Observation 192181: Piptoporus australiensis (Wakef.) G. Cunn.
When: 2014-12-03

Notes: Unusual bracket fungi found on dead stump. Orange powder all over top and bottom of fungi. It was easily removed from its habit. The specimen was soft to touch, little or no aroma and the top part of the fungi I believe is part of the original growth, and not a new fungi commencing to grow atop the original.
The fungi was fresh and in excellent condition. I visit this area once a week and it was not evident 7 days ago.
Single specimen the only find in this total area. Local conditions were dry with light overnight rainfall. Eucalypt forest. Did not notice any insect damage. Fungi was approximately 8-9 cm across widest part of the face.

Thankyou for the info you kindly provided. I have copied/pasted into my Fungi notebook. Appreciated you expert advice. I do have KOH and I think I will try and get some hydrogen peroxide./ We used to be able to get it some years ago so I will check.

Looks like P. australiensis

The curry odor should clinch the ID.

I like the common name, Curry Punk.

do you have KOH (potassium hydroxide)?
it will certainly help a great deal if you do.
pull out a tiny bit of the pore surface w/ tweezers and place on a slide.
drop some KOH and the material and then soak up with a paper towel or tissue.
if you have any dye, then drop some dye (congo red, cotton blue) on the specimen and soak up excess w/ a paper towel, leaving just the specimen on the slide.
then drop some H2O on the specimen and once again, soak up the excess with a paper towel.
finally, add another drop of KOH and then place the cover slip.
use a pencil eraser to “crush” the material under the cover slip.
you will notice the specimen break apart under the slip depending on the amount of pressure you use.
clean the excess KOH (that flows from under the cover slip) w/ a paper towel and view.
this should help you out a great deal.
the less material you use, the better the result (in most cases).

if you do not have KOH, you can try hydrogen peroxide or 75% ETOH.
also, if you let me know, i can send you some KOH flakes if you can not get your hands on any.

cool observation.
i think the scent and habitat, definitely point towards Piptoporus australiensis as suggested.

I remembered Debbie mentioning about the “Hundred Chop” way back and so did this and was able to get some spore images @ 100 mag.(in Melzers solution)
I also can say that after I cut the fungi I can smell a strong aroma like curry.
I have had a comment from Heino and he suggested if it had a curry smell it could be Piptoporus australiensis (Curry punk)? Maybe this is what I have.

It is difficult to discern anything from your micrographs. It may be helpful to lead us into your highest magnification with shots taken of each of the preceding magnifications. That way we know what we’re seeing.

I would venture to guess this is immature, which really only leaves us with hyphal types as a diagnostic character (monomitic, dimitic, trimitic, etc.), though even these may not be fully developed. Who knows, maybe you find some spores or cystidia. Either will need to be seen in abundance to be sure that they are a: spores/cystidia, and b: belong to the specimen in question. One little thing floating around in your mount is not enough.

Polyporales sensu lato (192181)

Micrographs added + cut view. Micrographs taken form inner cut section of fungi.(Melzers X 40)

Will do, have saved the specimen and will try and do some micrographs today.
Thanks for the comment. I have found something similar wayback. Will check my archives.

Cool find. Did you cut it open?
