Daldinia vernicosa Ces. & De Not.

Comment. Soc. Crittog. Ital. 1: 198. 1863 Stromata subglobose, sessile, shortly stipitate to distinctly stipitate. The KOH-extractable stromatal pigment purple, vivid violet to vivid brown, or vinaceous purple ( Fig. 1H ). Ascospores dark brown with broadly to narrowly rounded ends: (10,5)12–14 × 6.2–7.3 µm ( Fig. 2D ). Specimens examined: 1) Poland: Eastern Podkarpacie, Sandomierz Dell, Przemyśl, near the railway station in Przemyśl-Pikulice towards Sielec, near Wiar River, on dead wood, 14 September 1979, leg. W. Wojewoda, KRAM F 33838 (as D. concentrica ). 2) Poland: Niziny Sasko-Łużyckie, in Zielona Góra voivodeship, close to Zasieki and Lubsko, near the Polish-German border, on burned trunks of Betula sp. , April 1984, leg. B. Ginko, KRAM F 39306 (as D. concentrica ). 3) Poland: Lakelands Wschodniobałtyckie, in Augustowska Forest, the Perkuć Nature Reserve, Vaccinio myrtylli-Pinetum Juraszek 1928 forest, on a lying Betula trunk, 16 September 1974, leg. W. Wojewoda KRAMF 32456 (as D. concentrica ). 4) Poland: Lower Silesia, Sudety Mts., Przedgórze Sudeckie, Strzelińskie Hills, 1 km northeast of Biały Kościół, on a burned trunk of Prunus spinosa L., 26 March 1985, leg & det. A. Chlebicki, KRAM F 55346 (as D. fissa C.G. Lloyd ). 5) Poland: in Biebrza Valley, the Biebrza National Park, Ciszewo, Brzeziny Ciszewskie Forest, on a Frangula alnus Mill. host, 17 August 1991, leg. & det. A. Chlebicki, KRAM F 43103 (as D. fissa ). 6) Poland: Małopolska Region, Tarnów, near Lipie forest, on a dead trunk of Betula pendula , 31 June 1997, leg. M. Piątek, det. A. Chlebicki, KRAM F 56616 , (as D. fissa ).

Comments: The species was reported from Poland by Stadler et al. (2014) and Gierczyk et al. (2017). Chlebicki (2008) noted this species on Prunus spinosa , Frangula alnus and Betula pendula (as Daldinia fissa ). Stromata of this species are reported also on fire-damaged trees ( Stadler et al., 2014; Chlebicki, 2008). Stadler et al. (2014) recognised D. fissa as a synonym of D. vernicosa and suggested that D. fissa is an aberrant form with compressed stromata, damaged by insect larvae.
