1Production was scored after 4 wk of cultivation on MEA, CYA, CZA and CY20S; the ratio shows the number of strains producing and not producing pigment/sclerotia; media on which pigment or slerotia were produced, are listed in the parentheses and sorted by frequency. See section Taxonomy for more details concerning colours of soluble pigments and sclerotia, and strain numbers.
