Piptoporus oak is also known as Piptoporus quercinus, Buglossoporus quercinus or oak tinder. Species from the genus Buglossoporus. Included in the Fomitopsis family.
In some specimens, a rudimentary, elongated leg is determined
What does oak piptoporus look like
A rare representative with a one-year biological cycle. The hat is large, can reach up to 15 cm in diameter.
The external characteristics of oak piptoporus are as follows:
- At the beginning of the growing season, sessile fruiting bodies are elongated in the form of a drop; in the process of growth, the shape changes to a rounded, fan-shaped one.
- In young specimens, the flesh is dense, but not hard with a pleasant smell, white. Over time, the structure dries out, looks porous, cork.
- The surface of the cap is velvety, then the film becomes smooth, dry with longitudinal shallow cracks, the thickness is up to 4 cm.
- The color of the upper part is beige with a yellowish or brown tint.
- The hymenophore is thin, tubular, dense, porous, darkens to brown at the site of damage.
At the end of the biological cycle, the fruiting bodies become brittle and break easily.
Color does not change with age
Where and how to grow
It is quite rare, found in the Samara, Ryazan, Ulyanovsk regions and in the Krasnodar Territory. Grows singly, rarely 2-3 specimens. It parasitizes only on living oak wood. In the UK, it is listed as an endangered species, in Our Country it is so rare that it is not even listed in the Red Book.
Is the mushroom edible or not?
The fungus is poorly understood, so there is no information on toxicity. Due to the rigid structure of nutritional value is not.
Twins and their differences
Outwardly similar to piptoporus tinder fungus Hartig. Forms large fused fruiting bodies, similarity is determined only at the beginning of the growth of the Hartig tinder fungus in structure and color. It then becomes larger, with a stepped surface and thick, woody flesh. Inedible.
Grows only on conifers, more often on firs
The false aspen tinder fungus looks like a piptoporus with a hat, grows on living trees, mainly on aspens. Perennial inedible mushroom.
Contrasting coloration: dark brown or black at the base, and white with a grayish tint along the edges
Conclusion
Piptoporus oak – a representative with an annual biological cycle, is rare in Our Country. Grows singly or in small groups on living wood. The structure is rigid, cork, has no nutritional value.
