Gruppia

Gruppia is a genus of lichenized fungi in the family Ostropaceae. It is a group of organisms that are closely related to Thecosemia, another genus of lichens. Gruppia species are typically found growing on various surfaces, including rocks, trees, and soil.

The genus is characterized by its thin to medium-thick, crustose thallus, which forms a thin layer on the substrate. The thallus is usually green or yellowish in color, and the apothecia, or fruiting structures, are often prominent on the surface. Gruppia species are known to be relatively small, with most specimens measuring between 1 and 5 centimeters in diameter.

Several species of Gruppia have been described and documented, with a focus on their morphology and ecological characteristics. These species are commonly found in tropical and subtropical regions, although some have also been reported in temperate zones. Gruppia are thought to be particularly well-suited to surviving in areas with high humidity and moderate to high temperatures.

Gruppia species are considered to be relatively rare and are often understudied compared to more well-known lichenized fungi. Research on the genus has primarily focused on its taxonomic classification and the documentation of its morphological characteristics. Further studies on the ecological and biogeographic aspects of Gruppia species are needed to gain a better understanding of this unique group of organisms.
