This fungus is from a collection I did from the air on my balcony for 60 minutes. The top is on the left and the bottom on the right. The top is fluffy, with white and pink colours. The bottom is a pink that is quite light except in the centre where it gets a bit darker. It has grown radially about 0.6cm in 18 days, relatively average compared to others in my collection, so quite slow. I believe this is most similar to Fusarium oxysporum because of the colour and top texture. It is quite a small sample I have though, so there may be many differences that I cannot yet see without magnification.
