Description
Index Fungorum Number: IF519747
Foliicolous, the host plant is Quercus palustris. Sexual morph: Undetermined. Asexual morph: coelomycetous. Conidiomata 354–522 μm (x = 427 μm, n = 5) diameter, 287 μm high, conspicuous, pycnidial, subglobose to sometimes lenticular in section view, semi-immersed, scattered, unilocular, with relatively thin stromatic base, black, glabrous. Beak of conidiomata long, 384 μm long, 13 – 61 μm wide. Peridium 18–42 μm wide (upper wall 25–42 μm (x = 33 μm, n = 7) wide; basal wall 18–26 μm (x = 27 μm, n = 7) wide), composed of 4 – 7 layers, with outer 3–5 layers light brown and inner layer hyaline, composed of thin-walled cells of textura angularis. Conidiophores up to 45 μm long, cylindrical, branched. Conidia 15.4 – 17 × 2.6 – 3.3 μm (x = 16.1 × 3 μm, n = 10), cylindrical to subcylindrical, slightly curved, 3-septate, hyaline, with an appendage at both ends; basal cell 2–2.8 μm long (x = 2.5 μm, n = 10), obconic, truncate at the base; 2 median cells 10.5–12.2 μm long (x = 11.3 μm, n = 10), cylindrical (second cell from the base 4.7–6.6 μm long (x = 5.6 μm, n = 10), third cell 4.6–6.7 μm long (x = 5.7 μm, n = 10)); apical cell 1.7–3.1 μm long (x = 2.7 μm, n = 10). Appendage single, cellular, unbranched, filiform, flexuous or straight appendage; apical appendage 7.9–9.1 × 0.8–1.1 μm (x = 8.7 × 1 μm, n = 6); basal appendage 7.8–9.3 × 0.7–1.1 μm (x = 8.5 × 0.9 μm, n = 6).
Material examined:— CHINA, Yunnan Province, Dali; 25°43′27″N 100°6′54″E, 2260 m alt.; 11 August 2019; Hai-Xia Wu leg; collected on a fallen leaf of Quercus palustris (IFRD 500-20) (new country record) .
Known hosts and distribution (based on molecular data):— Thailand, Yunnan China
Notes:— The genus, Immersidiscosia Kaz. Tanaka et al. (2011) was introduced by Tanaka et al. (2011) with I. eucalypti as the type species. The genus, morphologically resembles Discosia but phylogenetically distinct. Immersidiscosia eucalypti was reported from both temperate and tropical countries such as France, Italy, Japan and Tunisia (Tanaka et al. 2011; Hyde et al. 2017; Wijayawardene et al. 2017; Farr & Rossman 2021). This is the first report of I. eucalypti in China. Further collections are essentially required to study whether this taxon is pathogenic on Quercus species.
