The most obvious difference is the color of the mold formations. Let’s observe the types of fungus, relying on it, as the simplest sign. Black  The most widespread and most dangerous of all types of mold. Usually appears in large numbers on walls and ceilings. At first glance, it seems that the spots are the same, but in fact they can belong to different groups. Of the variety of subspecies of this mold, aspergillus niger is considered the most common. It poses a particular danger to humans and animals, as it causes diseases consonant with the name – aspergillosis. Green Green mold (ascomycetes) spreads primarily in organic materials, soil or compost. However, they also do not disdain products, they can settle in vegetables as well. In appearance, these molds resemble deep green moss with an uneven surface. Green mold spreads quickly enough both in the contaminated product also in the human body, getting there with food. Pink It does not spoil the surface, like many other species, does not settle on the ceiling and walls, and does not even adduce a particular danger to humans (but it is still not recommended to eat food with it). It appears mainly on plant residues and rotten products (spoiled vegetables, fruits, in rare cases – cereals that have been wrongly stored). White White mold (mukor) almost always infects trees, houseplants and the soil in which they grow. White mold likes some products like cheese and bread. Not considered extremely dangerous, but sometimes it can affect some internal organs. This usually happens rarely with people whose body has very weak protective functions. Blue Rarely appears in houses, does not pose a danger to humans. It grows mainly on trees and is used in the production of exquisite cheeses. The appearance is a bloom of blue. Gray Gray (saprophytic) mushrooms look like a simple bloom. Settles on almost any surface and covers a variety of materials. Sometimes it infects food (vegetables, fruits) and spreads through flower seeds.
