Major research emphasis has been on the classification, systematics, biogeography,
and diversity of mushrooms. Mushrooms are important in the world's ecosystems
as primary decomposers, litter binders, and nutrient recyclers. In addition, they
form obligate and essential symbioses with forest trees. Up to the present time,
my studies on mushrooms have required field work in northern and southern temperate
zones of the Americas and Europe, as well as Australia, Argentina, Bolivia, Chile,
Colombia, Costa Rica, Dominican
Republic, Ecuador, Indonesia, New Zealand, Papua New Guinea, Puerto Rico, and
Venezuela. Continuing field efforts in these areas will add substantially to general
investigations on tropical and temperate fungi.
My field work is coupled with a critical laboratory analysis that includes
microscopical examinations as well as molecular analysis. During the past
two decades, field and laboratory research has focussed on tropical and
temperate South America. Currently, I am emphasizing studies on the taxonomy,
phylogeny, mycorrhizal relationships, and biogeography of the Boletaceae
(Porcini mushrooms). International collaboration with other specialists
is underway to catalog fungal
diversity in Central America. Such an inventory will add substantially
to our knowledge of the saprobic and mycorrhizal mushrooms beneficial to
Central and South American oak
and alder forests.
