FIGURE 4 in Confusion surrounding Didymosphaeria-phylogenetic and morphological evidence suggest Didymosphaeriaceae is not a distinct family

FIGURE 4. Didymosphaeria rubi-ulmifolii (holotype). a. Immersed ascomata on the host surface b. Close-up of the ascomata c. Section of an ascoma. d. Close-up of peridium. e. Trabeculate, anastomosing and branching pseudoparaphyses. f–h. Asci with 8 spores. i–l. Brown, 1-septate ascospores with granulate ornamentation.
