Hyde 2018 [136,824,1588,1615] Sordariomycetes Xylariaceae Vamsapriya Fungi Xylariales 3 64 Ascomycota species yunnana sp. nov.  Etymology:—Named after the Province “ Yunnan”, China, from where this fungus was collected.     Holotype: HKAS 101752  Saprobicon dead bamboo culms. Sexual morph: Undetermined. Asexual morph: Hyphomycetous.  Myceliumimmersed in the substrate, composed of septate, branched, brown hyphae. Conidiophoresmacronematous, synnematous, dark brown, cylindrical, septate, branched at the apex, smooth-walled. Synnemata 0.7–1.1 mmlong, with apical fertile part 60–80 μm wide, middle part 40–55 μm wide, basal part 65–80 μm wide, superficial, solitary, scattered at random, erect, rigid, dark brown to black, composed of compactly arranged conidiophores. Conidiogenous cells6.7–9.3 × 3.8– 4.8 μm ( x= 8 × 4.3 μm, n = 20), monotretic, enteroblastic, integrated or discrete, cylindrical to subglobose, apically rounded, brown to dark brown, smooth-walled, Conidia50–70 × 9–11 μm ( x= 61 × 10 μm, n = 20), fusiform, broad at middle, straight to curved, brown, obtuse at base, rostrate at tip, septate, smooth-walled; body part 30–38 × 8–10 μm ( x= 35 × 9 μm, n = 20), initially 1–3-septate, up to 4–5-septate at maturity; apical rostrate part 15–30 μm long, 0–3-septate.   FIGURE 1.RAxML tree based on a combined ITS, LSU and RPB2 sequence dataset. The tree is rooted to  Cainia anthoxanthis(MFLUCC 15–0539) and  C. graminis(MFLUCC 15–0540). Bootstrap support values for ML (left) equal to or greater than 70% and the values of the BYPP) (right), equal to or higher than 0.95 are indicated above the nodes. Ex-type strains are in bold and the newly generated sequence is indicated in red bold.  Culture characteristics:—Conidia germinating on PDAwithin 24 hours at 20–25ºC, with germ tubes produced from one end. Colonies on PDAfast growing, reaching 5 cmafter one month at 20–25ºC; white, circular, after one week, cottony and pinkish after one month. Myceliumsuperficial to immersed in media, with dark brown, branched, septate, smooth hyphae.  Material examined:—  China, Yunnan Province, Honghe Prefecture, Pingbian County, near Tuanpo Reservoir, on dead bamboo culms,  20 September 2017, HB. Jiang, Pb006 ( HKAS 101752,  holotype!);  ibid. ( MFLU 17–1554,  isotype!), ex-type living culture, MFLUCC 18–0468, KUMCC 18–0008.  Notes:—  Vamsapriya yunnanais similar to  V. khunkonensis( Dai et al.2014)in having brown to dark brown, up to 5-septate conidia at maturity.  Vamsapriya yunnanahas 0–3-septate conidia with a 15–30 μm long apical appendage-like and wider apical fertile region (  V. yunnana: 60–80 μm vs. 20–35 μm:  V. khunkonensis). In addition,  V. yunnanaforms a distinct lineage, separated from  V. khunkonensisin a phylogram of  Vamsapriyaspecieswith strong support. Therefore,  V. yunnanais introduced as a novel species. 4929061301 [189,482,1698,1723] HKAS 3 64 HKAS 101752 1 holotype 4929061302 2017-09-20 HKAS China Pingbian County Tuanpo Reservoir Honghe Prefecture 4 65 HKAS 101752 1 Yunnan holotype 4929061303 2017-09-20 MFLU, MFLUCC, KUMCC China Pingbian County Tuanpo Reservoir Honghe Prefecture 4 65 MFLU 17-1554, MFLUCC 18-0468, KUMCC 18-0008 1 Yunnan isotype
