03E287D9FFB87718FF52A91FFEF6FCB0.taxon	materials_examined	Holotype: — SAUDI ARABIA. Jizan city, Farasan Island mangrove (16 ° 44 ’ 22 ″ N, 42 ° 04 ’ 41 ″ E), on decaying intertidal wood of Avicennia marina (Forssk.) Vierh, 8 March 2012, coll. M. A. Abdel-Wahab (SUMCC H- 12008, holotype). Saprobic on decaying intertidal wood of Avicennia marina. Sexual morph: Stromata effuse covering large areas of the wood, up to 4 cm long. Entostroma 260 – 345 μm thick, prosenchymatous, well-developed, form thick-layer that connect perithecia, consists of woven tissue of fungal hyphae that mixed with host cells and are brown to dark brown. Entoplacodial 260 – 345 μm thick, prosenchymatous, form a disc around base of ostiole, consists of woven tissue of fungal hyphae mixed with host cells, brown to dark brown. Ascomata 430 – 500 μm high, 430 – 600 μm diameter (x = 460 × 490 μm, n = 10), ovate to pear-shaped, deeply immersed with long necks. Ostiole 320 – 550 µm long, 100 – 140 µm wide, tip of the papillae protruding above the wood surface, triangular in shape with tapered tip, brown to dark brown, filled with vertical parallel hyphae. Periphyses 9 – 18 × 1.8 – 2.3 µm. Peridium 40 – 63 µm thick, two-layered, forming textura intricata; outer layer 30 – 50 µm thick, made of thick-walled hyphae twisted together and mixed with host cells, brown to dark brown; inner layer 6 – 12 µm thick consists of flattened cells with narrow lumen, hyaline to apricot in colour. Hamathecium composed of numerous, hyaline paraphyses, non-septate, unbranched, semi-persistent, 1 – 3 μm wide. Asci 63 – 95 × 6.5 – 9.6 μm (x = 80 × 7.9 μm, n = 30), pedicel 23 – 46 × 2.9 – 4.1 μm (x = 32.9 × 3.6 μm, n = 30), 8 - spored, unitunicate, clavate, long pedunculated, J- in Lugol’s reagent, persistent, overlapping multiseriate. Ascospores 8.5 – 12 × 2.5 – 3 μm (x = 9.7 × 2.7 μm, n = 50), allantoid, brown, lacking sheath or appendages. Asexual morph: Unknown. Notes: — Cryptosphaeria jizanensis differs from the other five marine Cryptosphaeria species by possessing a well-developed entostroma that connects the perithecia and by having entoplacodial structures that form a disk around the base of the ostiole (Hyde & Rappaz 1993, Dayarathne et al. 2020). Both C. avicenniae and C. bathurstensis have a white line under the black hymenium in the ascomata, this white line is absent in C. eunomia, C. jizanensis, and C. maris-rubri. Ascospores in C. eunomia are hyaline to brownish, while they are brown in C. jizanensis. The sexual stage of C. halophila is unknown and phylogenetically distant from other marine Cryptosphaeria species (Fig. 1). C. jizanensis has prosenchymatous entostroma and entoplacodial stroma, while C. maris-rubri has pseudoparenchymatous ectostroma. C. jizanensis has longer asci (63 – 95 vs. 48 – 72 μm) and larger ascospores (8.5 – 12 × 2.5 – 3 vs. 6 – 8.4 × 1.6 – 2.4 μm) than C. maris-rubri. Multi-locus phylogenetic analyses placed C. jizanensis as a basal branch to a clade that contains C. avicenniae, C. bathurstensis and C. maris-rubri with high statistical support (81 % ML / 87 % MP / 92 % BYPP) (Fig. 1).	en	Abdel-Wahab, Mohamed A., Jones, E.

03E287D9FFBE771AFF52AFD5FBB8FC94.taxon	materials_examined	Holotype: — EGYPT. Red Sea, Safaga mangrove (26 ° 23 ’ 58 ″ N, 34 ° 06 ’ 54 ″ E), on decaying intertidal wood of Avicennia marina, 3 November 2020, Coll. M. A. Abdel-Wahab, (SUMCC H- 20010, holotype). Saprobic on decaying intertidal wood of Avicennia marina. Sexual morph: Stromata blackening the wood surface, effuse covering large areas of the wood, up to 8 cm long, ectostroma pseudoparenchymatous, 140 – 210 µm thick, consisting of polygonal, brown to dark brown cells with thick walls and large lumens that cover the wood surface and the perithecia. Entostroma absent. Ascomata 370 – 460 μm high, 465 – 570 μm diameter, globose to subglobose, deeply immersed under ectostroma, with long necks. Ostiole 220 – 250 µm long, 155 – 170 µm wide, the tip of the papillae protruding above the wood surface, periphysate. Periphyses 10 – 15 × 1 – 2 µm. Peridium 45 – 57 µm thick, two-layered, forming textura-angularis; outer layer 32 – 43 µm thick consisting of melanized polygonal cells, brown to dark brown and mixed with host cells; inner layer 10 – 25 µm thick consisting of flattened cells with narrow lumen and hyaline. Hamathecium composed of numerous, hyaline paraphyses, non-septate, unbranched, persistent, 1 – 4 μm wide. Asci 48 – 72 × 6 – 9 μm (x = 58.6 × 6.8 μm, n = 30), pedicel 18 – 34 × 2 – 3.2 μm (x = 23.1 × 2.3 μm, n = 30), 8 - spored, unitunicate, clavate, long pedunculated, J- in Lugol’s reagent, persistent, overlapping multiseriate. Ascospores 6 – 8.4 × 1.6 – 2.4 μm (x = 7 × 2 μm, n = 50), allantoid, brown, lacking sheath or appendages. Asexual morph: Conidiomata stromatic, multiloculate, 200 – 320 μm high, 160 – 225 μm diameter, subglobose, elongate or cleft-like, with a wide opening. Peridium 20 – 30 μm wide, consisting of parallel hyphae, pale brown. Conidiogenous cells 2 – 10 × 0.5 – 1.3 μm (x = 5.1 × 1 μm, n = 15), hyaline, unicellular, cylindrical or possessing a wide base and tapering tip, straight or slightly curved, arising from branched hyphae, producing one conidium, determinate, holoblastic conidiogenesis. Conidia of two types: α-conidia, 3 – 8 μm in diameter (x = 4.8 μm, n = 50), hyaline, globose, subglobose, clavate, or irregular shapes, surrounded by a gelatinous coat; and β-conidia, 35 – 57 × 0.8 – 1.2 μm (x = 48.7 × 1 μm, n = 50), one-celled, filiform, straight, curved, hook-like, or rarely twisted, hyaline to yellowish, appearing apricot in mass, oozing from the ostiole in tendrils. Notes: — Cryptosphaeria maris-rubri is distinguished from the other five marine species of Cryptosphaeria by its well-developed pseudoparenchymatous ectostroma, which covers the perithecia with papillae penetrating through it. This species has an asexual stage that produces two types of conidia, α and β, as well as smaller ascomata and smaller ascospores than other marine Cryptoshaeria species (Hyde & Rappaz 1993, Dayarathne et al. 2020). Phylogenetic analyses of the combined datasets of LSU, SSU, and ITS positioned C. maris-rubri alongside C. avicenniae and C. bathurstensis, with moderate bootstrap support (75 % ML / 68 % MP / 79 % BYPP) (Fig. 1).	en	Abdel-Wahab, Mohamed A., Jones, E.
