Lactarius subdulcis - Mild Milkcap

Lactarius subdulcis - Mild Milkcap

Taxonomy

Phylum: Basidiomycota

Class: Agaricomycetes

Order: Russulales

Family: Russulaceae

Another of the small milkcaps commonly found in broadleaf woods, Lactarius subdulcis is mycorrhizal with Beech trees, but it also occurs under birches and occasionally under deciduous oaks. This is a difficult milkcap to identify with certainty because is has so many lookalikes.

Caps of Lactarius subdulcis store abundant, sweet-tasting white milk. The specific epithet subdulcis literally means 'under sweet' - a reference to the delayed sweet taste.
