The intersterility groups Pleurotus djamor, P. pulmonarius, P. ostreatus were
identified in a Mexican wild strain collection through crossing the strains with reference
monosporics and dikarion – monokarion. Due to lack of reference strains or the similarity
between compatibility alleles, P. levis, P. agaves and P. smithii were identified by phylogenetic
analysis of ribosomal DNA ITS1-5.8S-ITS2 region sequences. The strains were cultivated
on coffee pulp in order to evaluate its productivity and describe the variety in form, size,
color, texture and flavor of the fresh basidiomes. In relation to productivity it was found six
strains of P. djamor with early fructification (12 days) and five with outstanding productivity
(116-178% of Biological Efficiency). One strain of P. pulmonarius showed a continued
productivity (non intermittent) and other two with excellent productivity (110-140% of
BE). The P. smithii and P. agaves strains did not show fructification to 26ºC.
