The photo presents a top and bottom photo of a Fungi growing from a brown root. As shown in the photo the Fungi is dark green from the sides, while the middle is fuzzy creamy white coloured ( with a bit of green growing on there). The bottom of the plate however, presents a dark red which is surrounded by white fuzzy Fungi. The growth rate of the Fungi is large because it seems like the Fungi covered the plate (it does not show colonies forming). I would therefore identify this Fungi to be Phytophthora megasperma based on the morphological similarities.
