Lentinus berteroi

Loading ratings…

Lentinus berteroi is a sawgill mushroom of the tropical Americas, recorded as food in the Colombian catalogue and studied for cultivation in Brazil; a Brazilian food record for this species was not confirmed.

Two whole shaggy mushrooms and one lengthwise half with pale flesh and visible gills rest on a warm ivory surface.

What it is

Lentinus berteroi is a sawgill, a wood-decaying gilled fungus in the genus Lentinus. Its relative Lentinus crinitus is eaten by Yanomami and other Amazonian groups. Sawgills are recognized by the sawtooth edge of their gills, a feature that separates them from many other gilled mushrooms.

The name is not settled. A Brazilian study treats the Lentinus berteroi complex as a group of species rather than a single species, so records under this name may cover more than one organism.

Food use

The Catalogue of Fungi of Colombia lists the species as used for food and gives South America and North America as its range. The Colombian entry cites no Brazilian source.

The supplied catalogue records a Brazilian food-use entry for this species. A search for a Brazilian eating record specific to L. berteroi did not confirm it; the Brazilian food-use reports found concern the related L. crinitus. Until a Brazilian record for L. berteroi is checked against its original source, the Brazilian food use should be read as unconfirmed.

Cultivation research

A Brazilian cultivation study used isolate CCIBt3009 of the L. berteroi complex. It grew faster on rice straw than on eucalyptus sawdust, but formed fruiting bodies only on the eucalyptus sawdust substrate. That result points to cultivation potential rather than to documented eating.

Safety and identification

The catalogue states that documented occurrence and consumption do not establish a standardized food-safety assessment. Sawgills are not easy to separate from one another by eye, and the complex is not resolved. A wild specimen should not be eaten on the strength of this page.
