Tapinella panuoides

Naming the fungus

Tapinella panuoides (Batsch) E.-J. Gilbert is a gilled fungus. It was formerly known as Paxillus panuoides, and that name still appears in older books and in some databases. It is also called oyster rollrim. The catalogue keeps the name Tapinella panuoides and records Paxillus panuoides as a synonym.

The species is easy to confuse with Tapinella corrugata, which is also known as Paxillus corrugatus. A French field source also warns of confusion with Phyllotopsis nidulans, especially in young specimens. The lookalikes matter because the edibility records below depend on which fungus a collector actually had.

Where and how it grows

A French source describes it as growing on rotting conifer wood and as very rare on hardwoods. It is a decomposer of dead wood rather than a soil fungus, so it is found on stumps, logs and buried wood. The catalogue records the ecology as forest saprotroph, and supply as wild.

Searches of distribution databases turned up no African or Congolese record for this species. The Congolese record in the catalogue is therefore a single regional source, and it should be read on its own terms.

Food records and the conflict

The Tshopo record comes from voucher-backed interviews in Democratic Republic of the Congo, in which the fungus is recorded as locally eaten. The catalogue notes that the species-specific preparation was not established. The catalogue also records that other regional references regard the species as inedible or of no culinary value. Its safety status is therefore marked as a conflict for research only.

A North American description also gives the edibility as unknown and says the taste is not distinctive. A Wikipedia source cites a field guide that covers both edible and inedible fungi, but the sources reviewed here do not show its verdict on this species. Taken together, the sources do not support a food claim.

Safety

Do not eat this fungus on the basis of this page. The catalogue says to exclude it from recommended-food lists until the record has been reviewed. Edibility depends on correct identification, and the lookalikes named above make field identification unreliable without a specialist.

A Congolese record of local eating does not establish that the fungus is safe for other people or other places. Eating a wild mushroom that other references call inedible is a risk that the sources do not resolve.

What is still unknown

The record does not say which form was eaten, how it was cooked, how often it was eaten, or whether it was gathered from conifer or hardwood wood. A specialist review with voucher material from the Tshopo record, and a check of the other regional references, are the next research steps.
