CULTURES
A Select Library of In Vitro Strains

The strains represented here are unique. Some are rare, not being available from culture libraries in North America, and potentially high yielding. We are constantly working with these strains, screening and maintaining cell lines. Fungi Perfecti is releasing the following strains for use on a conditional basis.

By purchasing these cultures, the customer agrees to the following terms. The purchaser is authorized by Fungi Perfecti to utilize our pure mushroom Spawn and Cultures for their own personal mycological experimentation, for the production of mushrooms for resale, and for the generation of additional mushroom spawn for the production of mushrooms for resale. The purchaser consents to use these strains for private use and not to generate spawn from them for resale or unauthorized distribution. Violators are subject to prosecution. The purchaser further agrees that mini-trials will be conducted prior to use in any commercial enterprise to assess their efficacy. The purchaser cannot and will not represent nor sell our strains in any form. Once shipped, Fungi Perfecti can not be responsible for the condition of any cultures. However, Fungi Perfecti will replace a culture if defective or should you lose it within one year of purchase at no additional charge.

Each strain is designated with the Stamets "P-value" scale, signifying the expansion of mycelium covering a 100 x 15mm petri dish (approximately 1,000–2,000 cell divisions). The first time a wild species is tissue cultured, the age is denoted as P-O. Thereafter each successive growth over the petri dish's surface is described in increments of P-l, etc. This library tries to maintain strains closest to their wild origins or closest to their peak fruiting potentials. Each culture comes in a 125 x 20mm glass test tube.

When you place an order for Fungi Perfecti's Pure Mushroom Cultures, you will be required to read and acknowledge a Sale Agreement prior to delivery. The text for this agreement is available for viewing online:
