About Lactarius eucalypti O.K.Mill. & R.N.Hilton
Lactarius eucalypti is a species of milk-cap fungus belonging to the family Russulaceae. This species is found in Australia, and was formally described as new to science in 1987 by Orson K. Miller, Jr. and Roger N. Hilton. These mushrooms grow on the ground in woodlands dominated by jarrah (Eucalyptus marginata), karri (Eucalyptus diversicolor), and marri (Corymbia calophylla). Fruiting generally only occurs in years with higher rainfall, and mushrooms appear during the months of May and June. The cap is orange-brown and convex when young, and may become flat as the mushroom ages. It measures between 1.8 and 3.1 cm across.
