Free Images of Lichens
Cladonia pyxidata

Right click on any portion of the image showing and chose "save as". 

 

 

 

*** Warning ***

Although there aren't many lichen that are poisonous, there are some that are high in vulpinic or usnic acid and they are toxic. 

While I have tried to link images with lichen names, I am not a specialist in this field.  I have used books and images to try to look up, categorize and name the various species.  My identification should in no way be relied upon as accurate. YOU alone are responsible for properly identifying any lichen that you may be interested in.  I have attached names to images which I merely THINK resemble the species.

I am grateful for corrections to taxonomic determinations, please contact me at FreeTiiuPix

 

Cladonia pyxidata is also known as the "Crowned Pixie-Cup" lichen.  Looking somewhat like miniature golf-tees or trumpets, this species has a sprinkling of light-grey-green "pixie dust" (squamules) between them - this is part of the lichen.  While some Cladonia are smooth, this species has a rough appearance as if covered in grains.  If you look very closely, the rim of the cup has more reddish grains (apothecia).  The stem has greyish/green scales growing larger further down a narrowing stem.  The undergrowth of the cups is a mass of flattish scales.

These specimens were photographed at the based of a rotting tree stump at Watkins Glen State Park in the New York Finger Lakes region in July.  

This species looks very similar to Cladonia chlorophaea and other members of the Cladonia Family that are shaped like golf-tees:  Cladonia Fimbriata, C. carneola, C. cericornis, C. pocillum and C. coccifera.

Cladonia pyxidata are commonly found growing on the sides of rotting tree stumps, often with British soldiers and common Powder Horn lichens (Cladonia coniocraea).  The common Powder Horn is not horn shaped.  

Did you know...

that Pixie cups are squamulose lichens since they are scaly, but also foliose since they are leafy.

Lovely Lichens &
Magnificent Mosses

 

 

 

 

 

 

 

Lichens - Two types of organisms living together - a fungus and an alga.  The fungus makes the body that protects the alga, and the alga provides the food for the fungus.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Thoreau once wrote:  "I find myself inspecting little granules as it were on the bark of trees - little shields or apothecia springing from a thallus - such is the mood of my mind - and I call it studying.

 

 

 

 

 

 

 

 

 

 

Classification - 

Lichens were problematic for biological classification but are now classified as fungi under the genus and species of the host fungus.
