Fungus Challenge Teams at Irchester

The Lab_13 committee and a team of year 5 students have been battling it out to grow the best fungus.


We had a bag of straw, and we had some mycelium of Oyster Mushroom Fungus. First we poured hot water into the bag of straw (to kill any bacteria), then we let it cool overnight before putting the Mycelium in. Ten we put the bag in a warm place with little sunlight. After 4 weeks, we got the bag of straw out and saw that the fungus had grown all through the straw: there were lots of while bits. We put the fungus in the fridge for 2 days to make it think it was autumn. After that we cut the bag open and put it somewhere warm with a little sunlight.

We each had a different job, it’s now Josh and Aiden’s job to spray it every day. The winning team is the one that grows the biggest fungus. I think ours might win as the year 5s forgot to put theirs in the fridge for two days. They have done it now but we are still two days in front of them.

About a week after being in the fridge, we started to see mushrooms growing from the straw! Last week on Tuesday, both teams got together to compare our mushrooms. The year 5 team had more mushrooms, but they were much smaller and a bit dried out. We only had 3 mushrooms, but they looked big and healthy. We think that the year 5’s put their mushroom somewhere a bit too warm so they dried out. After comparing our fungi, we tasted them! We fried them and compared the tastes of the two fungi.  Out of 12 people, 9 decided to try some, and 7 really liked the Oyster mushrooms. We decided to try and grow some more fungus so we turned the straw over and started again!
