Yes, termite garden-associated Xylaria, often referred to as Pseudoxylaria, are primarily adapted to termite fungus combs. However, they can occasionally be found in soil, particularly near termite nests, and less frequently on woody substrates. These occurrences outside termite environments are likely opportunistic. Molecular and ecological studies suggest that while related Xylaria species are widespread in wood and soil, the termite-associated group represents a specialized lineage with strong host and niche specificity.
