Singh 2021	<div><p>Podosphaera filipendulensis Sanjay, Sanjeet &amp; Raghv. Singh sp. nov. (Figs. 1–4)</p> <p>MycoBank: MB 825553</p> <p>Diagnosis:— Differs from P. filipendulae by its smaller peridium cells, aseptate, shorter and narrower appendages, and constant number of ascospores per ascus.</p> <p>Type:— INDIA. Uttarakhand: Chamoli, Valley of Flowers National Park, 30° 43’ 59.99” N, 79° 37’ 59.99” E, on living leaves of Filipendula vestita (Wall. ex G. Don) Maxim. (Rosaceae), September 2017, leg. Sanjay Yadav, AMH 9934 (holotype), MH-BHU 1 (isotype).</p> <p>Etymology:— Latin, filipendulensis derived from the name of host genus.</p> <p>Symptoms on leaves of host plant, conspicuous reddish to reddish brown circular spots (1–5 mm diam.) on upper surface, lower surface with brown to blackish brown powdery masses irregularly distributed with ascomata (cleistothecia),heavy infection initially causes wilting and drying, ultimately death of leaves. Cleistothecia hypophyllous, scattered or sometimes gregarious, often between leaf trichomes of host plant, globose, initially hyaline but dark brown to blackish brown at maturity, 76–99(–124) μm diam., cleistothecial cells conspicuous, pseudoparenchymatous, thick, semitransparent, close to each other and irregularly polygonal, 4–14.5 μm diam. Appendages mycelioid, arising perpendicular to the cleistothecial surface, scattered, and radially elongated outward, mostly distributed over entire surface, 4–25 per cleistothecium, unequal in length, (14–)35–101(–172) × 1.6–4.8 μm, length varying between 0.2–3.5 times the diameter of ascomata, smooth, with blunt apex, initially hyaline but upon maturity become pale brown throughout, aseptate, unbranched, thick-walled. Ascus single per cleistothecium, 71–93 × 60–89 μm, subglobose to ellipsoid, sessile, smooth, hyaline, with dense cytoplasmic contents, thick-walled (1.2–4.1 μm), 8-spored, 10–22 μm diam. of the thin-walled apical portion of the asci (oculi). Ascospores ellipsoid to ovoid, sometimes fusiform, hyaline to very rarely olivaceous, smooth, thin-walled (0.63–0.85 μm), aseptate, 17–25 × 10–16 μm.</p> <p>Phylogenetic analysis clearly supports P. filipendulensis as an independent species (Fig. 5). P. filipendulensis clustered together with P. ferruginea var. ferruginea (Schltdl.) U. Braun &amp; S. Takam. and P. macularis (Wallr.) U. Braun &amp; S. Takam. (ML = 76, BI = 0.89).

Sphaerotheca reported on Rosaceae is provided in Table 1.</p> </div>	https://treatment.plazi.org/id/038787A14203AD7492ACFE921119FB39	Public Domain	No known copyright restrictions apply.
