Lactifluus rubroviolascens

What it is

Lactifluus rubroviolascens is a milkcap that was first described as Lactarius rubroviolascens by R. Heim in 1938 and was later moved by Verbeken into the genus Lactifluus. The older name Lactarius rubroviolascens is still used as a search name, and the species is recorded under both.

Field characters noted in the sources include an orange-brown colour, watery latex, and red spots at a wound that turn quickly black. Those features help separate it from other milkcaps, but the sources do not establish a complete list of look-alikes, and Lactarius chromospermus, a miombo species, is named as a different species that is not regarded as edible.

Habitat and distribution

The species is ectomycorrhizal, so it lives in partnership with the roots of woodland trees. Recorded habitats include miombo woodland, where it is associated with Marquesia macroura, and wooded savanna where it is associated with Uapaca kirkiana and Uapaca pilosa. The sources describe a wide ecological range across woodland, savanna and forest.

The recorded distribution covers Benin, Cameroon, the Democratic Republic of the Congo, Kenya, Madagascar, Malawi and Zambia. These are records in the sources, not a survey of the species range, and the entry gives no abundance or season.

Food status

The EFTA edible-species inventory records the species as a regional milkcap used for food. Taxonomic sources list it among edible fungi, including a French guide to the edible mushrooms of Upper Katanga and a guide to the edible fungi of Central African dense forests. No consulted source gives a preparation, a cooking method or a local name for the species.

The catalogue record keeps the food status as an institutional record, with preparation, identity and current safety still needing separate validation. No source consulted gives a toxicity finding for this species, and none establishes a safe method. A regional mycologist should be consulted before any wild milkcap is eaten.

What is still open

The open questions are the local harvesting and preparation practices, the toxicity of the species, and whether the field characters hold across the full recorded range. The current genus placement also needs confirmation against the full monograph, which the consulted sources summarise but do not reproduce. Until those are answered, the page can say that the species is a recorded edible milkcap, and no more.
