus. Once mature, the morel will spore out, releasing hundreds of thousands of little “seeds” into the air. Wind, rain, insects, animals & humans, all serve well as hosts spreading the spores throughout the forest. Once reintroduced to the soil, if the correct nutrients are present and conditions are favorable, the morel mycelium will begin the life cycle again. Favorable environmental conditions in conjunction with different nutrient combination’s are the keys that the scientific community has yet to completely unlock.
On line source for a more in depth look at the life cycle of a morel. The author briefly mentions Michigan State University, but no mycologists from the University in this older article. One of the lead mycologist on the cultivation project at MSU was Larry Lonik. He’s the “old fart” 2nd from the right in this photo. He planned to hunt morels with us one afternoon on his way through SW Wisconsin from Magnolia, IL to a morel festival up in MN. He ended up staying three days & filming the lions share of his “Motherlode” video with us back in 2001. There was only one other man I consider more knowledgeable on morel mushrooms than Larry was. That was my father who taught me where, when, and how to hunt them as a strapping young lad. Larry just filled in some of the why’s.
