Today's Mushroom

Today's mushroom is Rhizina undulata (Pine firefungus). It grows in North America, Europe.

Dimensions: 2-10 cm diameter

Description: Rhizina undulata, also known as Pine firefungus, is a large, irregular, brown or black fungus that grows in clusters on burned soil or conifer debris. The mushroom is parasitic on conifer seedlings and has caused considerable damage to tree plantations worldwide. It grows infrequently from early summer to early autumn.

Fruiting body flat, with irregular lobes, and attached to the growing surface on the entire lower side by numerous whitish to yellowish rhizoids resembling plant roots. The margin is pale yellow, similar to the underside, and wavy and irregular, while the rest of the fruiting body is dark purple-brown to blackish. Surface sticky as moist. In very young fruit bodies, the surface is white. The brown colour initially appears in the centre and expands rapidly thereafter. The flesh is reddish brown, tough and thick. Spores dark brown or black.

Microscopic Features: The spores are fusiform (fuse-shaped), apiculate, minutely verricose when mature, with one or two oil drops. They measure 30–40 µm in length and 8–11 µm in width.

Many mushrooms are poisonous and some are lethally poisonous. It can be very difficult to distinguish between an edible and a poisonous mushroom. Because of that, we strongly advise against consuming wild mushrooms, and this site does not contain any information about the edibility or toxicity of mushrooms.

Although efforts have been made to ensure accuracy on this website, the information may contain errors and omissions. Therefore, the information presented here is for informational purposes only and should not be relied upon as any basis for consuming any plants or mushrooms.
