Index Fungorum number: IF 551867; Faceoffungi number: FOF 01813; 1 morphological species (Species Fungorum, 2022), 1 species with molecular data
Saprobic on dead branches and twigs. Sexual morph: Ascomata superficial, globose to subglobose, with flattened base, solitary, scattered on the host surface, ostiole in the center, black, smooth-walled and without hair. Peridium comprising of brown to dark brown, arranged in a textura angularis. Hamathecium cylindrical, cellular, anastomosed, guttulate, septate, pseudoparaphyses. Asci 8-spored, bitunicate, cylindrical to cylindric-clavate, short pedicellate or sessile. Ascospores hyaline, fusiform, 1-septate in center, swollen, guttules in each cell, with or without mucilaginous sheath. Asexual morph: Undetermined (Adapted from Li et al., 2016).
Type species: Clematidis italica Tibpromma, Camporesi & K.D. Hyde
Notes: The genus Clematidis was introduced by Tibpromma, Camporesi & K.D. Hyde in Li et al. (2016) with Clematidis italica as type species and was placed in incertae sedis genus in Pleosporales. The morphological characteristic of this genus is similar to Lophiotrema (Li et al., 2016). Recently, Phukhamsakda et al. (2020), accommodated this genus under Clemataceae based on DNA sequence analyses with illustrations. There is one epithet in Clematidis based on molecular data coupled with morphological characteristics (Li et al., 2016; Index Fungorum, 2022).
