Photographing New Zealand's native Blue Mushroom

It is autumn here in New Zealand at the moment - and autumn for many photographers ushers in the start of something special - fungi season.

I'm a relative newcomer to fungi photography, having really only gotten interested at the tail end of last season. But I've got the bug - hard - and have been waiting patiently (or not so patiently as the case may be) for the new crop to start appearing. 

We have had a very hot, dry, summer on the West Coast of New Zealand - and it's taken a while for the rains to come. But come they have. And with it, comes the appearance of one of New Zealand's most iconic native mushrooms - the Blue Pinkgill.

Two weeks earlier (as I write this), my wife and I had taken a drive to Lake Kaniere. My wife has some friends coming from Australia to visit, and we were scouting locations to take them to. I suggested we go to Sunny Bight, to a small bushwalk there, and see if it was somewhere worth taking them to. It had been raining earlier in the week - although not a lot - so I really wasn't expecting much.

On the small walk at the Sunny Bight picnic area, we came across a little patch of Calocera viscoa, or Yellow Staghorn - a coral fungi that I had never seen before. I was very excited by this find and took a couple of quick snaps. But I didn't have my macro gear with me, so made a mental 'note-to-self' to return as soon as I could with my macro setup.

Since the Sunny Bight picnic area walk is just a short 10 minute loop through native bush, we decided to explore further. Just past the picnic area is a dirt road that leads to the Lake Kaniere Walk - a 7hr return tramp that I had never taken a look at. We walked up the road, again surrounded by native bush, until we got to the carpark that is located at the start of the trail. Since neither of us were keen on a 7hr tramp, we turned around to head back to the picnic area. Just a few metres back along the road, a flash of brilliant blue caught me eye. And then another. And another! I stopped my wife and called her over, and together we discovered a a forest floor blooming with Entoloma hochstetteri - the native Blue Mushroom. 

I was so excited - never having seen one 'in the flesh' before. We spent the rest of the afternoon exploring, finding more and taking photos (mostly just snapshots), completely enthralled by this beautiful little fungi. It is the most beautiful, vibrant, almost iridescent blue. I was delighted to have discovered them, and couldn't wait to come back to photograph them properly.

Unfortunately, that wouldn't be until two weeks later!. Fortunately, they were still there - if not in even greater abundance than last time. Again I was so excited and set about making the most of my afternoon.

With such a vast array of subjects, I was somewhat spoilt for choice. Believe me, I'm not complaining. But it did mean I could be a bit more picky about my subjects. Normally I come across one or two mushrooms and get to choose between the two. But the blue fungi were everywhere I looked! So much so that I needed to be careful where I walked (and I was - no mushrooms were harmed in the making of these photos).  I therefore started looking for either the unusual - or the most photogenic and prisitne examples that I could find. 

Mostly the blue mushrooms grow tall and straight. But the one exception I found was of the image above - appropriately titled 'Twisted'. As soon as I saw it I knew I had to take a photo of it - as unusual as it was amongst all the other upright specimens.

Entoloma hochstetteri is thought to engage in mycorrhizal relationships with Nothofagus and Podocarpus tree species. Mycorrhizas are beneficial fungi growing in association with plant roots, and exist by taking sugars from plants 'in exchange' for moisture and nutrients gathered from the soil by the fungal strands. The mycorrhizas greatly increase the absorptive area of a plant, acting as extensions to the root system. The native Kahikatea tree (a Podocarpus tree species) grows all around Lake Kaniere, providing a perfect breeding ground for the small blue mushroom species. Find a Nothofagus or Podocarpus tree species in New Zealand, and you are likely to find Entoloma hochstetteri at a certain time of the year.

Photographing fungi is a bit like bird-watching - in that when you find and photograph a particular species you tend to tick it of your list. I wanted to find the New Zealand Blue, as occasionally it can be somewhat elusive. But not this year. This year there seems to have been an abundance at the start of the season - although that's the other thing about fungi. They seem to go as quickly as they come. Only to be replaced by another species as the season progresses.

I don't know what I'll find the next time I'm out on a fungi forage - but that's also a large part of the fun. But whatever the season brings, I'm thrilled that I've already got Entoloma hochstetteri in the bag!
