Peach scab, also known as peach freckles, [1] is a disease of stone fruits caused by the fungi Cladosporium carpophilum. [2] The disease is most prevalent in wet and warm areas especially southern part of the U.S. as the fungi require rain and wind for dispersal. [3]
Citrus Black Spot has a large economic impact on many countries because the black blemishes make it undesirable for human consumption and therefore the infected fruit cannot be sold. This type of economic impact is felt most in Australia and South Africa where the disease has been present for a number of years. [37]
The clinical presentation is typically single or multiple patches of hair loss, sometimes with a 'black dot' pattern (often with broken-off hairs), that may be accompanied by inflammation, scaling, pustules, and itching. Uncommon in adults, tinea capitis is predominantly seen in pre-pubertal children, more often boys than girls.

The pathogen can infect both green and ripe fruit; spots are not evident on green right away, but over time they develop. [5] Symptoms are most common on the fruit, but they may also appear on the stem, leaves, and roots. [2] In potato, C. coccodes is characterized by silvery lesions on the tuber surface which result in a deterioration in skin ...
Dermatophyte (from Greek δέρμα derma "skin" (GEN δέρματος dermatos) and φυτόν phyton "plant") [1] is a common label for a group of fungus of Arthrodermataceae that commonly causes skin disease in animals and humans. [2] Traditionally, these anamorphic (asexual or imperfect fungi) mold genera are: Microsporum, Epidermophyton ...
They are supported by the vegetative mycelium containing uni– (or mono–) nucleate hyphae, which are sterile. The mycelium containing both sterile and fertile hyphae may grow into fruiting body, the ascocarp, which may contain millions of fertile hyphae. An ascocarp is the fruiting body of the sexual phase in Ascomycota.
The mycelium then cover this necrotic area. Once the xylem is affected, other symptoms occur higher up in the plant. These can include chlorosis, wilting, leaf drop, and death quickly follows. On fruits, the initial dark lesions occur on the tissue that comes in contact with the soil. Next, white fungal mycelium covers the fruit and it decays.
