Observation 196605: Tylopilus P. Karst.

Small light brown Capped fungi with partial bright yellow stipe. No bruising when cut. Area, Eucalyptus and semi-rainforest. Soil damp. Spore print light,light brown to dirty white. This was not the usual spore print showing the gill outlines but rather a smudged deposit on the paper. Light, light brown was probably a bad choice of colour description. The best I can do is dirty off white. No particular identifying aspects or aroma.

to see what you find and contribute. It has always helped me out with extended distributions, new stuff, etc.
I’m hoping to get on the austral ‘ballouioids’ later this boreal spring/summer. Some colleagues from China have graciously contributed data for grist in the mill. Stay tuned, and thanks again.


Hi Roy, and thank you so much for providing the help we so much were in need of.
Kind Regards kk. (Some dried specimens available if you wish to nominate.)Thanks to Roy and Debbie for the Links. I have archived your link Roy. Wow sooo interesting. What would we do without the internet for knowledge. Gggeee.

here’s the direct link to that page …

Ballouioid group

My apology for not visiting MO recently. This particular observation falls under the category of the Tylopilus balloui consortium as I have seen them in Australia. Cap colors range from white, gray, brown, yellow, orange, pink, red, olive green. Same with the stipe (but not olive green or pink yet). The tubes can be quite ordinary in shape as seen in Ian’s observation here. There is, however, what I call a “favoloid” morphology for some; it even approaches a ‘gasteroid’ condition on occasion. Go here: http://sweetgum.nybg.org/boletineae/specadvsearch.php and search on Tylopilus balloui AND Australia. You should get 64 specimen records, mostly with images. I think I have posted some here on MO.
The only taxon, so far, of this group that has a name is a yellow viscid one from Western Australia, Rubinoboletus phaseolisporus. As the epithet implies, it has bean shaped spores, but it’s been placed in the wrong genus. Rubinoboletus is a synonym of Chalciporus – morphology and molecules back this up. BTW, one of the features holding the ballouioids together are the bean shaped spores (99% of the time). Cystidial features are a dead giveaway for Tylopilus. Todd Osmundson has molecular data to back it up.
Porphyrellus is not an alternative name for Tylopilus. Porphyrellus hangs by itself (along with other dark spored boletes) in every recent molecular analysis I’ve seen.

Thanks for the kind words!

great minds …

I will send Roy a heads-up about these recent posts by Ian. So useful to have a “local” expert on OZ boletes, altho I am sure that Roy would modestly say that he is no expert, merely a student. Still, he has seen and IDed more of these than most.

This white pored entity reminds me of the other OZ bolete that you recently posted, Ian … perhaps the hymenium undergoes a color change over time? They both seem to have that bright yellow coating on their stipes.

Keep up the good work, Ian. It always feels a bit like Xmas when I see your spectacular mushroom photos.

We need Roy Halling for this and other bolete posts by Ian. I thought he frequented that part of the island continent in his quest for arcane boletes. :)

Can we at least try to ID to subfamily (sensu Wu et al.) or maybe a genus? How about going with what we know from the pix, like the color of the hymenophore? Tylopilus, anyone? :) Ian, what about the spore print?

Thanks Ian and Debbie!

I should have recognized sap and cap. Somehow it just didn’t make sense.

As Debbie rightly quoted. Cap

Just my terrible typing abilities. mmmmrrrrrrr kk

cap not sap.

Are you saying this fungus had “light brown sap(ped)”? A Boletaceae with latex or exudate would be quite unusual…
