Perilla frutescens seed agar, a new medium for identification of the Cryptococcus species complex: evaluation for all major molecular types.

Here we present a new and simple medium made by Perilla frutescens seed as a tool for identification of the Cryptococcus species complex, namely Cryptococcus neoformans and Cryptococcus gattii. Its usefulness was evaluated for all major molecular types within the Cryptococcus species complex. As a result, this medium is better for identification of the species complex compared with Guizotia abyssinica or Helianthus annuus seed medium.
