I felt that some, among the list members, might be interested in this---most informative treatise on fungi. Referring to the section on medical considerations might prove informative. The pictures are not for the faint-hearted. We are, at present, initiating a special study on bioremediation using lignin-based materials (sawdust, shredded tree refuse/heavy shrub trash, etc. as the substrate for the mycellium), for erosion control and soil stabilization. This investigation looks quite promising from both enviornmentally-friendly and cost-effectiveness considerations. Sincerely, Brooks Bradley.
