In Guyana, the humic deposits on "Dicymbe" trunks bearing "B. ananas" are consistently permeated with abundant ectomycorrhizas. The fungus was reported as forming mycorrhizal associations with eucalypts in Australia, based on fruit body association with trees. Its North American distribution encompasses a range extending north from North Carolina to Florida, west to Texas and south to Mexico, and Central America. In 2008, it was reported for the first time in the Upper Potaro and Upper Ireng River Basins in Guyana. It has also been collected from New Zealand, Asia (including China, Korea, Malaysia, and Taiwan), and possibly Australia.
