Those organisms belong to kingdom fungi. Exception is unicellular yeast(Saccharomyces). Organisms in fungi formed a link connection between unicellular and multicellular kingdoms. Their body is made of a network of thin tube like structures known as hyphae. The network is known as mycelium which is considered as the fungal body. The fungal is not properly-differentiated but is a primitive multicellular body.
