Description
Polycauliona bolacina is characterized by a thallus that has a yellow-orange color, often with a somewhat waxy texture. Its structure is primarily made up of thick squamules or convex areoles, which are either scattered or situated closely together. These components can extend up to 2 mm across and are slightly lobed. The apothecia (fruiting bodies) range from 0.7 to 2 mm in diameter, with orange disks and margins that are slightly paler in comparison. The tissues of the apothecia, including the exciple and cortex, consist of elongated cells arranged in an irregular pattern. Within the medulla, there are few crystals present. The ascospores of Polycauliona bolacina measure between 12.5 and 17.5 μm in length and 5.5 to 8.5 μm in width, with a septum that is 3 to 5.2 μm thick.
What it does
