The image shows a close-up of a trail with two types of lichens growing on it: liverwort Reboulia hemisphaerica and black cyanolichen.
* **Reboulia Hemisphaerica**
* The liverwort is light green in color, has no stem or leaves.
* It appears to grow directly from the ground.
* Its shape resembles a flat, round pad with slightly raised edges and concave centers.
* The pads are small, about 0.5 inches (1 cm) across.
* **Black Cyanolichen**
* The lichen is black in color, possibly because it lacks chlorophyll.
* It appears to grow directly from the ground as well.
* Its shape is harder to determine due to its small size and blending with the surrounding soil.
The image provides a detailed view of the two types of lichens growing on the trail. The liverwort Reboulia hemisphaerica is light green, has no stem or leaves, and grows directly from the ground in flat, round pads. The black cyanolichen lacks chlorophyll, giving it its dark color, and also appears to grow directly from the ground. – AI vision
La hepática Reboulia hemisphaerica y el cianolichen negro en un camino transitado en la reserva natural David E. Schob en 906 Ashburn Street. Estación Universitaria, Texas, 15 de enero de 2019. La imagen muestra un primer plano de una pista con dos tipos de líquenes creciendo sobre ella: hepática Reboulia hemisphaerica y cianolichen negro. * **Reboulia Hemisphaerica** * La hepática es de color verde claro, no tiene tallo ni hojas. * Parece crecer directamente desde el suelo. * Su forma se asemeja a una almohadilla plana y redonda con bordes ligeramente elevados y centros cóncavos. * Las almohadillas son pequeñas, de aproximadamente 0,5 pulgadas (1 cm) de diámetro. * **Cyanolichen negro** * El líquen es de color negro, posiblemente porque carece de clorofila. * También parece crecer directamente desde el suelo. * Su forma es más difícil de determinar debido a su pequeño tamaño y al mezclarse con la tierra circundante. La imagen proporciona una vista detallada de los dos tipos de líquenes que crecen en el camino. La hepática Reboulia hemisphaerica es de color verde claro, no tiene tallo ni hojas y crece directamente desde el suelo en almohadillas planas y redondas. El cianolichen negro carece de clorofila, dándole un color oscuro, y también parece crecer directamente desde el suelo. – Spanish translation
