The emergence of an unusual Agaricus bisporus mushroom disease first reported in the UK, andlater 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 onUK farms. MVX is now more widespread and prevalent in a number of Europeancountries (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 MVXincidences observed before on Dutch farms. This work is probably the firsti nformation about the possible presence of MVX on Polish mushroom farms.

W 1996 r. w Wielkiej Brytanii, po raz pierwszy, odnotowano pojawienie się nietypowej choroby w uprawach pieczarek (Agaricus bisporus), nazwanej “Mushroom Virus X” (MVX). Choroba ta wykazuje szereg zróżnicowanych objawów. Wyniki prac przeprowadzonych w Wielkiej Brytanii, Holandii i Irlandii wskazują na to, że grzyby z objawami MVX zawierają zróżnicowany zestaw do 26 elementów dsRNA o wielkościach w przedziale 20,2 do 0,64 kpz. Występowanie czterech najmniejszych frakcji dsRNA (2,0–0,64 kpz) jest wyraźnie skorelowane z obecnością charakterystycznych symptomów chorobowych – brązowych, lub przebarwionych kapeluszy pieczarki. Ta groźna choroba, staje się coraz bardziej rozpowszechniona w szeregu innych krajów europejskich (np. w Holandii, Irlandii), wykazując zróżnicowane objawy oraz różne nasilenie – od pojedynczych przypadków aż do istotnej redukcji plonu. W ostatnim czasie kilka gospodarstw w Polsce donosiło o pojawieniu się brązowych grzybów występujących wśród białych owocników. Objawy te były bardzo podobne do wcześniej obserwowanych w holenderskich pieczarkarniach. Prezentowana praca stanowi prawdopodobnie pierwsze doniesienie o możliwej obecność wirusa X w uprawach pieczarek w Polsce.
