Sordaria fimicola (Ascomycota, Sordariales) on Acer palmatum

Abstract

During an investigation of the mycoflora of Japanese red maple trees growing in an urbanized area of Nitra, Slovakia, Sordaria fimicola (Roberge ex Desm.) Ces. & De Not) was isolated from affected leaves and branches of Acer palmatum ´Atropurpureum´ L. This fungus was associated with symptoms of brown wood discoloration and leaf spottiness of these trees. Sordaria fimicola was recorded for the first time on Acer palmatum ´Atropurpureum´ in Slovakia. The fungus is characterized by dark brown ascomata clothed with setae, fasciculate, unitunicate, cylindrical asci, and olivaceous to olivaceous-brown, one-celled, ellipsoidal, smooth-walled ascospores with a colourless basal germ pore and surrounded by a gelatinous sheath.
