The genus is characterised by forming navicular to apothecial hysterothecia, exposing the green, yellow, orange, red, vinaceous or black colours of the hymenium which generally releases pigments in the presence of KOH. The exciple is smooth or striated, the asci bitunicate and ascospores have 1-5 transverse septa. To date, twenty-six species have been described from the Tropics. The present study aims to describe three new species in the Neotropics of Mexico based on molecular methods and morphological features. Illustrations and a taxonomic key are provided for all known species of this genus. from the Isla Cozumel Biosphere Reserve, from the Sierra Juárez, Oaxaca and from the Sierra Madre Oriental, Hidalgo are described as new species. With the present study, the number of species of known from Mexico is now increased to eight.
该属的特征是形成舟形至子囊盘状的子囊壳，露出子实层的绿色、黄色、橙色、红色、葡萄酒色或黑色，子实层在氢氧化钾存在下通常会释放色素。囊盘被光滑或有条纹，子囊双层壁，子囊孢子有1-5个横向隔膜。迄今为止，已从热带地区描述了26个该属物种。本研究旨在基于分子方法和形态特征描述墨西哥新热带地区的三个新物种。为该属的所有已知物种提供了插图和分类检索表。来自科苏梅尔岛生物圈保护区的、来自瓦哈卡州华雷斯山脉的以及来自伊达尔戈州东马德雷山脉的被描述为新物种。通过本研究，墨西哥已知的该属物种数量现已增加到八个。
