Its not widely know that Australia has a handful of native and introduced morels (Morchella) species. I am fortunate to have found a yellow morel Probably a member of the Morchella esculenta cluster. I found them locally growing by a river under small leaf privet, ferns and rain forest regen, they fruit from sandy loam. I’ve found them two years in a row after a wet period in September or early October. Recently i have seen some photos of a similar species from a bit further north. I think its likely that the yellow morels are reasonably common in this part of the country.
Morels are one of the worlds most sought after gourmet mushroom. I was well pleased that my find has great taste and texture when cooked, in my opinion this rules out M. rufobrunnea as a possibility. We sent some away for DNA analysis but unfortunately we were unable to get a result. I am hopeful to find some more this season so I can try again. A quick search on the Atlas of living Australia yields over twenty records from Australia from the esculenta group. Some in southern Queensland, others further south in NSW and Victoria.
Omphalotus Nidiformis The ghost fungus
Ompahlotus Nidiformis is a common fungus fruiting from summer into winter in these parts. I’m doing this post for a couple of reasons, firstly this fungus is poisonous and i will talk more about this later, secondly its easy to confuse these guys with pleurotus species or oyster mushrooms, thirdly they glow in the dark and finally i have a shot of them glowing that I’m particularly pleased with so why not share it on the interweb, who knows maybe someone else will like it too!
The Ghost fungus grows in all kinds of habitats all up and down the east coast and all the way into South Australia. They form big flushes of fruit bodies that are hard to miss in the forest, they have a whole bunch of morphs and colour variations that at times can make them a challenge to ID. When i first became interested in edible fungi I started to find these and pick them, I would bring them home and try to convince myself they were oysters, on one occasion I did such a good job that I fried some up and ate a few bits. They tasted pretty good, later that night I felt a bit crook. I had a second look at them and found they were glowing ever so faintly. Thankfully I only ate a very small amount and did not need to spend the night ridding the porcelain bus.
Omphalotus Nidiformis Are wood decomposers, they are almost always found on dead trees or roots. They are a white rot fungus that can be found anywhere from coastal scrub to mountain rain forest, in pine plantations and eucalypt woodlands. For me a key to their ID is the way the gills attach to the stem and the stem itself which is smooth and woody, often tho not always darker coloured. Picking a mushroom and examining the stem is probably the best way to ID these guys. Another key feature is the darker spot of colour in the middle of the cap. the colour itself is changeable but the spot is present most of the time directly above where the stem attaches to the cap. Their spore print is white.

The Bioluminescence of these fungi is variable. Often in this area it is very faint and sometimes non existent. I generally find that it is a very dull glow tho I have read that it can be very bright in some specimens. Its best to look for the glow at night in a very dark place and the glow will improve as our eyes adjust to the dark and our night visions kicks in. An explanation for the bioluminescence can be found here. its become a bucket list item for Aussie fungi enthusiasts to get that classic night shot which can improve the dull glow. The results can be spectacular. Scout your location during the day then return at night to get the shot.

The biochemistry of this fungus is interesting. They contain some novel chemicals with anti tumor and antibiotic properties. The chemical itself is called Illudin and is present in a couple of different forms. As an isolated compound Illudin shows selective toxicity for leukemia and some other types of cancer cells. A drug containing Illudin is able to react with cancer DNA inside the cells. Currently called Irofluven it is in phase two clinical trials. However Illudin in its natural form is toxic and can lead to GI distress and vomiting, which can last for several hours after ingestion. Its not deadly.
Omphalotus Nidiformis has many faces

Australian Edible Mushrooms and Fungi
This Page will be a record of the edible Mushrooms and interesting fungi I find within about 100km of Coffs Harbour, NSW Australia. The coast has a subtropical climate with high rainfall while in the hinterland we have a plateau with mountains that reach up to 1500m with the odd snow fall in winter. the range of climate zones and micro climates along with the multitude of vegetation types makes this area a fascinating place for mushroom hunting. To date I have found over twenty varieties of edible fungi in the area.
In Australia the eating of foraged mushrooms is regarded as dangerous. This is the result of a lack of a foraging culture, the loss of indigenous knowledge of fungi and fear based on misinformation.
Identifying mushrooms is a learned skill, anyone who is prepared to spend the time can become competent and therefor safe. Without the required skills and knowledge mushroom foraging is risky and can result in misadventure, in fact the risks are real. Fortunately most mushrooms are benign and some are delicious. There is no standard test for myco toxins, and many of the rules only apply to certain genus. Identifying a new fungi is often an interesting and exciting process. Its well worth while to take the time to learn the basics.
I will provide details and photos of the different mushrooms I have eaten, however the onus is on the individual to always do your own due diligence before consuming any wild food. The first question should always be “what species is it?” and not “is it edible?” Most mushrooms are not edible and many that are have look alikes with unknown edibility. I never eat a new mushroom species unless I am one hundred percent sure I know what it is and I have double checked, generally it will be the second or third time I have found this species that I try it, then its only a very small taste of cooked mushroom. Its never safe to assume a mushroom is edible and its not reliable to have someone else ID the mushroom for you, on a facebook page for example.
Unfortunately researching edibility of Australian mushrooms is likely to leave you with more questions then answers. We have to use a variety of different sources. A Field Guide to Australian Fungi by Bruce Fuhrer is our best field guide. There are some other blogs with information about edibility the two best are Tall Trees and Mushrooms and Mushroaming. The Queensland Mycological Society has an excellent online field guide. Fungi map also has one. The Australian Wild Mushroom Hunters Facebook page is good. Mushroomexpert is a North american website that is helpful. wikipeadia and a google image search once you have a name are also useful. I also like using the Atlas of living Australia to search for records of fungi. In short, we have a great tool at our disposal, its called the interweb, so use it but don’t expect to always get a clear cut answer on edibility.
That’s enough for now, Happy Foraging!
