There are several species parasitic on plants causing leaf spots. Examine cultures of Ascochyta and mount a portion of colony in water. Look for the characteristic conidia. In the Hyphomycetes the mycelium is well-developed and budding cells are absent. The conidia are borne on conidiophores which are not in a fruting body.
Some species form only sclerotia.
The form-order Moniliales is a very large group consisting of important species that are plant pathogens, human pathogens and fungi which are widely used in various industry. We will consider four form-families in this exercise. Two important form- genera are Aspergillus and Penicillium which we will consider in the next exercise. Geotrichum - The hyaline mycelium in Geotrichum fragments into arthrospores with truncate ends. Mount a small portion of a colony in water and observe fragmenting hyphae and arthrospores.
