Entoloma rodwayi, known as the green stem pinkgill, is a species of fungus
in the Entolomataceae
family of mushroom
s. A yellowish green mushroom with pink gills and spores, it is found in wet forests of Tasmania.
in 1898, it was transferred to the genus Entoloma
in a 1980 publication by German mycologist Egon Horak. It was named after Tasmanian botanist Leonard Rodway

The genus Entoloma is well represented in Australia, particularly Tasmania, and E. rodwayi is one of many unusually coloured members, others being shades of blue and purple as well as green.

When dried, the mushroom transforms from yellow-green to a vivid blue-green. It can be confused with some other green mushrooms such as the larger and more solid Cortinarius austrovenetus and several species of Hygrocybe
