This is the tree we are looking for now on the hunt for Morels. One reason is because it is a primary host for Morels (with particularly good fruiting under recently dead trees), and additionally because it indicates the appropriate habitat. Here it is seen by the river, which is typical habitat and a great place to find Morels. This is a great tree, though another example of man-made tragedy as the introduced Dutch Elm Disease has taken down a number of specimens and generally prevents these Elms from reaching their full age potential.
