Observation 129316: Boletellus deceptivus Hallling & Fechner
When: 2013-02-14

Notes: The oxidation reactions (cyanescence and brownish orange) are not visible here. Eucalyptus species were in the majority here. Possibly Allocasuarina. The hymenophore is also immediately cyanescent.

Note that the stipe is nearly white (sometimes red zone at apex), and rarely with a pinkish flush (left hand basidiome). The pileus scales are almost as fine as B. emodensis and are never as coarse as in B. ananas.

Recognized by sight: This is a member of the type section of the genus (sect. Boletellus) allied to B. ananas (type species), B. ananiceps, B. dissiliens, & B. emodensis. The taxon imaged has yellow, immediately cyanescent flesh in the pileus, white flesh in the stipe that slowly oxidizes to a brownish orange. Boletellus emodensis is cyanescent in the stipe to the base but will slowly oxidize to the brownish orange color at the very base; the brownish orange color is slower to appear than the cyanescence.
