The ascomata andmycorrhizae of Tuber indicum s.l. were collected under the forest ofbroad-leaf species Populus yunnanensis and Quercus pannosa in the fieldrespectively. The symbiotic relationships of both trees with T. indicum were examined and affirmedbased on morphology and ITS-rDNA sequences. These two mycorrhizal combinationswere successfully produced on artificially controlled substrates and culturalcondition. This is the first report of a mycorrhizal association andsynthesis between Chinese black truffles and poplars. A hyphal net covering themantle’s surface of the mycorrhizae was detected in both mycorrhizalcombinations. The mycorrhizal colonization of P. yunnanensis and Q. pannosa suggests that T. indicum s.l. has a broader host range and thatadditional corresponding wood species would be used as candidates for thecultivation of T. indicum. Thenuclear-ITS sequences of the mycorrhizae included in the phylogeny of the T. indicum complex revealed that the twoclades within the complex do not markedly differ with respect to theirpreferences for host species or geographical origin. Our results help toexplain the wide distribution of both clades of the T. indicum complex. It would be more important for truffle conservationand Chinese black truffle plantation development with these two dominated &alpestrine Populus yunnanensis and Quercus pannosa at subalpine limestoneareas in China.
