Hed Na (Agaricus sp.) is an edible wild mushroom collected on sandy soil near Samira beach, Songkhla Province. The identification of this mushroom is still inconclusive Dikaryotic mycelium of Hed Na was isolated by tissue culture into potato dextrose agar and used to study some physiologic aspects and cultivation potential. Hed Na mycelium grew well on corn meal agar. Maltose is the best carboon source in supporting mycelial growth. Hed Na utilized peptone better than other nitrogen sources. The optimal temperature and pH on malt extract agar were 25 deg C and 5-6, respectively. Light retarded mycelial growth of Hed Na. Hed Na could be artificially cultivated in plastic bags using rice straw and boiled sorghum grain (1:1, by volumn). Time required for mycelial growth in 500 g of substrate was 168.5 days. The spawn was incubated for 30 days before casing with sand soil and transferring to a mushroom house. Fructification began after 42 days of watering. The first flush obtained was 38 g/bag. In this study, mass production of Hed Na in plastic trays using composted rice straw, sawdust and kapok waste was not successful.
