Description

Genus: Lanmaoa

Species: fallax (nom. prov.)

Common Name: No-smell Pallidorosea

Tells: Stout red-and-yellow. White mycelium. Cap color varies enormously, from rose pink, to brick red, or even deep mahogany, fading toward brown w/age. Yellow pores and stem skin often bruise blue.

Other Information: Little to no bouillon smell, but may hint of a sweet flavor. The pores age darker as the olive spores stain the tubes. Stem flesh is lemon yellow at the bottom, getting paler higher up and becoming almost white in the cap. Flesh blues erratically (or not). The mycelium is white rather than pale yellow. More of a normal bolete texture than the “supermarket cheese” denseness of pallidorosea. Note that the geographic filters show only confirmed finds, but the species seems to have an extremely wide range that probably includes most of North America from the eastern Rocky Mountains east to the Atlantic.

SUMMING UP: This maddeningly inconsistent species is that one in the middle that fits right between your concept of either L. pallidorosea or L. pseudosensibilis, is the most morphologically variable of the three, and apparently the most widely spread. The gestalt really is different if you’ve met a lot of Lanmaoas, and the DNA evidence is irrefutable, but users should expect their field IDs to be frustrating at best.

Science Notes: Professor Colin Domnauer has established the separate existence of this species has been established by both whole genome testing and a distinctive ITS gene, so there is no doubt at that level. For DNA tested examples see MO 522445MO 523668, MO 247518, MO 327563, MO 320102, MO 333824, and MO 247518. “Fallax” comes from the latin word for “deceptive,” referring to the variability of how this species presents itselve in the wild.

Edibility: Edible.
