Gymnopilus Junonius Mushrooms - 11/7/14

I found these mushrooms the day after a huge storm, the third really big storm this year with some of the highest winds on record. Clumped around a stump by the parking bay at the top of the section, they’d been there for a few days when I saw them but most were still in good condition despite the massive winds and rain. Lola said she’d seen them at the start of the week, but they would have been much smaller then. By the time I saw them they were packed densely together like a miniature alpine village spreading up the side of the stump.

I took the photos quite quickly, this was less than a week after I’d had my appendix out so I didn’t feel like getting down on the ground or spending too long trying to get the right shot. I wished I’d gotten up earlier with the light coming from a lower angle, but I was glad it was overcast so there weren’t any harsh shadows.

After spending time researching what species it was I’ve decided that mushrooms are my new favourite thing. I’m not totally sure I’ve identified these correctly, but the websites below are pretty straightforward with the identifying features they list, as long as there is a picture that matches. The really interesting stuff is how mushrooms grow and work in the ecosystem to break down organic matter, in this case the tree stump that the mushrooms are growing on. The actual fungus, or mycelium is a network of filament-like hyphae that are growing into the stump, using enzymes to dissolve the wood which they consume. When two hyphae in the network connect they can form a knot from which a mushroom grows. So the mycelium in our stump must be made up of hundreds of hypha which are connecting to grow the mushrooms.

One of the things that I’m slightly confused about after the reading I’ve done is that it seems like the whole mycelium network is often referred to as though it’s a single organism, whereas it is composed of many individual hypha which (I think) are genetically distinct. That said, one the hyphae connect and send up mushrooms, the spores of which have the combined DNA, then they’re not so separate anymore. So I’m not sure if I’m reading things wrong, or just that fungi don’t work the same as animals and plants, which is why they have there own kingdom in the biological taxonomy.

Now that I’ve started learning about them I’ve started seeing more fungi around, so expect a few more posts about them!

Here are some good websites about mushrooms:

A kaka in a nikau tree - 18/4/14

A couple of days after cyclone Lusi had blown through this guy turned up in one of the nikau trees at the top of the section. Tui, B, Lola and Lupe saw him as they came to visit, so I grabbed my camera to take some photos. I’d just bought an old Tamron zoom lens which was the longest lens I had, although not particularly sharp when the aperture is opened wide which I needed to do, but the photos are ok. I ended up walking down the neighbours driveway to get a good angle to shoot from with the trees giving a good background. The kaka watched me a little but didn’t seem too concerned, much more interested in tearing into the nikau berries. He’d use his beak to help swing from flower to flower, then pick out a berry, transfer it to a claw to hold it while eating.

Apparently there is a small group of kaka who live at Onetangi now, but before that they were thought to stop over on the way from Little Barrier to the Waitakere Ranges. I’m not sure what he was doing at our place but maybe the storm had blown him off course and he was having a feed before continuing. I haven’t seen any other kaka since then, but I’ll keep my eyes open around the island and maybe see some more.
