Almond mushroom
The almond mushroom, Agaricus subrufescens, was cultivated in eastern North America in the 1800s, lost its market, and returned as a cultivated mushroom from Brazil, where it is grown under several names.

Pseudohydnum viridimontanum is a jelly-tooth fungus that grows on wood in the Atlantic Forest of Brazil. A 2024 ethnomycological record documents its use as food; no preparation, local name or safety assessment is established.

Pseudohydnum viridimontanum is the name used in the supplied catalogue, which records the common name green-mountain jelly-tooth fungus and the supply as unknown. It is recorded as a wood-growing fungus of the Atlantic Forest. The catalogue does not validate the name against current taxonomic authorities, so its accepted status is not resolved here.
The 2024 Brazilian edible-mushroom review notes that many of the species names it lists still need taxonomic study, and that sequencing has revealed misidentifications even for economically important species.
The 2024 review of wild edible mushrooms in Brazil cites an ethnomycological record of the use of Pseudohydnum viridimontanum by Coelho-Nascimento and colleagues, published in the same year. According to that record, the fungus is consumed. The review gives no local name, habitat detail, or preparation for it.
The review assigned the taxon its edibility status in a supplementary table that was not available when this entry was written, so the category it received is not recorded here.
No preparation or cooking method is recorded for this fungus in the sources read for this entry, so none is established here.
This entry is not an edibility verdict or an identification. The catalogue states that documented occurrence and consumption do not establish a standardized food-safety assessment. The review states that its edibility records must be read with caution because they include taxa that need further taxonomic investigation.
A consumption record in one country does not show that the fungus is safe to eat, or that a fungus collected elsewhere under the same name is the same organism. Wild mushrooms must be identified by a qualified expert before any use.
The Brazilian edible-mushroom review cites a 2024 ethnomycological record of its use in Brazil. The review gives no locality for that record.
