More on Fly Agarics

In addition to the agarics I found close to home a friend mentioned that while on a run he had found huge numbers of them (and other fungi) in the Cork oak plantation in Canberra.  We arranged to meet near there for a follow up visit.  Let us start with an artistic shot.
There were indeed very large numbers of the fungi around.  The following shots show a linear colony (if that is an acceptable term in mycology) and a cluster.  Note the ground being almost totally covered with fallen cork-oak leaves.
As far as I could determine the disturbed ground around the lower cluster were due to the untidy table manners of White-winged Choughs that were browsing nearby.

I included this image as the white spore print is clearly visible where spores from the tallest fungus have fallen on the one below.

The next two images show the fungus and some of the leaves of oak regrowth.
My friend challenged me to estimate the number of agarics present in the area.  Measuring the length and breadth of the plantation on Google Earth I came up with an area of just over 8 hectares.  In the field there appeared to be about 3m between rows of trees and I decided to do some transects counting the number of fruiting bodies in each avenue (and the number of steps taken for each transect).  I was able (from the breath of the plantation on Google Earth) to estimate the length of my double step as about 1.8m.  Doing 5 transects my study area amounted to 2700 sq m and I counted 318 fruiting bodies.  Simple arithmetic came up with the astounding number of 9,500 fruiting bodies.  The number of bodies per square metre varied considerably between transects but even dividing the number by two still gives close to 5,000!

There were many many other fungi present.  I was hoping to see a Death Cap (which I have been told have been seen here in the past) but they did not appear.  This (which I cannot identify) was the commonest:

There were a few Boletes:
.....  and a few bracket fungi dealing with fallen cork oak branches.
I did identify some Omphalima chromacea (a Fungimap Target Species, which I have included in other pages) and Stereum hirsutum (also a Target Species.

Hello Martin,

What a fabulous place to go fungi hunting, thank you.

I've never seen Amanita muscaria in numbers anything like you've illustrated. Also, I've never seen such a great example of Stereum hirsutum - that's a real beauty.

Regards,
Gaye

Insects from pine trees

Image
This afternoon (13/1/2015) we were looking out of our sunroom and noticed a strange bit of mist.  On getting my binoculars on the case I found it to be a cloud of tens of thousand of insects.  They appeared with naked eye to be flying away, but with binoculars I thought they were circling. Here are some images In the second one it may be possible to see there are two streams coming from the top of each tree. There was a loud buzzing noise but that could just be several thousand wings. Earlier in the day Frances had been to some nearby willows and they were infested with many little black soft bodied insects.  Perhaps they shifted to the pines and were swarming? Help!! Any information welcome. A colleague, from Wamboin, had noticed a similat phenomenon, but involvng eucalypts rather than pines!  Here are the photos he took with his phone. I have consulted some expert friends.   Their responses were: I would have gone for chironomids. I rec...

A tour of the West (part 1)

Image
A friend from my time in the UN sent me some photos of her family trip along Route 66.  They did this is a large camperwagon rather than a Chevy Corvette (apparently the kids jacked up about being offered a trip in the trunk).  It seems to have been a very good trip for them and most interesting to see their photos.  It was also educational for me, as I found out the German for rocking chair (schaukelstuhl, since you ask). They did 7200 miles in 30 days - a pretty serious bit of distance. This made me think of the trips we did in 1981 when living in Denver.  Frances initiated that idea by getting a book about the National Parks of the West  and marking interesting places.  I then worked out a route on a Rand-McNally Road Atlas (GPS was unknown then  - as were iPhones, personal computers and the internet).  From memory, taking nearly the whole Summer school holidays we covered about 10,000 miles in 70 days.  Here, approximately,  are ...

Maslins beach rules

Image
Anyone who was in Adelaide in the 1970s will be having a good nudge nudge at that title.  However the beach is really nice even though it is the haunt (in Summer ) of naked people.  (As an aside one of the 'van park staff was talking to some other guests and commented that the sights on the beach in Summer were not at all exciting.)  In April it is the haunt of seniors, many of them exercising their dogs, and thus a far more attractive place. Getting to the beach was a walk of about 1km along roads, from our van.  The second half of this went past a rather daggy looking paddock with many formed ridges in it, as though it was irrigated, although a water sources wasn't evident.  The paddock got interesting towards the end as some green parrots appeared.  Thanks to Frances eye for detail we have subsequently identified these as Elegant Parrots: my first lifer for 2014.    The locale is indicated by the red lines in this mudmap: Here are the bird...
