Title: Contribution to the Domestication of Psathyrella candolleana
Author: V.J. Bella


Psathyrella candolleana is a species that is regularly encountered in Cameroon, especially in the rainforest zone. It grows on dung, soil, and dead and decaying wood. In Lekie Division, where this mushroom is very appreciated as it is in other regions of the country, it is called ‘Teamos’ in the local language, which means daily or regular, because local people think that when the fructification of this fungus occurs, the species grows every day during a relatively long time before ceasing. During this period of fructification, Psathyrella candolleana is harvested and consumed by indigenous people. Its stem and cap are very tender, sweet and easy to cook.

It is true to say that this species as well as many of this genus is very small compared with many large basidiomycetes: the cap size is rather small (1–5 cm of diameter).

Our objective was to make available simple cultivation methods for this mushroom, which is why we adopted interviewing as the main means of data collection.

Cultivation, as for the most of the saprophytic fungi, includes three main stages. The first stage consists of the preparation of the inoculum from the spores or by vegetative means. The substrate used is potato dextrose agar. After about 7 days, this stage provides a good inoculum. The second stage consists in having mycelium; that is, seed available to inoculate maize raw materials. This stage takes about 10 days. The third stage consists of producing edible mushrooms on maize raw materials. It can be also called the production of carpophores stage. This third stage is as long as the second one.
Psathyrella candolleana grows over a period long as 1 month under the conditions easily achievable by a large part of the poor population. The technology used is simple and the product is appreciated by the indigenous people. Its cultivation should help both developing country governments and populations as it presents advantages.
