Summary

Austroboletus olivaceoglutinosus sp. nov., is described from subalpine coniferous forest in northern Sikkim, India. It can be immediately recognised in the field by its glutinous, olive (often umbonate) pileus, overhanging margin that covers the hymenophore completely in young basidiomata, white to yellow lacunose-reticulate or lacerate, exceptionally long (100 – 180 × 13 – 17 mm) stipe and a strong fruity odour. Its relationship with allied taxa is discussed.

Key Words
