Likely cool weather too, down under.

I’d guess you have at least 2 weeks, maybe longer before there’s a danger of losing it. But I don’t know how a soft polypore like this would react to a freeze. Something to consider…

I noticed it last week for the first time, new hunting grounds though so no idea how long it had been there, it still seems quite fresh and in good condition, we have had a heck of a lot of rain here lately also.

It seems free of bugs and damage, and doesn’t appear to have dried out since my first observation of it.

collect both. It’s best to have as much variety in a voucher collection as possible. And while there’s always the possibility this is the only fruiting of it anywhere, you should see more fruitings in another year or so.

After collecting, slice the sporocarps about 1/2 inch thick (1.25 cm) to speed dehydration. Dry in well-ventilated area, or with a small fan providing warm air over the collection. Let dry at least 3 days or more, until collection is as close to bone-dry as possible. Even residual moisture can make a fleshy polypore worthless if not bone-dry.

As for now long it should last: don’t know. Similar fungus, Polyporus squamosus usually lasts for several weeks, providing this is a relatively fresh obs. How long have you noticed it already?

I’d best go collect it then.

Thanks again for the help Daniel, this may seem like a silly question but I just don’t know, what is the lifespan for something like this?

I can’t get back there during the day for another week, I can however do a midnight torchlight mission if the specimen is likely to degrade too much in that time period.

Also there are two of them on the same tree, is it worth grabbing both, or will one be sufficient?



Likely not P. decurrens, then.

Arora states P. decurrens “Cap 4-14 cm broad…” which would seem to rule out a cap some 30cm broad.

About the only thing we have in that size range is P. squamosus, which is typically covered with soft scales. I don’t see that here. The flesh seems too thick as well.

You may have a species novum here. Need to take a voucher collection, detail as much about the fungus as possible, and send somewhere for long-term storage. I would think an herbarius in Australia would be appropriate.

Need more photos, too, including a ruler so that size can be confirmed.

Cheers for the help Daniel!

It was growing on Eucalypt, the entire body was soft and squishy both pileus and the pore surface. Reasonably low down on the tree probably about chest hight for an average sized person.

I checked on it again today to see if I could gather any more information, the only other thing I noticed was that the white colouring appeared to be spore deposit as it rubbed off quite easily and left a tan coloured pore surface underneath.

Overall size was roughly 300mm across. I am not sure about the amount of pores/mm, will update with as close a guesstamite as I can muster.

I have yet start looking into this one properly myself, I got too distracted with Dermocybes.

Need more data.

What is this growing on? What is the width, approximately. Was it soft or bone hard? I know these are a lot of questions, Tex. But what is found in my area (West coast, U.S.A.) is not necessarily found in Australia. Approximate number of spores per mm would also be helpful.
