The distribution and diversity of RNA viruses in fungi is incompletely understood due to the often cryptic nature of mycoviral infections and the focused study of primarily pathogenic and/or economically important fungi. The first cases of mite mycoses were described about 70 years after the recognition of the infective character of insect mycoses and this delay remained until the 1970s, except for a few subtropical and tropical institutes, where mycoses of mites had been included into some research, but usually on a very limited scale (e.g., Fisher 1950, 1951). field_rates 0.
