Boletes - Fleshy texture, stems central (more-or-less)


 

The fungi in this sub-group produce fruitbodies that, until you look below the cap could be mistaken for mushrooms. However, instead of gills below the cap there are pores. In fungal field guides you will find these fungi referred to collectively as boletes. In boletes the cap is quite thick in relation to its diameter. In some boletes the flesh or pores may turn blue when damaged, in others there is no colour change and bolete identification keys ask about this.

 

In the following hints you see examples of useful identification features and a few of the more commonly seen genera in which at least some species (not necessarily all) show those features.

 

Hints

Cap over 30 cm in diameter: Phlebopus.

Very soft texture, like marshmallow: Fistulinella.

Red cap, yellow pores: Boletellus.

Growing near pine trees: Suillus.

Growing near birch trees: Leccinum.

Stem deeply pitted, somewhat honeycomb-like: Austroboletus.

For the Suillus suggestion to be a likely possibility there would probably need to be a Pinus tree nearby, I can't see any evidence of pine needles in the images. Suillus has a high host fidelity to trees in the Pinaceae none of these hosts are native to Australia. Suillus has also been reported from Quercus but there are no signs of oak leaves in the image. I can't make out the species of the trees in the maps image, though that might just be my eyes as computer screens have become hard to read.

No. There were a few silver birch street trees on the opposite side of the road, but they were removed 2 years ago. The fungus was beside a cultivated geranium, and just more than a meter away from a gum tree (E. viminalis).

Phlebopus doesn't stain blue. This appears to be one of many previously undescribed species of native bolete.
