Eurotiales (antagonists)

This order of ascomycetes contains around 1,000 species of saprophytic and plant pathogenic molds. Penicillium and Aspergillus are familiar members of this group. However, several species or strains are recognized as beneficial antagonists to plant diseases. This page deals with the latter group.

Sexual fruiting bodies (typically cleistothecia) are often rare. There are of variable size, from large forms like in truffels to microscopic structures. The cleistothecia are closed and contain round asci. The asexual conidia are typically spherical and are produced in chains. In the common molds, the conidiophore has a terminal, swollen "vesicle" from which the elongated, conidia-forming "phialides" originate, sometimes with a layer of intermediate cells.

Note:
This page deals only with species which are antagonistic to plant diseases, for other groups see


The following genera of antagonists are currently entered in the system:
