The photo presented above is one of the three Fungi that grew from swabbing a shower curtain. As shown by the photo, the top presents a grey/light black coloured Fungi, with one circular milky white Fungi growing on top of it. However, the bottom photo, presents a yellow colour Fungi with the bottom of the circles being orange. As shown by the photo, the growth is moderate as it formed colonies. I would hypothesize this Fungi ID to be Sclerotina sclerotiorum based on the similarities in the morphology.
