Tylopilus balloui, the burnt orange bolete, is a tropical bolete recorded as food in Guyana. Sources disagree on whether it is worth eating, and its species concept needs checking.
Tylopilus balloui is a bolete, a mushroom with a porous rather than gilled underside, of tropical forests in South America. Its common name in the sources is burnt orange bolete, and the catalogue gives the English label Ballou's bolete. Food use is recorded in Guyana, where the species grows with trees of the genus Dicymbe.
Sources list the species under several names, including Boletus balloui, Gyrodon ballouii, Rubinoboletus balloui and Tylopilus balloui. The catalogue treats the name as a research label. Its identification in the Guyanese survey was morphology-based, and the modern species concept needs checking before any record is taken as settled.
The species is ectomycorrhizal, meaning it grows in partnership with tree roots. The Guyanese records place it in forests dominated by the ectomycorrhizal legume genus Dicymbe. Guyana is the only country the catalogue lists for it.
The catalogue records that the Ackawaio use the mushroom as food, and that some Patamona later adopted it. The further search did not find independent confirmation of this Guyanese food use.
Sources disagree on the species. One describes it as edible and a delicacy for some enthusiasts. Another describes it as generally considered inedible because of its very bitter taste, and recommends against eating it, while noting it is not known to be dangerously poisonous. A third notes that it is good when it is not too bitter, but often it is. The genus Tylopilus is generally bitter-tasting.
No source read establishes a safe preparation for this species. The catalogue advises that the older identification needs modern species-level review, and that a food-use record does not settle safety. The page gives no edibility verdict.
Food use reported among the Ackawaio, with later adoption by some Patamona according to the catalogue; the further search did not confirm the Guyanese food use.
Animal blood is a perishable food material used fresh, coagulated, cooked, dried or processed into ingredients. Its uses range from grain-filled puddings to functional protein ingredients, each with distinct history and handling needs.
Boletellus ananas, the pineapple bolete, is a forest bolete of Guyana that one Patamona group eats and others avoid; a researcher reported mild stomach upset after eating it, so it is not a recommended edible.
Brazilian honeycomb polypore, Favolus brasiliensis, is a wood-growing fungus of tropical forests recorded as food in Brazil and Guyana. It has no standardized food-safety assessment.
Clavulina kunmudlutsa is a coral fungus of white-sand forest in the Pakaraima Mountains of Guyana. The Patamona people, who give it the local name kunmudlutse, eat it; its preparation is not recorded in the sources read.
A wood-rotting bracket fungus of Brazil and Guyana that Indigenous Amazonian communities eat as a staple. Its edibility is contested in some field guides, and no standardised food-safety assessment exists.
Pulutukwe is the Patamona name for Amanita perphaea, a wild Amanita of the Pakaraima Mountains of Guyana that the Patamona people value as food. Its identity is not established for other Amanitas.
A Rhizopus mould stage converts starch in cassava for the Wapishana drink parakari. The published abstracts name the mould and its role but not the full culture method.
