Answer:-
ASCOMYCETES:
Common name- Sac fungi.
Mycellium- Septate, branched.
Cell wall composition— Chitin.
Asexual spore- Conidia.
Sexual reproduction— Gametangial contact, Gametangial copulation, Spermatization, Somatogamy.
Fruiting body- Ascocrap.
Sexual spore- Dikaryon stage is found and distribution of dikaryon takes place by the help of crozier formation.
Examples- Peziza, Claviceps, Penicillium.
DEUTEROMYCETES:
Common name- Fungi Imperpecti.
Mycellium- Septate and branched.
Asexual reproduction— through conidia.
They can be saprotrophs, parasites and mainly decomposers.
Cell wall- Chitin.
Perfect stage or Sexual stage absent.
Examples— Alternaria ( Early blight of potato ), Colletorichum, Trichoderma.

Ascomycetes and Deuteromycetes
Septate
Having cross walls in a hypha or spore. A cross wall is called a septum.
Germ tube
The early growth of of a hypha produced by a germinating fungus spore.
Apressorium
The swollen tip of a hypha or germ tube that facilitates attachment and penetration of the host by a fungus.
Haustorium
A specialized fungal hyphae that enters and absorbs nutrients from a host cell.
Ascomycetes
Fungi in the Phylum Ascomycota that produce sexual spores in sac-like structures called asci.
Deuteromycetes
A group of fungi with no known sexual stage. Often, when a sexual stage is discovered, these fungi turn out to be Ascomycetes.
Anamorph
The imperfect or asexual stage of a fungus.
Teleomorph
The perfect or sexual stage of a fungus.
Conidia
Asexual, non-motile spores of fungi.
Conidiophore
A specialized hypha that produces conidia.
Ascocarp
Fruiting body of Ascomycetes that contain the asci and ascospores.
Asci
A sac-like structure that contains ascopores.
Ascospores
Sexual spores of Ascomycetes produced in an ascus.
Apothecia
An open cup-shaped ascocarp.
Perithecia
A flask-shaped ascocarp with an opening for releasing spores.
Cleistothecia
An ascocarp where the asci are completely enclosed.
Sporodochium
An asexual fruiting structure consisting of a cluster of conidiophores woven together on a mass of hyphae.
Pycnidium
A flask-shaped asexual fruiting body with an opening for releasing spores..
Acervulus
A subepidermal, saucer-shaped, asexual fruiting body producing conidia on short conidiophores.
Synnema
An asexual fruiting body consisting of fused conidiopores to form a stalk with conidia on the end.
Chlamydospores
A thick-walled asexual spore formed by the modification of a hyphal cell.
Sclerotia
Macroscopic mass of hyphae, usually rounded and darkened.
Septate
Having cross walls in a hypha or spore. A cross wall is called a septum.
