 Historically , Chorioactis was considered to be in the family Sarcosomataceae . A 1983 monograph on the family included Chorioactis in the tribe Sarcosomateae ( along with the genera Desmazierella , Sarcosoma , Korfiella , Plectania , and Urnula ) , a grouping of fungi characterized by having spores lacking small wartlike projections ( verruculae ) capable of absorbing blue dye . A 1994 study of the structural features of the asci and the ascospores concluded that Chorioactis was more closely aligned with the Sarcoscyphaceae , although it conceded that the layering of the cells comprising the walls of the ascus differed considerably from the other members of the family . It was not until 1999 that the results of phylogenetic analysis firmly challenged the traditional classification , showing C. geaster to be part of a distinct lineage , or clade , that includes species in the genera Desmazierella , Neournula , and Wolfina , taxa that were distributed among both families . This analysis was later corroborated when it was shown that the grouping of these four genera ( by then called the " Chorioactis clade " ) represented a sister clade to the Sarcosomataceae , and a new family , the Chorioactidaceae , was erected to contain them . Although C. geaster shares some characteristics with the other Chorioactidaceae genera , including dark @-@ colored superficial " hairs " on the outer surface of the fruit bodies , it is distinguished from them by its tan to orange ( rather than black ) hymenia .
