In Ascomycetes: 1.The asexual spores are conidia produced endogenously on the special mycelium called conidiophores. 2. Conidia on germination produce mycelium. 3. Sexual spores are called ascospores which are produced exogenously in sac like asci 4. These asci are arranged in different types of fruiting bodies called ascocarps.

hey!!

here ur answer!
______________
Reproduction in Fungi
Vegetative propagation: By Fragmentation, Fission & Budding.
Asexual reproduction: By spores called conidia or sporangiospores or zoospores.
Sexual reproduction:-By oospores, ascospores and basidiospores. They are produced in distinct.
structures called fruiting bodies.
The sexual cycle involves 3 steps:
a. Plasmogamy: Fusion of protoplasm between two motile or non-motile gametes.
b. Karyogamy: Fusion of two nuclei.
c. Meiosis in zygote resulting in haploid spores.
When a fungus reproduces sexually, two haploid hyphae of compatible mating types come together
and fuse.
In some fungi the fusion of two haploid cells immediately results in diploid cells (2n)
In other fungi (ascomycetes and basidiomycetes), a dikaryotic stage or dikaryophase (n + n i.e. two
nuclei per cell) occurs.
Such a condition is called a dikaryon. Later, parental nuclei fuse and the cells become diploid.
The fungi form fruiting bodies in which reduction division occurs, leading to formation of haploid
spores.

____
↪It is the largest phylum of Fungi with over 64,000 species.
↪The defining feature of this fungal group is the meaning a microscopic sexual structure in which nonmotile spores called ascospores are formed.
