Remarks (internal):The genus reminds of Aleurodiscus in the size and structure of the spores, of Xenasma in the presence of numerous pleurobasidia and in having a thin fruitbody with dense and indistinct hyphal texture, and of Gloeocystidiellum in the combination of the characteristics of amyloid, verrucose spores and presence of sulfocystidia. It differs from all species of Aleurodiscus by the lack of acanthohyphidia and dendrohyphidia, from Xenasma by the presence of sulfocystidia, and from Gloeocystidiellum by the presence of pleurobasidia.
