 The mycorrhizal associations of several Sclerodermatineae genera have been established . Studies have demonstrated that Astraeus , Pisolithus , and Scleroderma form ectomycorrhizal associations with both angiosperms and gymnosperms . Previously thought to be saprophytic , the Calostomataceae were determined to be ectomycorrhizal with Fagaceae and Myrtaceae using isotopic and molecular analyses . Species from the genera Pisolithus and Scleroderma have been used in forestry as mycorrhizal inocula to help promote the growth and vigor of young seedlings .
