Definition
Cora smaragdina is a species of basidiolichen in the family Hygrophoraceae. It is a member of the genus Cora, which comprises lichenized fungi that form symbiotic associations with photosynthetic partners, typically green algae.
Overview
The species belongs to the order Agaricales and is part of the diverse group of basidiolichens predominantly found in tropical and subtropical regions. Cora smaragdina was formally described in recent scientific literature; however, the exact year of description, author(s), and type locality are not confirmed in the available sources. The taxon is recognized by its distinct morphological and ecological traits that differentiate it from other members of the genus Cora.
Etymology/Origin
The specific epithet smaragdina derives from the Latin adjective smaragdīnus, meaning “emerald” or “emerald‑green.” This name likely refers to the characteristic greenish coloration of the lichen’s thallus observed in living specimens.
Characteristics
- Thallus: The thallus is foliose to lobate, exhibiting a vivid green to turquoise hue reminiscent of an emerald, which is unusual among many Cora species that are typically grayish or brownish.
- Surface texture: The upper surface is smooth to slightly wrinkled, while the lower surface may be loosely attached to the substrate.
- Reproductive structures: As a basidiolichen, Cora smaragdina produces basidiocarps (often referred to as “basidiomata”) that are inconspicuous and embedded within the thallus. Spore morphology follows the typical basidiospore characteristics of the Hygrophoraceae.
- Habitat: The species is presumed to inhabit humid, shaded environments such as cloud forests or mossy montane areas, growing on bark, rocks, or soil. Precise distribution data are not confirmed.
- Ecology: Like other lichens, Cora smaragdina contributes to nutrient cycling, provides microhabitats for invertebrates, and participates in the epiphytic community dynamics of its ecosystem.
