# Foliose Lichen (*Menegazzia asahinae*)

Foliose lichens are unique organisms made of a fungus and an alga living together. They can be found on rocks, trees, and even soil, adding beautiful colors to nature.

## Appearance

The Foliose Lichen has a flattened, leafy appearance, often pale greenish-grey with a somewhat wrinkled or pitted surface. It can be distinguished by small, round holes or perforations that dot its upper surface. These unique openings create a delicate, net-like look.

## Taxonomy

- **Kingdom:** Fungi
- **Phylum:** Ascomycota
- **Class:** Lecanoromycetes
- **Order:** Lecanorales
- **Family:** Parmeliaceae
- **Genus:** Menegazzia

## Interesting facts

- Lichens are often the first living things to grow on bare rocks, slowly breaking them down.
- Many tiny insects and mites live \*inside\* foliose lichens, finding perfect shelter and moisture.
- Scientists can tell how clean the air is by studying which types of foliose lichens grow there.
- Some foliose lichens can live for thousands of years, making them among Earth's oldest living things!

## Special abilities

- **Air Purifier:** Foliose Lichen can absorb water and nutrients directly from the air, because of their unique spongy structure.
- **Ancient Survivor:** Foliose Lichen can dry out completely and rehydrate later, which helps them survive extreme weather for centuries.
- **Teamwork Power:** Foliose Lichen has a fungus and an alga working together, helping them create their own food and protect each other.

## Measurements & details

- **Height:** 0.1-1 cm
- **Edible:** inedible
- **Growth Substrate:** wood
- **Season:** Year-round

## Ecological connections

- **Depends on:** Japanese Cedar (*Cryptomeria japonica*) — This lichen grows on its bark for support.
- **Shelter:** [Great Tit](https://www.snappit.app/explore/great-tit) (*Parus major*) — Uses bits of lichen to camouflage its nest.
- **Eats:** Asian Tramp Snail (*Bradybaena similaris*) — Graze on the lichen's surface for nutrients.

## Traits

- [Lichen](https://www.snappit.app/explore/traits/lichen): This trait describes a composite organism resulting from a symbiotic association between a fungus and a photosynthetic partner, typically an alga or cyanobacterium.
- [Spore Producing](https://www.snappit.app/explore/traits/spore-producing): Spore-producing organisms reproduce by releasing small, often single-celled, reproductive units called spores.
- [Ancient Lineage](https://www.snappit.app/explore/traits/ancient-lineage): This trait signifies organisms belonging to a very old evolutionary group with ancestors dating back millions of years.
- [Forest](https://www.snappit.app/explore/traits/forest): Forest habitats are terrestrial environments dominated by dense tree cover, supporting a high diversity of plant and animal life.

## Safety

**Danger:** 1/5 · Very low

Enjoy looking at lichens, but avoid touching or picking them to let them thrive.

## Frequently Asked Questions

### How to identify Foliose Lichen?

Compare the cap shape, the underside, the stem and base, and whether the fungus grows on wood or soil. Some fungi have gills, others pores or teeth. A cap seen only from above often hides the most useful features. Mushroom Identifier: upload a photo and compare the visible details.

inedible

### Where is Foliose Lichen usually found?

Various surfaces like rocks, trees, and soil

### What does Foliose Lichen grow on?

wood

### When is Foliose Lichen in season?

Year-round
