Not Russula neerimea, the cap and gill colours are wrong (should be yellowish/buff) and the cap lacks the marginal striations, see the species information Heino has provided. It is possibly Russula persanguinea as the cap appears to be only of a red colour and the gills and stipe seem pure white.
I agree with Ken. A good link to see what R. neerimea looks like is: https://www.dpaw.wa.gov.au/images/documents/about/science/fungus/45_2010-11_Russula_neerimea_DEC_FF.pdf
Most probably Russula persanguinea from what I can see. This species has a bright red cap with white gills and stipe (stem). At times the stipe may have slight blush of pink.
