            <p> Oceanitis abyssalis Y. Nagano &amp; Abdel-Wahab sp. nov. Figs. 2–3 </p>
            <p>MycoBank no.: MB 851445.</p>
            <p> Diagnosis: This species differs from the other four species of  Oceanitis , namely  O. scuticella ,  O. cincinnatulum ,  O. unicaudatum and  O. viscidulum by having unicellular ascospores that are fusiform, curved or sigmoid in shape, two type of ascospores appendages: one polar uncoiling appendage and tree-like appendages that develops throughout the ascospores’ length; semi-persistent asci and cream-colored, drop-shaped ascomata (Dupont et al. 2009; Kohlmeyer 1977; Jones &amp; Le Campion-Alsumard 1970a, 1970b). </p>
            <p>Type: The Northwest Pacific Ocean, off the coast of Japan, (35°55.61′N, 144°57.87′E) under the Kuroshio Extension, on the sunken wood found on the abyssal plain at 5707 m water depths, 2 Sep 2019, Y. Nagano, holotype TNS-F-70722.</p>
            <p>Gene sequences holotype: LC789975 (LSU), LC777827 (ITS), LC789976 (SSU).</p>
            <p> Etymology: The epithet  abyssalis refers to the abyssal plain where this species was collected. </p>
            <p> Ascomata 1.2–1.6 mm high, 0.98–1.2 mm diam., superficial, drop-shaped, papillate, ostiolate, cream-colored, yellowish or brownish, subiculate, fleshy, single or gregarious. Ostioles 470–545 μm in length, 90–110 μm diam., ostiolar canal periphysate; periphyses 21–39 μm in length, 1–2 μm wide.  Peridium 290–400 μm wide at the upper part of the ascomata, 120–160 μm wide at the lower part of the ascomata, 3-layered, forming a textura angularis; outer layer 40–50 μm wide in the upper part of the ascomata and consists of 5–7 cell layers of light-brown, thick-walled, polygonal cells, 10–20 μm wide in the lower part of the ascomata and consists of 2–4 cell layers of flattened, thick-walled cells; median layer 230–280 μm wide in the upper part of the ascomata and consists of 15–28 cell layers of hyaline, thick-walled, polygonal cells that are with large lumina and elongated to outside and small to inside, 10–20 μm wide in the lower part of the ascomata and consists of 5–9 cell layers of polygonal, thick-walled cells; inner layer 28–45 μm thick, consists of 7–11 cell layers of hyaline, flattened, parallel, thick-walled cells. Paraphyses absent, center of immature ascomata is filled with hyaline, thin-walled, polygonal pseudoparenchymatous cells which are eventually compressed by the asci. Asci 83–115 × 15–20 μm (mean =95.7 × 17.1 μm, n=25), 8-spored, unitunicate, clavate or fusiform, thin-walled, with rounded apex, semi-persistent, short pedicellate, ripening successively on an ascogenous tissue at the bottom of the ascomatal venter, becoming detached at maturity at the base and pushed upward by young asci. Ascospores 58–77 × 4–5 μm, elongate fusiform, curved or sigmoid, unicellular, hyaline, guttulate, with one apical appendage; appendages 6–16 μm long, 0.5–2 μm diam, filamentous, uncoiling, tapering toward the apex, wavy, adhering with its base to the apex of the ascospore, deciduous; occasionally ascospores develop tree-like appendages throughout its length while within the ascus or after its release (Fig. 3). </p>

            <p> Oceanitis scuticella-like organisms and phylogenetic analyses </p>
            <p> Dupont et al. (2009) recorded twelve collections of  Oceanitis scuticella -like fungus from trawled samples from the bottom of the South Pacific Ocean off Vanuatu from depths between 551 m and 1273 m. The authors identified their fungal collections as  O. scuticella , although it has a significantly different morphological characteristics from the original collection of  O. scuticella that Kohlmeyer described from the Gulf of Angola, Atlantic Ocean, by having stromatic ascomata vs. aggregated ascomata and a thinner walled peridium than the Angola’s material (Dupont et al. 2009; Kohlmeyer 1977). Dupont &amp; Schwabe (2016) also reported a collection of  Oceanitis scuticella -like fungus from the sunken wood collected by trawling at abyssal depth from the Kuril-Kamchatka Trench in the Northwest Pacific Ocean. The authors identified their collection as  O. scuticella although it has unicellular ascospores with much smaller polar appendages and smaller drop-shaped ascomata than the Angola’s materials. We believe that both collections made by Dupont et al. (2009) and Dupont &amp; Schwabe (2016) represent undescribed species different from  O. scuticella , as the shape of ascomata and the spore septation are important characteristics for classifying fungal species. Detailed comparison of the morphology of  Oceanitis species is summarized in Table 1. </p>

