Mulch helps to regulate soil temperature and retain moisture, which is essential for the growth of truffles. 2. Keep them dry: Truffles are highly prone to moisture, so retaining them as dry as possible during storage is important. 6. Freeze for long-term storage: If in case you have many black summer season truffles, you might want to consider freezing them for lengthy-time period storage. To understand the molecular underpinning of the ectomycorrhizal truffle way of life, we in contrast the genomes of Piedmont white truffle (Tuber magnatum), Périgord black truffle (Tuber melanosporum), Burgundy truffle (Tuber aestivum), pig truffle (Choiromyces venosus) and desert truffle (Terfezia boudieri) to saprotrophic Pezizomycetes.
