Abstract
In this study, an unknown mushroom species collected on rotting trunks of Ficus elastica in the Hanoi Botanical Garden was investigated. It was designated as Bt116. Based on the observed morphological characteristics, such as irregularly semi-circular, slightly yellow pileus; very soft, homogeneous, spongy, creamy white context; short and not clear stipes; and basidiospores typical of ganoderma mushrooms, etc., we hypothesized that Bt116 belongs to the Tomophagus Murr. mushroom genus. Some biological characteristics of the Bt116 strain were made. The results indicated that the temperature 35°C was optimal for Bt116 mycelial growth; an alkaline environment (pH 8.0) was conducive for the mycelial growth of Bt116 among a range of pH levels from 4.0 to 9.0; aerobic conditions were better than anaerobic conditions for the growth of Bt116 mycelium; and lighting time showed no significant effects on the growth of Bt116 mycelium.
