Notes

The effect of the enrichment of a humus by fungi on the dynamics of the Testate community has been observed on microcosm conditions. Four fungi have been tested; Fusarium oxysporum, Pythium sp., Stachybotrys atra and Humicola fusco-atra var. fusco-atra. The enrichment has been done by two techniques: I. Mixing fungi culture on vermiculite with humus in the beginning of the experiment. II. Repeated additions of liquid culture of fungi. The main result of this experiment is the important growth of Phryganella acropodia after addition of mycelium by the technique II. Hypothesis on the mycophagy of this species and its strategy are proposed. Other results are discussed as the stress induced by microcosm conditions or the antagonistic effect of the fungi, especially on Plagiopyxis declivis.
