Daldinia petriniae Y.M. Ju, J. D. Rogers & F. San Martín,

Mycotaxon 61: 275 (1997)

Stromata semiglobose, aggregated and sessile. The KOH-extractable stromatal pigments

vinaceous to vivid purple ( Fig. 1I ). Ascospores inequilateral, dark brown, 10–14 × 6–7 µm. Specimens examined:

1) Poland: Western Carpathians , the Bieszczady Zachodnie Mts. , Duszatyn, the Przełom Osławy Reserve, on a standing dead trunk (ca. 6 cm in diameter) of Alnus incana , 6 April 2012, leg. A. Chlebicki, KRAM F without number .

2) Poland: Western Carpathians , the Bieszczady Zachodnie Mts. , Prełuki near Komańcza and Osławica River, on a dead, small trunk (7 cm in diameter) of Alnus incana , 9 April 2012, leg. A. Chlebicki, KRAM F without number .

3) Poland: Western Carpathians , the Bieszczady Zachodnie Mts., Nasiczne, on a dead trunk of Alnus incana , 26 December 2011, leg. A. Wilczek, KRAM F without number .

Comments: It was collected and determined by P.Drzewiecki in Mohle, Kujawsko-Pomorskie Region, on the trunk of a young alder ( Snowarski, 2014). Karasiński ( Wojewoda et al., 2016) also noted this species in the Gorce Mts. and Domański et al. (1967) reported it from branches of Alnus incana (as D. concentrica ) in the Bieszczady Zachodnie Mts. The fructification of the species begins in autumn. It is the most common species of Daldinia in KRAM F.This species differs from D. concentrica by its vivid purple pigments and smaller ascospores. Daldinia petriniae is similar to D. eschscholtzii but the latter species occurs in tropical zones.
