Yellow-stemmed bolete

Loading ratings…

Boletus auripes, the yellow-stemmed bolete, is a forest bolete with yellow fruit bodies under a brownish cap. The catalogue records a regional food use in Mexico, and the paper behind that record could not be read.

Two whole brown-capped, yellow-stemmed boletes and two lengthwise halves showing yellow flesh and pores rest on a warm ivory surface.

Overview

The yellow-stemmed bolete, Boletus auripes, is a forest bolete. Its fruit bodies are yellow apart from a brownish upper cap, and the species is known in English as the butter-foot bolete. It grows in woodland as an ectomycorrhizal fungus, a partner of tree roots, and the catalogue describes it as a wild food record.

Food use and the Mexican record

The catalogue records a regional bolete food use in Mexico and cites a 2017 paper in the Journal of Ethnobiology and Ethnomedicine for it. That paper could not be opened for this page, so the local names, the preparations and the extent of use in Mexico are not recorded here.

The Wikipedia entry for the species lists it as edible. That general statement is not a local food record, and it does not establish how the mushroom is prepared or how widely it is eaten.

Habitat

The catalogue describes the habitat as forest and the association as ectomycorrhizal. The host tree and the fruiting season are not given in the evidence read for this page, so neither is stated here.

Safety and what is not known

No safety assessment of this species was found in the evidence read. Boletes are a difficult group to identify, and several look-alikes differ in edibility, so identification should be confirmed by a qualified expert before any use. Nothing on this page is advice for collecting or identifying wild boletes.

A fuller account would need the Mexican ethnomycological paper, the local names it records and any measured toxin or processing data.
