The spike cap or slimy spike cap (Gomphidius glutinosus) is a good edible mushroom, similar to the copper spike but without the sweet flavour. However, it is best to peel off the cap in the forest, as otherwise black discolouration (oxidation) can occur in the mushroom basket in combination with other mushrooms (e.g. chanterelle). Although not poisonous, it is visually not very appealing.

The characteristic yellow foot and the slimy cap usually make this mushroom easy to identify.

The Spike Cap (Gomphidius glutinosus), is a mushroom with a mild taste and neutral odor. Its cap can grow up to 20cm in diameter and is slimy, often with black-brown spots. The flesh is white, turning gray with age, and yellow in the stem base. The stem is white with a yellowish tip and very slimy. The thick, waxy, and easily removable gills start off white and mature into gray-brown. This edible mushroom is commonly found in coniferous forests on acidic soil, forming a symbiotic relationship with spruce trees.

Look-Alikes of spike caps (Gomphidius glutinosus)

With its yellow colouring at the base and its slimy cap, the spike cap is usually an easy fungus to identify. It can be confused with other Gomphidius species (e.g. G. maculatus, G. roseus). The copper spike is also similar in appearance. These mushrooms are all edible.

Caution: Mushrooms Are Not Guesswork!

Only harvest mushrooms that you can identify with 100% certainty! The consequences can be life threatening if you are wrong. If you have the slightest doubt: do not eat the mushroom! This is not a mushroom guide! For correct identification consult a mushroom expert.

Spike caps (Gomphidius glutinosus) in the kitchen

Spike caps are not usually collected by many people, which is of course all the better for die-hard foragers because no one else will take them. They are actually very good mushrooms with a meety texture and a mild taste.

When collecting spike caps, it is advisable to peel off the slimy cap to prevent neighbouring mushrooms (e.g. chanterelles) in the basket from turning black due to oxidation.
