Clematidis Tibpromma, Camporesi & K.D. Hyde, in Li et al., Fungal Diversity 78: 10.1007/s13225-016-0366-9, [59] (2016)

Index Fungorum number: IF 551867; Facesofungi number: FoF 01813

Etymology: named for its occurrence on the host plant genus (Clematis).

Saprobic on Clematis vitalba L. in terrestrial habitats. Sexual morph: Ascomata solitary or scattered on the host surface, superficial, globose to subglobose, with flattened base, ostiole in the center, black. Peridium composing several layers of brown to dark brown, flattened pseudoparenchymatous cells arranged in a textura angularis. Hamathecium of 1.3–1.7 μm wide, long, cylindrical, cellular, anastomosed, guttulate, septate, pseudoparaphyses. Asci 8-spored, bitunicate, cylindrical to cylindric-clavate, short pedicellate or sessile. Ascospores overlapping 2–3-seriate, hyaline, fusiform, 1-septate in center, swollen with large guttules in each cell, lacking a mucilaginous sheath.

Type species: Clematidis italica Tibpromma, Camporesi & K.D. Hyde

Notes: Clematidis italica is morphologically similar to Lophiotrema (Lophiotrema nucula). Clematidis can be distinguished morphologically from Lophiotrema nucula (Fr.) Sacc. 1878 by having fusiform, 1-septate, straight or slightly curved and hyaline ascospores, but L. nucula has elliptic-fusiform brown ascospores with 3-septa (Tanaka and Harada 2003). Clematidis italica is introduced as a new genus based on morphology and combined LSU and SSU sequence phylogenetic support.
