The invention belongs to the fields of microorganisms and microorganism application and particularly relates to Rhizopycnis sp. NYN8C05 and application thereof to lowering of heavy metal absorption of tobacco. The Rhizopycnis sp. NYN8C05 is characterized in that a bacterial colony is slow in growth and is ash black, and villous grey mycelia grow on the surface of the bacterial colony; the colors of the back of the bacterial colony changes from grey to ash black, a light-color annulation is formed between the grey part and the ash black part, and the back of the bacterial colony is of an evident annulation shape; mycelia are dark and separated and have multiple branches, chlamydospores are spherical and have unsmooth surfaces, and multiple chlamydospores are serially connected to form a chain; the sequence analysis of an ITS rDNA area is identified as Rhizopycnis sp., and the ITS sequence is as shown in sequence No. 2.
