Xylographa trunciseda (Th. Fr.) Minks ex Redinger

Rare boreal species, specialized to hard wood of conifers. First published from the Czech Republic in the recent monography of the genus Xylographa(Spri­bille et al. 2014), which revised a collection by V. Kuťák from the Krkonoše Mts from the first half of the 20th century. Recently, it was also found in mountain old-growth forests in the Šumava Mts, specifically Mt Zátoňská hora and Mt Boubín. Xylographa trunciseda usually grows on wet lying conifer wood in old-growth forests. Apothecia are pale and short, thallus endosubstratal, containing diagnostic confriesiic acid (Spribille et al. 2014), which facilitates easy identification due to its fluorescence under UV light.
