Abstract: Study on the mycoflora in dried products of laver was carried out. Fifty three samples of dried laver were collected from its main producing area on the coastland of Fujian and from the markets. The fungal colony counts were determined on rose bengal agar plates incubated at 27℃ and moulds were classified. Mould was found in all the samples shown 100％ positive with total counts ranging from ＜5～1.2×10４CFU/ｇ-1. In the fresh samples collecting from the producing area, fungal quantity was lower and Fusarium was the genus found most frequently. This field mould is the commonly autochthonous flora of plant. The dried lavers obtained at the market stage yielded greater counts. Asperｇillus ornatus, A. niger, A. versicolor etc. were the dominan tgroup. They are common storage mould. It was believed that the contamination of these moulds was a result of improper storage, transportation and sale. It suggests a maximun guideline of mould count of 2.0×10２ CFU/ｇ－1 in dried products of laver.
