Eleven species of mycorrhizal fungi, selected from stands of either Eucalyptus spp., Allocasuarina spp. or Pinus radiata D. Don were tested in an aseptic system for their abilities to initiate ectomycorrhiza with Allocasuarina littoralis (Salisb.) L. Johnson, Casuarina equisetifolia ssp. equiselifolia L. and C. cunninghamiana Miq. Elaphamyces sp., Hysterangium sp., Laccaria laccata (Scop ex Fr.) Bk. & Br., Pisolithus tinctorius (Pers.) Coker & Couch, Scleroderma sp. and Thelephora terrestris (Ehrh.) Fr. formed ectomycorrhizas on all three hosts. Amanita sp. formed ectomycorrhizas on A. littoralis and C. cunninghamiana but not on C. equisetifolia. Paxillus involutus (Batch ex Fr.) Fr. formed ectomycorrhizas on A. littoralis only. P. tinctorius also formed ectomycorrhizas with C. obesa Miq. Rhizapogon luteolus Fr. & Nord, Suillus granulatus (L. ex Fr.) Kuntze and S. piperatus (Bull ex Fr.) O. Kuntze colonized the rhizosphere of Casuarinaceae but did not form ectomycorrhizas. The comparative intensity of ectomycorrhizal infection by P. tinctorius and L. laccata was assessed on four host species. Infection intensity ranged from 13 to 70%, of laterals infected and decreased for both fungal species in the order: A. littoralis > Eucalyptus pilularis Smith > C. equisetifolia > C. cunninghamiana. An exogenous supply of glucose induced greater and sometimes earlier, ectomycorrhizal infection of A. littoralis, C. equisetifolia and C. cunninghamiana by P. tinctorius and L. laccata than that in the absence of glucose. The optimum glucose level for these fungi and hosts in this synthesis system was 750 μg glucose (g soil) .
从桉属植物、异木麻黄属植物或辐射松的林分中选出11种菌根真菌，在无菌系统中测试它们与滨海异木麻黄、木麻黄原亚种和细枝木麻黄形成外生菌根的能力。埃氏块菌属、空柄块菌属、乳白红菇、彩色豆马勃、硬皮马勃属和土生棱柄盘菌能在所有三种寄主上形成外生菌根。鹅膏菌属能在滨海异木麻黄和细枝木麻黄上形成外生菌根，但不能在木麻黄原亚种上形成。卷缘桩菇仅在滨海异木麻黄上形成外生菌根。彩色豆马勃也能与粗枝木麻黄形成外生菌根。黄须腹菌、颗粒牛肝菌和胡椒牛肝菌定殖于木麻黄科植物的根际，但未形成外生菌根。在四种寄主植物上评估了彩色豆马勃和乳白红菇外生菌根感染的相对强度。感染强度在被感染侧枝的13%至70%之间，两种真菌的感染强度均按以下顺序降低：滨海异木麻黄＞毛果桉＞木麻黄原亚种＞细枝木麻黄。外源供应葡萄糖比不供应葡萄糖时能诱导彩色豆马勃和乳白红菇对滨海异木麻黄、木麻黄原亚种和细枝木麻黄形成更强且有时更早的外生菌根感染。在这个合成系统中，这些真菌和寄主的最佳葡萄糖水平为750微克葡萄糖/（克土壤）。
