A Russula (Basidiomycota, Russulales) with an unprecedented hymenophore configuration from northwest Himalaya (India)

The authors describe a Russula in section Cyanoxanthinae with a stipe surface that is entirely covered by a hymenial layer in the form of a reticulate-veined extension of the gills all the way down to the stipe base, a hitherto unknown phenomenon in the family Russulaceae. The significance of this finding is discussed.
