Observation 165340: Morchella diminutiva M.Kuo, Dewsbury, Moncalvo & S.L.Stephenson
When: 2014-05-15
No herbarium specimen

Notes: Very few of these small “deliciosa” forest morels here in the upper mid-Atlantic/lower northeast this year. Very slow warmup compounded by a torrential rain event in early May is my best explanation. Morels like this type, which appear in forests of living trees, seem to be much more finicky than the dead elm/dying apple types. I think the production of morel mushrooms as a reaction to fungal nutrient deprivation needs to be well timed for these healthy forest types. That is, the increase in soil temperature must coincide with the leafing of the trees. For the morels that occur with apple/elm, the response to loss of host tree need not be specially timed.
