Lactarius vesterholtii, a new species from India

Lactarius vesterholtii is proposed as new to science. It is characterized by a greyish brown dry subvelutinous pileus, very crowded light yellow lamellae turning orange when bruised, white copious latex becoming reddish orange in contact with the lamellae, a light yellow spore print, amyloid basidiospores ornamented with high ridges that forms an incomplete reticulum, the absence of pleuro- and cheilomacrocystidia, a trichopalisade to lamprotrichopalisade-type pileipellis, and a palisade to lampropalisade-type stipitipellis. The new species is compared with allied Asian and extralimital taxa. A key to the Indian taxa of L. subg. Plinthogali is also provided.
