The Research and Conservation Department announces the establishment of the Sam Mitchel Endowment for mycological research. Dr. D.H. 'Sam' Mitchel, a very dedicated volunteer and mycologist, had the vision to establish a collection of Colorado mushroom specimens here at Denver Botanic Gardens. In Oct. 2009 we celebrated the memory of this remarkable man by officially naming The Sam Mitchel Herbarium of Fungi.
