This one was about 40mm in diameter, there were a few older specimens in the area that were around 50mm in diameter.

maybe they tend to get larger in a warmer climate than mine.. What’s the size of the one in this obs?

I must have been lucky as what I belive to be L. citrinum have always been very large fungi 80mm or bigger. with no clare tree assosiation.

No big difference in size

My sources say 2-5 cm for cepa, 2-6 cm for citrinum

Not likely

to be Scleroderma citrinum if Michael observation it what I think it is. S. citrinum is much too large a fungus. The one I have in mind is 30 to 50 mm dia found under leptospermum.

The host trees were exclusively Leptospermum scoparium, unfortunately I didn’t collect this but will next time I see it!

Why not Scleroderma citrinum?

Yellow colour, thick scales, a wide range of hosts, and it’s reported from New Zealand.
I don’t think it’s cepa which has a smoother surface (sometimes a yellow form, flavidus, is separated).

Scleroderma sp.

You dont mention tree assosiation but I suspect its tea tree. The most likely name for this is Scleroderma cepa. Personal I have never liked this name but it comes from the experts at Landcare!

then there will be more layers. Probably there even though you didn’t notice them. The first layer leaves those patches on the peridium that are visible here, similar to the volval patches on top of an Amanita. The second layer is the thicker, in most Scleroderma several mm thick to over a cm in some cases; the final layer is a relatively thin membrane covering the gleba. This interior membrance can change color when sliced, which is why a detailed photo is important.

I know it’s a lot of work. But it is important.

Geaster and Geastrum also have have some of these features.

Southern Hemisphere fungi are brand new to many of us. That’s why they are so fascinating!

no collection was made although I did cut one in half in the field, the peridium consisted of a single layer and in context was white, the mature gleba was cinnamon brown and consisted of a single chamber, the fruit body was connected to the substrate by quite thick pale yellow rhizomorphs.
If I find this again and there’s not much in the way of agarics to collect I’ll collect it and make a new observation!

Please cut in half

through the base and add photo. There are features of the peridium which can only be seen when sliced through.
