Mycology Proficiency Testing Program (PTP)

PT Mold Master List Instructions

The master list is intended to guide participating laboratories on the scope of Mycology (GENERAL) Proficiency Testing Program. This list is meant to illustrate acceptable identification and the test grading policies. It does not include every mold that you may encounter in your laboratory. These guidelines supercede any previous instructions for reporting molds.

A complete answer will include name of the genus and species, when both genus and species are listed e.g. Microsporum nanum, or Sporothrix schenckii. Any answer that shows "sp." is not acceptable.

It is not necessary to speciate members of the genus listed as Rhizopus sp. If you speciate such an organism and the species is wrong, the grade will reflect consensus answers of the referee and/or participating laboratories.

If a genus includes both specific species and the epithet "sp." e.g. Aspergillus fumigatus, Aspergillus niger, the members of the genus that must be speciated as indicated. Other members of the genus may either be identified to species or just as "sp."

You may add the words "group" or "complex" to an organism if appropriate [e.g. Aspergillus flavus group.]
