Abstract

Objective Two varieties closely related to Lactarius delicious found in the wild in Guizhou were morphologically and molecularly identified and homology analyzed.
Method Two species of Lactarius from a Pinus massoniana forest in Hejiang Village, Meitan County were examined on their morphological features under a microscope and on their phylogenetic characteristics by ITS rDNA sequence.
Result The two mushroom varieties were identified to be L. vividus and L. hatsudake. Between them, significant discrepancies in morphology and ITS phylogeny were evident. L. vividus was 95% homologous with L. deliciosus, while L. hatsudake slightly lower at 93%.
Conclusion The information provided a concrete basis for the species identification facilitating the conservation, domestication, research, and utilization of the rare and valuable Lactarius in the wild.
