Ganoderma resinaceum |
Ganoderma resinaceum is a rare poroid fungus that persists throughout the year. The yellow resin from the edges of this large bracket hardens rapidly. As the fruiting body ages, this beautiful fungus turns black and can then be mistaken for the Hoof Fungus, Fomes fomentarius. This tough, bitter bracket is inedible. When it is cut, a yellow resin oozes from the fungus and rapidly sets; the specific name reflects this characteristic. |
Description |
A startling sight, this large bracket fungus
usually occurs singly at the base of broad-leaf trees, particularly oak,
and less often on fallen trunks and large branches.
15 to 35 cm across and 4 to 8 cm thick, the fruiting body has a light yellowish margin and an orange top. |
Tubes and Pores |
The tubes are 8 to 10 mm deep.
The small round pores are white when the fruiting body is young, turning brown with age or when bruised. |
Spore print |
Brown. |
Odour/taste |
Spicy odour and a bitter taste. |

On broad-leaf tree trunks, particularly oak. |
