Diseased fruit bodies of Agaricus bisporus, bearing symptoms similar to those caused
by Verticillium fungicola and Mycogone perniciosa, were observed during the screening of
eight mushroom farms in Serbia in 2002 and 2003. Nine isolates, forming either appressed
white or pale brown colonies on PDA medium, were recovered. The isolates were identified
on the basis of their morphological, physiological and pathogenic characteristics, and
by comparing them to V. fungicola var. fungicola and M. perniciosa isolates originating from
United Kingdom, and V. fungicola var. aleophilum from the USA. Pathogenicity of these isolates
was confirmed by casing inoculation, on which occasion symptoms of both dry and
wet bubble disease were recorded. Five isolates were identified as Verticillium fungicola
(Preuss) Hassebrauk var. fungicola (W. Gams & Van Zaayen), and four as Mycogone perniciosa
(Magnus) Delacroix. Plodonosna tela Agaricus bisporus sa simptomima
nalik onima koje izazivaju Verticillium fungicola
i Mycogone perniciosa primećena su u osam gajilišta u Srbiji tokom 2002. i 2003. godine.
Dobijeno je 9 izolata patogena koji obrazuju
supstratne bele ili svetlo smeđe kolonije
na PDA podlozi. Izolati su identifikovani na osnovu
morfo-fizioloških karakteristika i patogenih
osobina a determinacija potvrđena poređenjem
sa kontrolnim izolatima V. fungicola var.
fungicola i M. perniciosa iz Velike Britanije
i V. fungicola var. aleophilum iz SAD. Veštačkim
inokulacijama pokrivke za gajenje A. bisporus,
dobijenim izolatima, pojavili su se simptomi suve
i mokre truleži. Pet izolata je identifikovano kao Verticillium fungicola (Preuss) Hassebrauk var.
fungicola (W. Gams & Van Zaayen), a četiri
kao Mycogone perniciosa (Magnus) Delacroix.
