There is no answer as to why they are produced-they just help in spreading infection to new emerging leaves, older susceptible leaves, or to the soil surface.
Their production is as follows:
Once the fungus has obtained adequate food reserves from the colonized fern leaves, asexual reproduction follows. A profusion of tiny spores are produced in acervuli (spore production structures) that form on disease-damaged leaf tissue about 4 to 6 days after infection. Spores are dispersed primarily by water to other susceptible leaves and the disease cycle is repeated.
Sporangiospores- asexual spores produced at the end of aerial hyphae enclosed within a sac. Rhizopus makes these types of spores.Conidiospores- asexual spores produced in chains at the end of aerial hyphae and are not enclosed by a sac. Penicillium makes these types of spores.
The ability to undergo meiosis and produce genetic variation does not apply equally well to both sexual and asexual spores. Sexual spores are formed through meiosis, which shuffles genetic material and leads to genetic variation. Asexual spores, on the other hand, are produced by mitosis and do not contribute to genetic diversity.
sexual spores and asexual spores
During asexual reproduction, ascomycotes produce a different spore called a conidia.
They can be present.
Profusion
Spores can be both asexual or sexual. It depends on the fungus. Some fungi even produce both kinds of spores.
They are classified by their mode of development.Sporangiospores- asexual spores produced at the end of aerial hyphae enclosed within a sac. Rhizopus makes these types of spores.Conidiospores- asexual spores produced in chains at the end of aerial hyphae and are not enclosed by a sac. Penicillium makes these types of spores.Read more: What_are_the_two_types_of_asexual_spores_of_mold

Spores are unnecessary to asexual reproduction.
Conidia are chains or clusters of asexual spores of ascomycetes develop from tips of conidiophores. Conidiophores is formed during asexual reproduction of ascomycetes, fungal hyphae grow form mycelium.
