General Description:
“Pileus nearly flat when rather young, usually becoming nearly hemispheric when older. Color at first light-brownish-yellow, usually brighter yellow toward margin, and becoming bright- yellow at maturity all over, and then often paler in the central part. Glabrous and somewhat moist to the touch, rather bright and shining. Usually 4 to 6 inches in diameter. Flesh always white until decay sets in. Tubes very small, white, and stuffed, then yellow, becoming rusty-yellow with age. Stem pure-white without and within at first, slightly reticulate, then later the top of the stem for about an inch or more becomes bright-yellow and this color extends gradually downward, without and within, as the plant grows older and finally the whole stem may become bright-yellow. The stem is solid, large, and enlarged toward the base."

— Prof. H.L. Wells, the collector/discoverer of B. gertrudiae in a letter to Prof. W.A. Murrill, editor of Mycologia (see Ref. 1)


Diagnostic Description:

Bright yellow cap and yellow pores at maturity; white, glabrous to slightly reticulate stipe, yellowing from apex down to ~1/4 and sometimes all the way to base at maturity


Distribution:

Originally described from Old Lyme, CT, this taxon has been found in New England and as far south as North Carolina; western limits TBD.


Habitat:

Deciduous woods; likely to be mycorrhizal with oak and beech.


Look Alikes:

1) Boletus nobilis in the sense of contemporary authors. Conspecificity between the two taxa cannot be excluded based on sequencing data of pertinent collections.
2) Boletus insuetus A.H. Sm. & Thiers
3) Boletus chippewaensis A.H. Sm. & Thiers


Uses:

Edibility reported as unknown (Ref. 3), but probably edible, as it’s a member of Boletus sect. Boletus.
