Abstract
Hericium erinaceus (Bull. : Fr.) Pers. is an edible and medicinal mushroom is very popular in traditional Eastern Medicine and has been used to treat different human illness and known for strengthening the immune system and neurological health of mankind.
For this reason, it has received considerable attention worldwide. Hericium erinaceus is a toothed fungus characterized with long spiny hymenophore that makes it a white snowball shape. Present research work was started with the objectives of evaluating
strains (He-101, He-102, He-104, He-105, He-107, He-108, and He-109) of Hericium erinaceus and substrates (wheat straw/ poplar sawdust) along with In vitro study of mycelium growth of the best-selected strain(s) in different media, temperature, and pH.
Morphological characterization of the strains was also done. The strain He-108 completed spawn run within 24 and 26 days on growing media 1 and 2, respectively. However, He-101 and 104 harvested early from growing medium 1 within 42 and 43
days after spawning. It was invariably found that among all strains, He- 104 demonstrated the highest 205.7 g yield /1.5 kg growing medium 1 (31.65% biological efficiency) at 15-20oC temperature with an average 10.70 numbers of mushroom. This
yield was achieved from maximum number of 5 harvestings of total cropping period of 101 days. The performance of growing medium 1 was found superior than to that of growing medium 2.The average biological efficiency of 17.66 % with the total number
of 7.26 fruits were recorded with growing medium 1 than to that of an average 3.21% BE and 1.98 total number of fruits obtained from growing medium 2. As a result, the strain He-104 showed maximum 89.56 mm diametric growth in vitro on PDA of pH 5 at 25°
temperature. A morphological study of the above strains was also done using a mature fruit body. The fruits of He-101, He-104, He-107, He-108, He-109 were categorized into clump type. He-105 had thick branching type sporophores and He-102 was known with diffuse branching type sporophores. Microscopic study for the dimension of basidia and spore showed that they were ranged from 27- 45 X 5.20-7.51 μm and 5.20- 6.90 X 4.20-5.80 μm in the size, respectively.
