Abstract:

Clitocybe tabescens root rot of sand pine in Georgia and Florida has caused up to 25 percent mortality in some Ocala race plantations. Advanced symptoms in crowns of slowly dying trees are thin chlorotic foliage and reduced shoot growth, but rapidly killed trees have wilted foliage which eventually turns dark, reddish-brown. Mycelial mats of C. tabescens with small perforations are found in the cambial region of infected roots and root collars of most diseased trees. Rhizomorphs of C. tabescens were not found in the field but do form readily in culture.
