Description: It is characterized by a robust and rather inconspicuous appearance, featuring a whitish to cream-colored cap, often with yellowish tones and a smooth or slightly sticky surface in moist conditions. It can reach considerable size, becoming flatter as it matures. The stem is thick, white, and solid, with a ring and a well-developed volva at the base, typical of the genus. The gills are white, free, and crowded, while the flesh is also white but emits a strong and unpleasant odor, a key feature behind its name. The species corresponds to Amanita foetens.

Geographic distribution: It is mainly distributed in temperate regions of the Northern Hemisphere, with records in Europe and parts of Asia. Its occurrence may be localized and less frequent than other members of the genus, making it harder to observe in some areas. It is rarely found outside its natural range due to its dependence on specific host trees.

Habitat: It inhabits deciduous and mixed forests, forming symbiotic relationships with trees through mycorrhizae. It prefers organic-rich, moist, and well-drained soils, typically appearing during autumn. It is more common in relatively undisturbed areas where soil and vegetation conditions remain stable.

Feeding: Like other species in the genus, it has a mycorrhizal nutritional strategy, forming mutualistic associations with plant roots. Through this relationship, the fungus enhances the uptake of water and minerals, while receiving organic compounds from the host. This exchange plays a key role in maintaining forest ecosystem balance and productivity.

Toxicity: It is considered a potentially toxic or inedible species, likely containing irritant compounds that are not fully characterized. Ingestion may cause gastrointestinal distress, including nausea, vomiting, and abdominal discomfort. Its strong unpleasant odor may serve as a natural warning signal. Due to the toxicological uncertainty and its relation to other dangerous species within the genus, consumption should be strictly avoided.

Reproduction: It reproduces via spores, which are released from the gills and dispersed by wind. Under suitable conditions, they germinate and form new mycelial networks. The formation of fruiting bodies is triggered by complex environmental signals, especially during favorable seasons such as autumn.

Conservation status: There is insufficient global data to precisely assess its conservation status, but it is generally not considered widely threatened. However, it may be locally affected by forest habitat disturbance and changes in tree community composition.
