About this fungus

Rufous Milkcap is a fungus in the Russulaceae family. Its habitat and field characteristics are summarised below.

A dry, matt red-brown milkcap with a small central bump, pale gills and white latex, usually found with pine or other conifers.

What to check

Look for an unzoned brick-red to rufous-brown cap, pale gills running slightly down the stem, white latex that remains white, and a white to cream spore print. The stem has no ring or volva.

Variation

Caps range from bay or brick-red to darker red-brown and may fade when dry. Older gills can become patchy or pale reddish-cream.

Lookalikes

Lactarius subdulcis is usually smaller and linked mainly with beech. Other red-brown milkcaps overlap in cap colour and latex appearance, and regional identification may require spores or microscopy.

Habitat and range

Mycorrhizal mainly with pine and spruce on acidic woodland soil, often among moss. Birch associations are also reported, and host emphasis varies across its northern temperate range.

Food safety

Inedible.

Photographs

A glimpse of the research.

Weather response

A repeatable weather association was found in the records, alongside the usual seasonal pattern.

Higher or lower ground?

Records tended to come from higher ground relative to other fungal records in the study.

These are patterns in recorded observations, not rules, forecasts or identification evidence. Local conditions and recording patterns can affect the findings.
