Stropharia rugosoannulata is an amazing species I love encountering on my fungal forays. Usually found on woodchips, the species clearly breaks down woody material. However, what makes wood an efficient tissue to synthesize for plants, does not make it a prime food source for fungi. A strategy this forest floor inhabitant has in its repertoire is a unique mechanism to trap nematodes and absorbs the nutrients within the organisms to supplement its otherwise nutrient poor woody diet.
