Investigation of soil environments in the vicinity of Tricholoma matsutake mycelium in Abies sachalinensis stands

Abstract

To understand the habitat of Tricholoma matsutake in Hokkaido, we investigated the soil environment in an Abies sachalinensis plantation where this fungus colonized. As a result, soil pH and microbial quantity (colony forming unit; cfu) showed lower trend around the colony of T. matsutake than those areas where this fungus was not colonized. In addition, soil temperature was maintained over 0℃ even in the mid-winter despite the minimum air temperature recoded below −20℃, due to snow cover on the forest floor.
