Observation 65245: Boletellus emodensis (Berk.) Singer
When: 2011-03-26
(17.38303° 145.39389° )
No herbarium specimen

Notes: Growing from base of (bloodwood?) tree in Eucalypt woodland, approximately 940m above sea level.

I’m not confident of my identification from Fuhrer, however an article in wikipedia stated that “the cap may crack in older specimens, and reveal the yellow flesh beneath”, which seemed to exactly describe my speciman (http://en.wikipedia.org/wiki/Boletellus_obscurecoccineus).

I queried a volunteer ‘expert’ from an Australian fungi group and he suggested that Boletellus emodensis was the preferred identification. I can see the merit in that suggestion, but Fuhrer suggests B. Emodensis shows ‘ground red’ between the cracks in the cap; my speciman was definitely yellow, so perhaps B. obscurecoccineus is still possible?

Not in the fraternus group

But it is B. emodensis as I have seen it in Queensland. The colors look right but it is drying up in situ it appears. Note the fine squamulues at the edge of cap in the middle image. Also, note that the stipe is red but that color is fading. B. ananas probably doesn’t occur in Australia, but we’re checking on that, and B. ananiceps doesn’t have a red stipe and pileus scales are different. See Observation 20482 for B. emodensis, Observation 20565 for B. dissiliens, and Observation 44512 for B. ananiceps. See article in the Fungimap Newsletter 42 for developing a concept toward B. ananiceps.

Thanks Danny – the other link no longer works – it migrated to B. ananas vs B. emodensis etc.

Sorry for my slow response on this observation.

Might this fit within the B. fraternus group?

Halling’s Boletellus page (http://www.nybg.org/...) says of the pileus of B. emodensis

Finely squamulose deep rhubarb or strawberry red

Which doesn’t apply here unless this clearly older specimen began with richer cap coloration. All images/descriptions of B. obscurecoccineus I can find speak to the requisite presence of similarly vibrant red and, in this case, smooth cap surface in that species. Yours is decidedly paler (and definitely not smooth), though it’s age could be hiding key characteristics of its youth.

Given what I know following this impromptu crash course in Boletellus, I would say you have either B. ananas or B. ananiceps, or an old and description-defying B. emodensis.
