Asian deceiver
Laccaria vinaceoavellanea is a small ectomycorrhizal mushroom sold as food in Yunnan and Sichuan, and it accumulates arsenic in its caps, which the sources treat as a main safety caveat.
Mushrooms
Butyriboletus huangnianlaii
Butyriboletus huangnianlaii is a Chinese butter bolete described from Fujian and later found at market in Pu’er, Yunnan. The local edible label is limited evidence; recurring season and preparation remain unestablished.
A distinct butter bolete
Species Fungorum accepts Butyriboletus huangnianlaii N.K. Zeng, H. Chai & Zhi Q. Liang, a species described in 2019. A four-locus phylogenetic analysis placed the two studied collections together as a distinct lineage within Butyriboletus. The protologue distinguishes it from related species including B. pseudospeciosus and B. roseoflavus; similar bolete traits should not be treated as interchangeable identification clues.
The published description gives a dry, finely tomentose pale-brown to reddish-brown cap, yellowish flesh and pores that turn blue quickly when injured, and a solid central stem that darkens reddish-brown with net-like reticulation nearly to its base. It is ectomycorrhizal, and the type forest was dominated by Castanopsis kawakamii. This is a summary of a technical taxonomic description, not a field key or consumption advice.
A Fujian type record and a Yunnan market record
The type and a second cited collection were made at Geshikao National Forest Park, Sanming City, Fujian Province, southeastern China, at 420 metres. The holotype was collected on 16 August 2017; the second collection is from the same site and date. The authors describe the distribution as southeastern China, a limited published record rather than a complete range map.
A 2022 survey of markets and nearby forests in Pu’er Prefecture, Yunnan, lists voucher HKAS-111755 in its market column, not its natural-habitat column. The row also marks the species ectomycorrhizal and labels it edible. The paper does not specify which market, a collection date, or a forest locality for this species.
Season and documented use
August is the date of the Fujian type collection, not an established fruiting season. The Pu’er study spans three years, but it does not state when HKAS-111755 was recorded. General market peaks for other mushrooms in the survey cannot be assigned to this species. No source reviewed here establishes a recurring fruiting window.
The Yunnan survey records the species at market and applies an edible label, but gives no species-specific recipe or preparation method. This supports a local market record and the authors’ edible classification; it is not an independent toxicological evaluation or a universal safety statement. Related boletes can share visible traits, so this entry is not a specimen-identification or personal-consumption guide. No recipe, processing temperature, or preservation instruction is added without direct evidence.
