Lactarius tenellus

What it is

Lactarius tenellus is a milkcap, a member of the genus Lactarius, which produces latex when its flesh is cut. It grows in the woodlands of central, eastern and western Africa and is associated with the trees of the miombo woodland.

The EFTA species page describes its fruit bodies as smaller than those of its close relative Lactarius kabansus, with a strongly crenellated cap margin. The orange tinge at the base of the stipe, which is characteristic of L. kabansus, is absent in L. tenellus. The page notes that the two can grow together, so these features are worth checking before any specimen is collected.

The species has a complicated naming history. Verbeken and Walleyn treated it as a variety of Lactarius kabansus before giving it a separate status in a 2001 synopsis of tropical African Lactarius, where it received a replacement name, Lactarius tenellus Verbeken and Walleyn nom. nov. The older name Lactarius kabansus var. pallidus is still used as a search alias in some catalogues. The Verbeken and Walleyn monograph of 2010 is the main taxonomic reference, and it was not available for this page.

Where it is recorded

The EFTA entry lists known records from Benin, Burundi, Cameroon, the Democratic Republic of the Congo, Côte d'Ivoire, Kenya, Malawi, Niger, Tanzania, Togo, Zambia and Zimbabwe, and places the species mainly in the Zambezian miombo. These are records of the species in the sources, not a survey of its range, and the entry gives no abundance or seasonal information.

Tanzanian ethnomycology notes that many Lactarius species are regarded as edible in Tanzania, although opinions differ between tribes and some of them contradict each other. That observation covers the genus across the country and cannot be read as a statement about L. tenellus in particular.

Food status

The EFTA page does not state that Lactarius tenellus is edible. It describes its close relative Lactarius kabansus as an edible species and treats L. tenellus as a related form that was once part of it. The page gives no preparation or cooking advice for L. tenellus.

The workbook record that brought this species into the catalogue flags it as an institutional edible-species record, with preparation, identification and current safety still needing separate validation. This page does not change that status. Lactarius species are difficult to separate from one another in the field, so catalogue inclusion is not a basis for identifying a specimen or deciding whether to eat it.

Ecology and what remains unknown

The species is ectomycorrhizal, meaning it lives in partnership with the roots of woodland trees. The EFTA entry associates it with Brachystegia, Julbernardia, Isoberlinia and Uapaca in miombo woodland. No consulted source describes its seasonality, its flavour, its texture or any local name in use.

The main open question is whether any community gathers and eats this species with an identified preparation.
