Mushrooms
Trogia infundibuliformis
Trogia infundibuliformis is a thin, translucent forest mushroom of Central Africa recorded as eaten in Tshopo, DR Congo; it is easily confused with the poisonous Trogia venenata, so identification matters.
Overview
Trogia infundibuliformis is a small forest mushroom of the family Marasmiaceae, which grows on dead wood and leaf litter in the warm, wet forests of Central Africa. Its fruiting body is thin, tough and translucent, so it looks more fragile than many forest mushrooms. The catalogue records it as a forest saprotroph with a wild context, and as a locally eaten species.
Distribution
The species is recorded across the Paleotropics, with records in the DR Congo, Gabon, Malawi and Uganda. In the Republic of the Congo, a field poster lists it among the edible species of the north of the country under a local name. The catalogue records a food use in Tshopo province, in the Democratic Republic of the Congo.
Food use
The Tshopo record comes from voucher-backed interviews, in which the mushroom was reported as locally consumed. The catalogue states that species-specific preparation was not established. The sources reviewed do not give a cooking method, a dish, a quantity or a season for this species.
Because Trogia has more than one species with different records, a food record for one name cannot be carried over to all records under that name. The catalogue asks that broad historical name concepts be reviewed before they are used.
Look-alikes and safety
The catalogue warns not to confuse this species with the poisonous Trogia venenata. It also states that the Tshopo interview record does not establish the toxicity of every record of T. infundibuliformis, and that the record is an ethnomycological record and not an independent toxicological assessment.
This page gives no identification and no edibility verdict. A thin translucent forest mushroom should be identified by an expert before anyone eats it, and a local food record does not make a specimen safe.
Open points
The sources reviewed do not give a preparation, a chemical or toxicity test, or a full list of the Tshopo species. The species tables of the Tshopo studies would show whether T. infundibuliformis is among the species recorded there.
