Aleurodiscus vitellinus

Loading ratings…

Aleurodiscus vitellinus, the yellow disc fungus, is a wood-growing fungus of the Nothofagus forests of Patagonia recorded as a regional food; its safety and local species identity are not established.

Two yellow-orange shell-shaped fungi grow on a grey twig, with two cut halves resting beside it on a warm ivory surface.

What it is

Aleurodiscus vitellinus is a wood-growing fungus of the Nothofagus forests of the Patagonian Andes, in Argentina and Chile. It is known in English as the yellow disc fungus, a name the catalogue records. It grows on wood.

It is one of several native fungi that the Patagonian food literature groups with other forest mushrooms. The catalogue treats it as a food fungus on the strength of a regional consumption record, not as a species with a settled place in the kitchen.

Where it is recorded

The regional record places the fungus in Patagonia, which the catalogue gives as Argentina and or Chile. The catalogue records the ecology as Nothofagus forest wood. Nothofagus, the southern beech, is the group of trees under which the record places it.

The Patagonian studies of wild edible mushrooms are mostly laboratory and nutritional work with a small number of local collections. Consumption is described as local, and the catalogue gives no figure for how much of the fungus is gathered or sold.

Food use

The catalogue describes the fungus as a regional consumption record that has been studied as a food fungus. The Foods study of wild edible mushrooms from native Nothofagus forest reports it among the species with consumption records, alongside its nutritional composition.

The sources reviewed do not give a preparation for this fungus. This page does not describe how it is cooked, dried or stored, and it does not give a season or quantity.

Identification and safety

The catalogue states that the food-use record is not a comprehensive toxicity evaluation and that the local species concept needs verifying. The sources reviewed give no safety data for this species, and they do not establish that it is safe to eat in any quantity.

This page is not an identification guide. Wood-growing crust-like fungi are easily confused, and a specimen should not be picked or eaten on the basis of this page.
