yes. they are microscopic because they are single-cellular organisms.
Fungi will fall under a group of organisms that are known as microbes. The other organisms in this group include archea, bacteria, protists and viruses.
Archea Bacteria are a domain of organisms that live in extreme environments.
BacteriaProkaryotes can include bacteria and archea. There are three domains of life, Bacteria, Archea, and Eukaryotes. The domains of Bacteria and Archea are made up from prokaryotic organisms, which are usually unicellular.

Archea
Bacteria and Archea (Archbacteria)
bacteria and archea
Plantae: Consists of all plants that are capable of photosynthesis. Protista: Includes various algae species that can perform photosynthesis. Bacteria: Some species of bacteria, such as cyanobacteria, are photosynthetic organisms.
Prokaryotic organisms have no nucleus. This includes all bacteria, including the archea and cyanobacteria.
Protists are eukaryotes. They are cells with a nucleus. Bacteria and archea are generally much smaller than nucleated cells and they have no nucleus. The mitochondria and chloroplasts in nucleated cells are about the size of bacteria and apppear to be descendants of bacteria that lived symbiotically within cells that evolved into cells with a nucleus.
Eukaryotic organisms (basically anything that lives except bacteria and archea)
Protists and bacteria are two completely different kingdoms of life. Protists are eukaryotic, meaning that their DNA is stored in chromosomes within a nucleus. Bacteria are prokaryotic, and do not have nuclei. Also, protists are sort of like the miscellaneous category. There are plantlike cells (such as diatoms) and animal-like cells (such as ameoba). Bacteria and protists also have different shapes to their cells and different organelles.
