Sclerotia Formation of Phlebopus portentosus under Natural and Artificial Conditions

Phlebopus portentosus is a favorite wild, edible mushroom in the tropical region of China and northern Thailand. P. only bolete Boletales order that has been commercially cultivated. Sclerotia produced by are often found its natural habitats cultivated media. These sclerotia play key role life cycle. However, regularity growth characteristics sclerotium unknown. In this paper, whole process birth, growth, death rebirth under lab conditions reported for first time. Sclerotium formation nature due to environmental stress, such as drought or low temperature. The less rainfall, more produced. It appears lower temperature can also initiate formation; however, relationship between not clear rainfall. Under artificial conditions, related fungus’ physiological maturation. presence always accompanied exudation liquid droplets on colony. results study should provide platform research importance cycle portentosus.
