Effect of microscopic fungi isolated from flax stems on fibre strength.
According to their effect on the intensity of decomposition of bast fibres, 25 spp. isolated from flax stems were divided into 5 groups. Decomposition by Alternaria and Penicillium spp. was strong and by Chaetomium, Acremonium, Stachybotrys and Trichoderma spp. extremely strong. This last class also included flax pathogens such as Colletotrichum lini [C. linicola], Phoma exigua var. linicola and Botrytis cinerea f.sp. lini.
