It was presumed to be a mold of the genus Cladosporium.

　The genus Cladosporium is a common mold that floats in the sky and inhabits the stalks and leaves of plants that have just died in nature, and quickly uses nutrients that are easy to use before other molds grow up, produce and scatter large quantities of abundances, and move to new habitats. In addition, although this mold has a high separation rate from house dust, it cannot be grown in this, it seems that it grows in walls, ceilings, kitchens, washrooms and bathrooms, and is supplied to house dust.
