Mount some sporangia and sporangiophores and note their characteristics as stated above and in the key. This family contains the single species, Syncephalastrum recemosum , a heterothallic inhabitant of soil and dung and of worldwide distribution. The merosporangia of this genus are borne on swollen tips of sporangiospores. Observe cultures under the dissecting scope and make a mount of the sporangiospores and observe merosporangia under the microscope. This is a small order of mycelial fungi that parasitize animals such as insects, or they occur saprobically in soil or on dung.
Asexual reproduction is often with spores that are forcibly discharged.
There is one family, the Entomophthoraceae. In Entomophthora , the spores are smooth, produced outside the host and forcibly discharged. Examine prepared slides of sections through an infected fly and observe the sporogenous cells and spores and their relation to the host.
