can cause tinea cruris

superficial class

what type of fungi is this?

Answer 10

dermatophytes

Question 11

spores outside the hair shaft

Answer 11

Ectothrix

Question 12

spores inside of hair shaft

Endothrix

Question 13

characterized by the occurrence of dense
masses of fungal mycelia and epithelial debris which
form yellowish, cup-shaped crusts called “scutula.”
