Colonies vary from massive to plate-like or encrusting, showcasing an uneven surface. The corallites, formed through extratentacular budding, are conical and often irregular in both shape and size, ranging from 2.5 to 4 mm in diameter. Septa may be present in two slightly differing orders or may not follow a specific order. Columellae are well-developed and walls consist of thickened septa. The costae exhibit variability but are typically well-developed, featuring distinct dentations. The coloration spans shades of brown, grey or yellowish-green.
