| This tome includes detailed entries on more than 800 foliose, fruticose, and crustose lichens. |
|
| Therefore, no data were available in these species for the developmental transition of meristem from the juvenile to the mature foliose root. |
|
| Where thriving foliose and fruticose lichens can be found, the environment is clean and healthy. |
|
| In foliose lichens there is a lower cortex and in fruticose lichens the lower cortex is replaced by a central one. |
|
| The mechanism of the limpet effect involved sheltering of the limpet by the foliose fronds of this turf-forming alga. |
|
| In foliose lichens, there is a second cortex below the medulla. |
|
| Crottle, the largest foliose lichen, resembles crumpled leather and sometimes grows 90 to 120 centimetres in diameter. |
|
| On old silver birches the bark can become corklike and deeply fissured, with parts covered by large colonies of the yellow foliose lichen, Candelaria concolor. |
|
| Other common foliose genera include Cetraria, Parmelia, Peltigera, and Physcia. |
|
| But these leafy parts lack a lower cortex, which distinguishes crustose and squamulose lichens from foliose lichens. |
|
| Thirty-one species are of the crustose growth form, 27 are foliose, 8 are fruticose and 3 are squamulose. |
|
| The foliose forms are flat, leaflike, and loosely attached to a surface. |
|
| One foliose lichen and two moss samples were collected from trees at Drake's Seat on Saint Thomas. |
|
| For instance, Seki reported that the foliose green algae Ulva sp. |
|
| Fruticose, foliose, crustose, and squamulose lichens generally have up to three different types of tissue, differentiated by having different densities of fungal filaments. |
|
| In crustose and foliose lichens, algae in the photobiontic layer are diffuse among the fungal filaments, decreasing in gradation into the layer below. |
|
| Foliose lichens may sometimes branch and appear to be fruticose. |
|
| Foliose lichens on rock growing outward and dying in the center. |
