What is the function of macroconidia?
These asexual spores play important roles in the disease cycle: macroconidia and microconidia are produced on the stem surfaces of infected plants and serve as secondary inocula to spread the fungus to neighboring host plants, and chlamydospores are endurance organs in soil and act as primary inocula when suitable host …
What is ectothrix and Endothrix?
Endothrix refers to dermatophyte infections of the hair that invade the hair shaft and internalize into the hair cell. This is in contrast to exothrix (ectothrix), where a dermatophyte infection remains confined to the hair surface.

Which fungus produces macro and Microconidia?
The filamentous fungus Fusarium oxysporum is a soil-borne facultative parasite that causes economically important losses in a wide variety of crops. F. oxysporum exhibits filamentous growth on agar media and undergoes asexual development producing three kinds of spores: microconidia, macroconidia, and chlamydospores.
What is Annelloconidia?
annelloconidia) A conidium produced by an annellide. Apophysis. A swelling. The term is primarily applied to the funnel-shaped swelling of a sporangiophore, immediately below the columella, seen in some zygomycetes.
What causes endothrix?
tonsurans causes endothrix hair invasion often referred to as “black-dot” because hairs break off close to the surface. Kerion is an inflammatory pustular folliculitis involving circumscribed scalp areas, most commonly caused by T. verrucosum.
Does fungus cause hair loss?
However, when the infection is severe the fungus weakens the hair fiber, making it easy to break off. This can result in a patchy, diffuse hair loss. Treatment generally involves shaving off affected areas.
