Abstract

This paper is part of a wider work on tropical wood-decaying fungi from Los Tuxtlas
Tropical Biology Reserve in Veracruz, Mexico. Malt agar-sawdust-guaiacol and Badcocks's
sawdust methods were used to assay isolates obtained from basidiomata collected on
angiosperm wood substrates. In the first method 14 fungi gave positive withe-rot reaction. In
the second one, 7 fungi grew and showed white-rot reaction on pine sawdust, and the
remainder 8 had growth problems on it but grew densely and yielded white-rot reaction on
sweetgum sawdust. Previous and present results suggest that a substrate selectivity trait might
be involved in some strains. Rot-type importance in taxonomy, phylogeny and biogeography
are discussed.
