Blushing false truffle

What the fungus is

Rhizopogon roseolus is a false truffle, a fungus that fruits underground or at the soil surface and is not a true Tuber truffle. It forms partnerships with the roots of pine trees and is recorded in pine woods in Europe and North America.

The name is not settled. Texas Mushrooms lists Rhizopogon rubescens among its synonyms, and some older sources use that name. The catalogue records the name as a research label, and it notes that the maturity stage and the taxonomic concept both need checking.

Food use in Japan

In Japan the fungus is known as shoro, and Wikipedia reports that it is considered a delicacy there. A commercial seller of Japanese produce states that only young shoro are considered edible, and describes young specimens as having white, firm flesh with a faint pine-like aroma and a mild, slightly sweet flavour.

These are the only sources on this page that describe eating the fungus. The seller's page is a commercial description, so the eating window it gives should be read as the seller's claim, not an independent assessment.

Food use in Europe

The supplied catalogue records a regional use of immature false truffles in Europe, and places it among the food-use records with processing, stage or identification conditions. The catalogue does not give a preparation method, a quantity or a dish for the European record, and this page does not add one.

Habitat and season

In Texas the species has been found with loblolly pine and shortleaf pine. Texas Mushrooms reports that it typically fruits from late summer to early autumn. Pine association and season vary with place, and this page does not extend the Texas record to other regions.

Identification and safety

Because the catalogue marks the food use as conditional on stage and on identification, a young fruiting body should be checked closely against the mature form and against other false truffles before it is eaten. The sources reviewed here describe no safe quantity and no storage time.

Confirm any identification with an experienced local forager or a mycologist before eating a wild fungus. This page does not give an identification or an edibility verdict for Rhizopogon roseolus.
