Sistotremastrales – Facesoffungi number: FoF 12855

Sistotremastrales L.W. Zhou & S.L. Liu, ord. nov.,

MycoBank number: MB 559875; Index Fungorum number: IF 559875; Facesoffungi number: FoF 12855;

Description

Sertulicium and Sistotremastrum formerly belonging to Trechisporales are segregated as the new order. Sistotremastrales is characterized by corticioid basidiomes on wood, basidia with four to eight sterigmata and smooth basidiospores. Comparing with the circumscription of Trechisporales sensu He et al. (2019) and Spirin et al. (2021), some species in the reduced concept of Trechisporales after the exclusion of Boidinella (below), Litschauerella (below), Sertulicium, Sistotremastrum and Sphaerobasidium (below) also have smooth basidiospores, and thus are similar to species bearing basidia with four sterigmata in Sistotremastrales; however, species of Trechisporales differ in soft basidiomes, subicular hyphae with ampullate septa and presence of cystidia with various shapes (Spirin et al. 2021).
