Observation 91148: Boletellus deceptivus Hallling & Fechner
When: 2012-03-28
(-28.0° 153.0° )
Herbarium specimen reported

Notes: I am posting this observation to augment my comments on Observation 91018 by Tex.

The pileus flesh is truly yellow, masked by the rapid cyanescence. A hint of the yellow can be seen in the image near the stipe apex. Also the stipe surface AND the stipe flesh is white with a slower brownish orange oxidation in the base.

Herbarium specimens in BRI & NY (REH9653).

I have seen this morphology only a few times in the past 6 years or so – in Queensland and northern NSW. The pileus scales are somewhat coarse, nearly flattened and are tan colored surrounded by red; the stipe is white and sometimes with a red zone at the apex. By the time a basidiome reaches this stage of development, the sterile marginal veil has usually disappeared. Under the light microscope, the spores have ribs marked with cross-striae.

More information can be found at Boletineae. Go to the Keys link, then Boletellus sect. Boletellus. Also, pursue the Taxonomy link. Thanks.
