Asexual morph: Synnemata 285–850 × 8.7–32 μm (x̄ = 530 × 17.5 μm, n = 10), scattered, erect, rigid, dark brown to black, velvety, smooth. Conidiophores macronematous, synnematous, septate, cylindrical, branched, brown to dark brown, smooth. Conidiogenous cells 4.5– 34.5 × 1.3–3.3 μm (x̄ = 18.5 × 2.5 μm, n = 20), polyblastic, integrated, terminal, subhyaline to pale brown, smooth, denticulate, sympodial, each with several denticulate conidiogenous loci. Conidia 12.5–39.5 × 1.9–2.4 µm (x̄ = 20.7 × 2.1 µm, n = 20) solitary, fusiform to needle-shaped, straight or slightly curved, obtuse and tapering towards base, subhyaline to light brown, 3–4 septate, guttulate, smooth-walled.</p><p>Cultural characteristics:— Conidia germinating on PDA within 24 h. Colonies on PDA at room temperature reaching 30–35 mm diam. in three weeks at 25 °C, circular, slightly raised, entire, dry, surface rough, with sparse mycelium after four weeks, grayish brown in top view, reverse black, composed brown to dark brown, septate, smooth hyphae. Sporulation observed after 2 months in culture. Conidiophores macronematous, mononematous, cylindrical, straight or slightly flexuous, solitary, septate, unbranched, brown, paler towards the apex, denticulate conidiogenous cells. Conidiogenous cells polyblastic, integrated, terminal and intercalary, cylindrical, subhyaline to pale brown denticulate. Conidia 14–42.5 × 2–3.5 µm (x̄ = 22.3 × 3.3 µm, n = 40), solitary, fusiform to needle-shaped, straight, obtuse and tapering towards base, subhyaline to light brown, 3–4 septate, guttulate, smooth-walled.</p><p>Material examined:— Philippines, Bohol, Loon, Danicop-Ticugan Spring, on decaying wood submerged in a freshwater stream, 08 August 2023, T.A. R. Lopez, BHL-010-02-2 (UPVMI 24–0006), living culture UPVMICC 24– 0006 ; Philippines, Bohol, Loon, Danicop-Ticugan Spring, on decaying wood submerged in a freshwater stream, 08 August 2023, T.A. R. Lopez, BHL-010-02-3 (UPVMI 24–0007) .</p><p>Notes:—The isolate UPVMICC 24-0007 conforms to the asexual generic description of Phaeoisaria, characterized by indeterminate synnemata with septate or aseptate, ellipsoidal, obovoidal, fusiform-cylindrical, or falcate conidia (Hyde et al. 2020). An ITS BLASTn search revealed the closest known species to the isolate are Phaeoisaria sp. (HGUP-R 587), P. synnematica (AMH:10055), and Phaeoisaria sp. (CBS 143235). A multi-locus phylogenetic analysis revealed that the isolate grouped with P. filiformis strains, including the holotype MFLUCC 18-0124 and KUNCC:23- 13723 (FIGURE 1). Phaeoisaria filiformis is closely related to P. synnematica (FIGURE 1), but differs in conidiophore structure (solitary vs. compact, parallel appressed) and conidial morphology (filiform to needle-shaped, 3–4 septate vs. clavate to ellipsoidal, 0–1 septate) (Boonmee et al. 2021). In this study, the new collection is identified as P. filiformis based on both morphological and phylogenetic analyses. This study presents the first report of P. filiformis from freshwater habitats in the Philippines and provides the first documented description of its asexual morph.</p></div>	https://treatment.plazi.org/id/5B7987CA281AFFF5FF60FC80FAD80BED	Public Domain	No known copyright restrictions apply.

(2021)</p><p>Distribution:— CHINA (Dong et al. 2021).</p><p>Notes:— Saprodesmium was introduced by Dong et al.(2021) to accommodate a freshwater taxon, S.dematiosporum from China. In this study, a multi-locus phylogenetic analysis positioned S. dematiosporum as the sister taxon to Rhexoacrodictys chiangraiensis with 94% ML support (Figure 1). However, Saprodesmium dematiosporum was not included in the study of Win et al. (2024) when R. chiangraiensis was introduced. Wang et al. (2024) showed that S. dematiosporum clustered within Rhexoacrodictys clade, as a sister taxon to the three strains of R. melanospora (KUNCC 22–12406, KUNCC 22–12411, KUNCC 23–16529). Although Dong et al. (2021) highlighted distinct morphological differences between Rhexoacrodictys and Saprodesmium —specifically rhexolytic dehiscence with macronematous, long cylindrical conidiophores in Rhexoacrodictys, versus schizolytic dehiscence with micronematous, short conidiophores in Saprodesmium —phylogenetic evidence supports the inclusion of S. dematiosporum within Rhexoacrodictys . To prevent phylogenetic inconsistencies, we recommend transferring Saprodesmium to Rhexoacrodictys and synonymized S. dematiosporum under R. dematiosporum . Furthermore, we have emended the generic description of Rhexoacrodictys to incorporate key morphological traits from R. dematiospora .</p><p>Rhexoacrodictys erecta (Ellis &amp; Everh.) W.A.

Nim, CALINOG-002-03-001 (UPVMI 24–0005), living culture UPVMICC 24–0005.</p><p>Notes:— UPVMI 24–0005 closely aligns with the generic description of Rhexoacrodictys erecta (Baker et al. 2002) . In the multi-locus phylogenetic analysis (FIGURE 1), this isolate clustered with other R. erecta strains (HSAUPmyr4622, IFRD 500–016, HSAUPmyr6489) with strong support (100% ML, 1.00 BYPP). Compared to the isolate described by Baker et al. (2002), R. erecta UPVMI 24–0005 exhibits longer conidiophores (32–148 × 2.5–8.0 μm vs. up to 65 × 3.5–7 μm), but smaller conidia (17–24 × 12–21 μm vs. 24–39 × 15–29 μm). In this study, the new collection is identified as R. erecta based on both morphological and phylogenetic analyses. This is the first report of R. erecta from freshwater habitats in the Philippines.</p></div>	https://treatment.plazi.org/id/5B7987CA2814FFFBFF60FDFAFD210447	Public Domain	No known copyright restrictions apply.
