Patellariales D. Hawksw. & O.E. Erikss.

MycoBank number: MB 90491;Index Fungorum number: IF 90491; Facesoffungi number: FoF 08123.

Species of the Patellariales are saprobes on bark or wood, although some are lichenized (Jones et al. 2015). Ascomata are apothecial. Pseudoparaphyses are initially attached to both the base and apex, but later become free at the apex. Asci are cylindric-clavate and ascospores are mostly fusoid (Kutorga and Hawksworth 1997). Some species have aposphaeria-like and diplodia-like asexual morphs (Yacharoen et al. 2015), but these are rarely observed. Species are frequently found in terrestrial habitats and occasionally in aquatic habitats (Kirk et al. 2008; Jones et al. 2015). Multigene phylogenetic study on this group was provided by Pem et al. (2018). Phylogenetic placement of genera in this order are shown in Fig. 62. The divergence time for Patellariales is estimated as 276 MYA (stem age, Hongsanan et al. 2020).

Accepted families: Patellariaceae.
