Fungi: Ascomycetes

January 2012

The ascomycetes are a group of fungi that have septate hyphae. As a result of sexual reproduction they produce ascospores that are unique to that particular group. Most of the fungi within that group produce asexual spores called conidia that we use to identify the organisms.
