The natural occurrence of Pisolithus tinctorius has been confirmed in 33 countries of the world and in 38 states in the United States. This ectomycorrhizal fungus is found associated with various tree species in nurseries, urban areas, orchards, forests, and strip-mined spoils. Experiments have proved that this fungal symbiont forms ectomycorrhizae with Abies procera, Betula pendula, Carya illnoensis, 11 species of Eucalyptus, 30 species of Pinus, Pseudotsuga menziesii var. meniziesii, 2 species of Quercus, and Tsuga heterophylla. Pisolithus has also been reported growing under natural conditions in association with three additional species of Betula, two species of Eucalyptus, nine species of Pinus, and eight species of Quercus, Populus tremuloides, Pseudotsuga grandidenta, and Salix humilis. This fungal symbiont has great potential in forestation efforts because of (1) the availability of practical techniques for artificially introducing in into nursery soils; (2) its ability to improve tree survival and growth in the nursery and the field; (3) its near worldwide distribution on a variety of sites; and (4) its broad host range encompassing many of the world's most important tree species.
世界上已有33个国家以及美国的38个州证实了彩色豆马勃的自然分布。这种外生菌根真菌与苗圃、城市地区、果园、森林和露天矿废弃地中的各种树种共生。实验证明，这种真菌共生体可与美国冷杉、垂枝桦、山核桃、11种桉树、30种松树、北美云杉、2种栎树和异叶铁杉形成外生菌根。据报道，彩色豆马勃在自然条件下还与另外3种桦树、2种桉树、9种松树、8种栎树、颤杨、大齿云杉和矮柳共生。这种真菌共生体在造林方面具有巨大潜力，原因如下：（1）有将其人工引入苗圃土壤的实用技术；（2）能够提高树木在苗圃和田间的成活率及生长量；（3）几乎在世界范围内的各种地点都有分布；（4）寄主范围广泛，涵盖了许多世界上最重要的树种。
