I first found these mushrooms a few years back, a whole bunch of these fricken enormous clumps of mushrooms appeared in my neighbors pile of compost. Having never seen anything even close to these giant clumps before I was impressed and excited by the find but unable to get an ID that I was happy with, in my field guide the only genus that looked close was lylophyllum. Every year since they have fruited again over summer in the same spot, I would stop and admire them, take a few photos, take a few home, one time I even fried a few slices up just for a taste. They tasted pretty good but I spat them out unwilling to swallow a mushroom that I wasn’t able to ID.
Earlier this year (2017) we were driving around near Coramba and my partner said she saw some kinda big white mushroom, I turned around and found the second patch of these giants, the were growing from piles of soil mixed with gravel and organic matter that had been dumped by the road crew. Some of the clumps were rotten, others just emerging from the soil, over the back I found some with caps over 200 mm across standing over 300 mm above the ground, the biggest mushrooms I’ve ever seen. Not long after this I saw a post on the internet, local legend Darcey Browning from Darkwood had found his own patch and true to form gone straight to the press. He wasn’t having to much luck IDing them either.
Finally the other day I emailed my pictures to the Queensland mycological society and got a prompt reply from one of the head honchos, he said that he was 95 percent sure that they are Macrycybe crassa, and that he has found them in his own yard further north. Macrocybe crassa are eaten in some parts of Asia, most of the pictures and info I have found so far are from Thailand. There have also been a few attempts to cultivate them. Where to now with these novel giants? First i will send away a sample for dna analysis and if it comes back as Macrocybe crassa I will have a bit more of a taste next time I cross paths with these noble giants. I’m also keen to clone them and see if they can be domesticated. Stay tuned.
