Abstract

From 38 samples of green fungal contaminated wood logs, sawdust in polypropylene bags and other related materials used for shiitake (Lentinula edodes (Berk.) Pegler) production collected from five shiitake production houses, 43 isolates of fungi produced green spores were obtained. Twenty seven of which belonged to genus Trichoderma (62.8%), 9 were Gliocladium (20.9%), 4 were Penicillium (9.3%) and 3 were Aspergillus (7.0%). Among Trichoderma, 22 isolates (81.5%) were identified as T. harzianum, 2 isolates (7.4%) were T. piluliferum and 1 isolate each (3.7%) was T. aureoviride, T. koningii and T. pseudokoningii. It was obvious that T. harzianum was the predominant species and widely distributed in shiitake production houses compared with the other 4 species. All isolates of T. harzianum did not show any resistance to a fungicide, benomyl.
