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.
