The colours listed for that species are maroon or Hessian Brown, Claret Brown or near Liver Brown, these are rather dry and would show that darker colour if they were more hydrated, I would say the colour here is a good match for Hessian brown.
I examined the microscopic characters and there are only two species that this could be, T. rufofulva and T. serrulata, the micro characters are a perfect match for the former species and T. serrulata is not known from NZ.
I guess it could be an undescribed species but I’m pretty sure it’s T. rufofulva.

My hat is off to you guys that thought Tubaria or similar brown spored genera…

The new photos have me convinced, of course. Thanks for the update!

it looks like a Tubaria… it isn’t T. rufofulva; which is deep burgundy-red when young.

Douglas had the genus right although I was close with Pholiota as this species was previously thought to be in that genus, it’s Tubaria rufofulva.

Spore deposit, yellowish rust-brown, smooth, ellipsoid and lacking a germ pore, 7.5×5µm.
Pleurocystidia absent.
Cheilocystidia irregularly cylindrical with an obtuse and sometimes swollen apex, 35-45×5-10µm.

Similar to a NA Tubaria sp.

This looks very similar to Tubaria confragosa found in North America. Yours is probably a different species, but here are some microscopic details: Spores of Tubaria are light yellow brown under the microscope, and they lack a germ pore. They are smooth and elliptical in shape. T. confragosa has spores 6.5-9 × 4-6 microns.

I have a hard time with this having a brown spore print. Can you collect one from the same spot, get some photos of the new collection, and get a photo of the spore print? I know that is a bit much to ask. But this just screams Armillaria.

why is the spore print brown if its a honey?

i agree that is looks identical to an Armillaria species, but the spore deposit is brown (Michael 1st comment)

maybe someone made a mistake?

Its Armillaria
By: Alan Rockefeller (Alan Rockefeller)

This is Armillaria due to the texture of the cap, texture of the stem, color of the stem and the appearance of the annulus.

Brown spore print…

So it has a brown spore print, is it light cinnamon brown or dark brown?

I didn’t collect this, I might go back tomorrow to collect the larger specimen to take a closer look!

This has a brown spore deposit, possibly Pholiota.
