The impact of record rainfall: 2 Fungi

This is the second post about the side effects of the recent rain.  In the case of fungi, I suspect that the relevant indicator is that we have received some rain (and I really only record ~1+mm) on 17 of the 29 days of February.  Cutting to the chase as we looked around the property today there were more fungal fruiting bodies - in both numbers and diversity than we have ever seen before.  It was like a rain forest without the trees!

I am putting the images up now, in the hope that I can update IDs etc later.

What really kicked this post off was Frances noticing a lot of brown lumps in the top paddock while we were walking the small dog this morning.  These turned out to be a heap of fungi.
On getting closer they were clearly agarics of some form.
Then we started to see large white fungi (lots of them) with 'drippy bits' - a partial veil.  As Denis has commented below, this is Macrolepiota dolichaula- which I have included before but didn't have the name in whatever drives my fingers over the keyboard.

I think this next image is a very young version of this species.
One of the commonest fungi around the place is Omphalina chromacea.  This next image shows well the algae with which it associates.  (This is a zoomed image - they are not huge!)
Also common is Marasmius oreades - the Fairy-ring champignon.  The first image shows a clump of them, while the second shows the spore print after sacrificing one of them in the cause of science (they are not exactly endangered).

A long-dead eucalypt was graced with a Gymnophilus junonius art the base (sorry about the mini-brambles).
 We now show a couple of images of a bolete.  They started off looking like this..
 .. but as they age degenerate to this.
Other boletes, possibly Boletus barragensis, were found a couple of days later.  The third image shows the bluish stain resulting from my bruising part of the cap.

Dodging about a bit, we - specifically Frances - found these two Earthstars (Geastrum sp).  A couple of days later there were 10s of these in the same spot.
Earthstars are closely related to puffballs, and on later visits to the top paddock I found a lot of small yellow puffballs growing.  I have no idea of the specific identity of these!   Note the visiting ant!

Now to a few complete unknowns.

The main point of the last image is that the gills look very like a Field mushroom.  We have a lot of them and eat them with great enjoyment.  The top does not look like a field mushroom, so it isn't getting eaten.  The idea of spending 4 days dying of liver failure does not appeal.

The next day (1 March) I found several of these fungi growing near our house dam.  I am sure I will be able to find a name soon.
The rain has continued and on 4 March we found this nice fungus possibly Ramariopsis crocea growing on the ground in a Joycea/Eucalyptus area.  The images gradually close in.
Here is a spore print from this coral fungus:
Nearby, on the bark of a Eucalypt I found a bracket fungus.  Due to the wonders of computing I have combined both the over and under sides in a single image.
From a subsequent scouring of Fuhrer I suspect this is Hexagonia sp.- possibly H. tenuis.

Hi Martin.
Lovely assortment of Fungi.
The tall white ones are almost certainly Macrolepiota dolichaula (but you probably knew that).
Love the little slimy yellow one with the semi-transparent cap. (Your first of the odd ones). I have no idea, however.
The Omphalina chromacea up here are having a record season.

Thanks Denis.

I did know that name, in a visceral sense. Unfortunately the words hadn't risen from the sacral region to cranial region when I hurriedly compiled that post. I will now fix.
