The emergence of an unusual Agaricus bisporus mushroom disease first reported in the UK, and later termed as “mushroom virus X” (MVX), exhibits a wide range of symptoms. Findings from laboratories in the UK, the Netherlands and Ireland indicate that symptomatic MVX mushrooms contain a variable compendium of novel 26 (dsRNA) elements, ranging in size between 20.2 kb and 0.64 kb. Four low molecular weight dsRNA bands (sizes 2.0–0.64 kb) are consistently synchronous to mushroom off-color/browning symptoms. This devastating disease first appeared in 1996 on UK farms. MVX is now more widespread and prevalent in a number of European countries (e.g. Netherlands, Ireland). Symptoms vary and range from the occasional outbreak to severe outbreaks leading to crop losses. Recently a few mushroom farms in Poland reported symptoms of brown-colored mushrooms among the white ones. These observations were very similar to the observations of MVX incidences observed before on Dutch farms. This work is probably the first information about the possible presence of MVX on Polish mushroom farms.
