Top 20 Most Common Mushrooms in Portugal

1. Common orange lichen

Common orange lichen was selected in 2006 by the United States Department of Energy as a model for genomic sequencing. Its widespread dispersal and bright yellow-orange color give the lichen its common name. It is primarily found growing on rocks, walls, and tree bark.

2. Fly agaric

In Northern Asia and Europe, fly agaric grows under trees near the winter solstice and is collected for ritual use tied to the season. Its characteristic shape and coloring are still ubiquitous in many European fairy tale illustrations and Christmas traditions. It is highly toxic.

3. Red cage

The red cage is a highly distinctive mushroom with a wild shape, even for a stinkhorn. Its fruitbody grows as a hollow, latticed structure, usually red or pinkish in color, that gives it the appearance of a rubber or plastic children's toy. A true stinkhorn, this species secretes a pungent-smelling slime that attracts flies - but repels humans!

4. Big sheath mushroom

These large white mushrooms bloom all over cleared, harvested fields, as well as pastures and roadsides. The scientific species name comes from Greek words meaning “glue” (glioio) and “head” (cephalus), in reference to the sticky surface of this mushroom’s cap. The big sheath mushroom looks so similar to the poisonous Deathcap and Destroying Angel mushrooms that it should always be left alone.

5. Split gill

Split gill(Schizophyllum commune) can be found across the globe. Uniquely, it is the only mushroom species known to display the capability to retract by movement. It is considered inedible, although not necessarily toxic. Furthermore, it is not recommended to smell this species, as the spores are capable of sprouting and growing in nasal passages.

6. Parasol

Found in clearings and grassy areas in late summer, the wild parasol mushroom has a snakeskin-patterned stem. The brown spots on its cap make it look a bit shaggy, but that name is reserved for its poisonous counterpart, the Shaggy Parasol (Chlorophyllum rhacodes). You can distinguish the two by the stems: the latter has a smooth stem and red flesh inside.

7. Common greenshield lichen

The common greenshield lichen is a familiar species in temperate forests around the world. It can be found growing on rock outcroppings and trees in a wide variety of habitats. Individuals can grow to be quite large and may be gregarious, forming large mats or sheets on suitable surfaces. Like other lichens, the common greenshield lichen will shrivel and harden when moisture is scarce.

8. Tree lungwort

Tree lungwort is a green lichen that can be found in humid areas of North America, Europe, and Asia. It grows regularly on trees, rocks, and in urban areas rich with moss. It can be used as a dye. Animals may consume tree lungwort or use it as nesting material.

9. Hairy curtain crust

This clustered, overlapping fungus is found all over the world, and is considered native across both the northern and southern hemispheres. Both its common name, hairy curtain crust, and its scientific name, Stereum hirsutum, aptly describe its most obvious features: it is quite tough (stereum) and the younger fruitbodies are notably hairy (hirsutum).

10. Oakmoss

Evernia prunastri grows shrubby on trees. The yellow-green lichen grows up to 10 cm. It consists of up to five millimeters wide shrubby branched bands with a light underside. At the edges of these open dusty (Sorale). Apothecias (with shiny brown disc) are rarely formed.

11. Shaggy mane

The shaggy mane mushroom is commonly found in North American and European grasslands. Some peoples foraged for its young egg-shaped caps, but it has more recently been found to be a bioaccumulator of heavy metals, meaning it pulls toxic metals up from the soil where it grows. As a result, shaggy manes should not be eaten. The mushrooms usually appear in clusters or “fairy rings.”

12. Blewit

The blewit mushroom grows in fallen leaves in autumn and winter, sometimes appearing in ‘fairy ring’ circles. It can be used to make a green dye when chopped and boiled in an iron pot. The scientific name, Lepista nuda, derives from Latin words meaning “bare goblet,” a reference to the shape and texture of the mushroom.

13. Hollyhock rust

Hollyhock rust (Puccinia malvacearum) is a parasitic fungus that produces a rust disease on the foliage of host plants such as hollyhocks and mallows. Hollyhock rust grows on the leaves, creating small brown spots on the undersides, then bright yellow or orange pustules on the tops. A severe infection can impair photosynthesis in the host plant. Its spores spread on the wind.

14. Turkey tail

The distinctively-striped turkey tail fungus grows on stumps and logs all over the forests of the northern hemisphere. It is, in fact, probably the most common species you will find. That doesn't mean this mushroom is plain, however; each cap is uniquely patterned. Look for bands of alternating textures as well as color.

15. Redlead roundhead

This colorful mushroom grows most commonly on woodchip mulch and in sandy pine forests of coastal areas around the world. The redlead roundhead is believed to have originated in Australia. It may look pretty enough to eat, but don’t; it is bitter, toxic, non-digestible, and likely to cause an upset stomach.

16. Chicken of the woods

Chicken of the woods is very noticeable in hardwood forests, appearing in clusters on standing tree trunks in bright orange and yellow hues that sometimes last through the entire winter. It is a parasite that causes an unfortunate brown heart rot, and is considered a particularly troublesome pest of Yew trees. If the fruitbodies can be seen, the tree is likely already beyond saving.

17. Common stinkhorn

The common stinkhorn (Phallus impudicus) grows incredibly quickly, sometimes nearing 30 cm in a single afternoon. Their caps are pitted in a way which makes them reminiscent of morels. However, there's little mistaking the common stinkhorn for a morel; the former, in addition to sporting a much longer stalk, has a clear and pungent odor.

18. Euphorbia rust

19. Jack-o'-lantern

The jack-o'-lantern (Omphalotus olearius) lives up to its nickname in more ways than one. Not only are the caps often large, round, and as orange as pumpkins, but at night these mushrooms even glow. In the darkness, their bioluminescent gills can be seen emitting a spooky green light. In fitting with the scary theme, this fungus is also extremely poisonous.

20. Blistered navel lichen

The foliose and umbilical thallus (attached by a single central crampon, the umbilicus), 3-6 (15) cm in diameter, is gray-brown to blackish-brown in dry weather, olive-green when it rained. Its upper surface is covered with convex pustules and bunches of brown-black coral isidia, the central part being covered with a white bloom. The pustules corresponding to propagules: the migration of these pustules from the center to the periphery gives rise to marginal isidies which ensure the vegetative reproduction of the thallus.
