A gray
(green when wet) foliose lichen with masses of yellow soredia on
the upturned margins, common at the bases of conifers in the
foothills. It never fruits. The name Vulpicida has been
given to lichens, some of which in olden times were mixed with meat
used as bait to poison foxes and wolves. |

Xanthoparmelia (Parmelia) coloradoënsis [from
Colorado]. |
|
|
|
|
|
|
|
|
The ''green
parmelias" are abundant and diverse in all mountainous and desert
parts of the world. They are so abundant that they are actually
responsible for the greenish cast common to the mountains
themselves. The species are only distinguished by chemical
analyses. X. coloradoënsis has no isidia or soredia, and
forms a thallus loosely attached to rocks; the underside is
pale. |