            <p> In order to clarify the phylogenetic position of  O. abyssalis and  Oceanitis scuticella -like organisms, the LSU rDNA region of  O. abyssalis was aligned with other  Oceanitis sequences and other appropriate sequences retrieved from GenBank (Fig. 4). The new species,  O. abyssalis is well placed in the genus  Oceanitis clade with 100% support in the ML phylogenetic analysis.  Oceanitis abyssalis was placed with the Kuril-Kamchatka Trench material (M0229768) but located separately from other  Oceanitis taxa. The LSU and ITS rDNA sequences of  O. abyssalis showed 100% match with the Kuril-Kamchatka Trench material (M0229768). Both  Oceanitis abyssalis and the Kuril-Kamchatka Trench material (M0229768) have drop-shaped ascomata and unicellular ascospores. They were collected from a similar environment, the abyssal plain of the North Pacific Ocean. From a morphological perspective, as well as considering the 100% similarity in ITS rDNA sequences and ecological aspects of the collected material, we inclined to consider that M0229768 reported as  O. scuticella in Dupont &amp; Schwabe (2016) is a representative of  O. abyssalis . Although there are slight morphological differences between M0229768 and  O. abyssalis (Table 1), specifically, they differ in the dimensions of the ascospores (58–77 × 4–5 µm for  O. abyssalis vs. 52 × 2.3 µm for M0229768), and ascomata of  Oceanitis abyssalis are larger in size with a thicker, three-layer peridial wall (Dupont &amp; Schwabe 2016). Also, ascospores of  Oceanitis abyssalis have two types of appendages, while the collection of the Kuril-Kamchatka Trench has one polar uncoiling appendage. Some of these differences may result from a lack of detailed comprehensive observation and further findings of the specimens and detailed analyses will be needed to determine their precise identification. Therefore, we concluded in the present study that the Kuril-Kamchatka Trench material (M0229768) should be treated as  Oceanitis cf. abyssalis (Table 1 and Fig. 4). </p>
            <p> The South China Sea material (CP4157) was closely related to  O. abyssalis and Kuril-Kamchatka Trench material (M0229768) but placed independently within the  Oceanitis scuticella -like clade and showed 3 nucleotide differences in the LSU rDNA sequence and one nucleotide difference in the SSU rDNA sequence from  O. abyssalis (ITS rDNA sequence data is not available). As the detailed morphological information of the South China Sea material (CP4157) is not available, it cannot be discussed further. The Vanuatu materials (CP2457b, CP2429, CP2421) formed a clade being separate from CP4157 and  O. abyssalis . There are 3 to 4 nucleotide differences in the LSU rDNA sequence and 11 to 14 bases (2.5–3.0%) differences in ITS rDNA sequence between the Vanuatu materials and  O. abyssalis . Morphological and phylogenetic analyses suggested that the Vanuatu materials (CP2457b, CP2429, CP2421) are likely another undescribed  Oceanitis species different from the original  O. scuticella and  O. abyssalis . Therefore, we concluded in the present study that the Vanuatu materials (CP2457b, CP2429, CP2421) should be treated as unidentified  Oceanitis spp. (Table 1 and Fig. 4). The South China Sea material (CP4157), of which details are unknown, might be an another unidentified  Oceanitis sp. because of its independent phylogenetic position. To clarify the taxonomy of these collections and to understand the diversity within the genus  Oceanitis more accurately, additional collections, including  O. scuticella sensu stricto from the type locality, are needed. Furthermore, comprehensive morphological and phylogenetic studies are essential to formally describe these species. </p>
