Super water absorbent (CPAM-AS-hyd-1) was prepared by polymerization of acrylamide and allyl sulfonate salt with N,N'-methylene-bis-acrylamide as crosslinking agent, followed by alkaline hydrolysis and the effect on mycelial growth and sporophore production of edible mushrooms in the artificial cultivation was examined. The mycelial growth of edible mushrooms did not depend on the addition of super water absorbent upto 200 g of hydrated polymer gel per 100 cc medium. The proper hydrated polymer gel concentration for sporophore production of Pleurotus sajor-caju and Hericium erinaceus were 200 g and 200~250 g per 100 cc medium, respectively. The proper hydrated polymer gel and puffed rice hull concentration for sporophore production of Flammulina velutipes was 200 g per 100 mm medium and 10% (v/v), respectively.
