Abstract

The growth of Odontia bicolor in soil and in balsam fir wood was studied. In steam-sterilized organic soil, the fungus grows rapidly, producing a scanty and uniform growth, whereas in propylene oxide gas-treated or natural organic soil, it forms mycelial strands. In mineral soil, the fungus reacts as in organic soil except that growth is more sparse. The fungus grows through natural soil and colonizes new substrate more rapidly when mycelial strands are linked to an appropriate food base.

The optimum temperature for growth on a 2.5% malt extract medium occurs between 22 and 27°C. The fungus grows well in balsam fir wood at any moisture content above 42% of the oven-dry weight, and twice as fast in sapwood as in heartwood. Its growth is not influenced by previous storage of the wood, either frozen (-20°C) or at a temperature of 2 °C for up to 16 weeks.
