Recent observations of sooty bark disease of sycamore maple in Prague (Czech Republic) and the phylogenetic placement of Cryptostroma corticale

2014

Summary The anamorphic fungus Cryptostroma corticale (Xylariaceae) causing sooty bark disease (SBD) of Acer pseudoplatanus has been reported within the past decade in several European countries. In the last decade, severe drought conditions during summer also resulted in an outbreak of SBD in park areas in Prague (Czech Republic). Trees with the typical syndromes were recorded in four localities in Prague. Some trees were also located in the alluvial plain of the Vltava River with groundwater available all year long. We suppose that the trees were stressed by full water saturation for several months after flood in 2012 and that SBD was triggered by anoxia and subsequent phytopththora root rot. Sterile fungi isolated from one tree and one lesion were identified as C. corticale based on the similarity of their ITS rDNA sequences with strains of C. corticale in a public collection. Furthermore, C. corticale was placed in the family Xylariaceae within the genus Biscogniauxia based on phylogenetic analysis of four genes (ITS nrDNA, actin, RPB2 and β‐tubulin). The closest relatives are B. bartholomei and Graphostroma platystoma.

“…Therefore, two data sets of ITS rDNA and ACT‐RPB2‐TUB (further referred to as ART) from studies of Pažoutová et al. () and Mirabolfathy et al. (), respectively, were updated with the newly generated sequences of C. corticale and Graphostroma platystoma (Schwein.)…”

Resurrection and emendation of the Hypoxylaceae, recognised from a multigene phylogeny of the Xylariales

A multigene phylogeny was constructed, including a significant number of representative species of the main lineages in the Xylariaceae and four DNA loci the internal transcribed spacer region (ITS), the large subunit (LSU) of the nuclear rDNA, the second largest subunit of the RNA polymerase II (RPB2), and beta-tubulin (TUB2). Specimens were selected based on more than a decade of intensive morphological and chemotaxonomic work, and cautious taxon sampling was performed to cover the major lineages of the Xylariaceae; however, with emphasis on hypoxyloid species. The comprehensive phylogenetic analysis revealed a clear-cut segregation of the Xylariaceae into several major clades, which was well in accordance with previously established morphological and chemotaxonomic concepts. One of these clades contained Annulohypoxylon, Hypoxylon, Daldinia, and other related genera that have stromatal pigments and a nodulisporium-like anamorph. They are accommodated in the family Hypoxylaceae, which is resurrected and emended. Representatives of genera with a nodulisporium-like anamorph and bipartite stromata, lacking stromatal pigments (i.e. Biscogniauxia, Camillea, and Obolarina) appeared in a clade basal to the xylarioid taxa. As they clustered with Graphostroma platystomum, they are accommodated in the Graphostromataceae. The new genus Jackrogersella with J. multiformis as type species is segregated from Annulohypoxylon. The genus Pyrenopolyporus is resurrected for Hypoxylon polyporus and allied species. The genus Daldinia and its allies Entonaema, Rhopalostroma, Ruwenzoria, and Thamnomyces appeared in two separate subclades, which may warrant further splitting of Daldinia in the future, and even Hypoxylon was divided in several clades. However, more species of these genera need to be studied before a conclusive taxonomic rearrangement can be envisaged. Epitypes were designated for several important species in which living cultures and molecular data are available, in order to stabilise the taxonomy of the Xylariales.

The genus appears paraphyletic (Pažoutová et al 2010, Peláez et al 2008, Raimondo et al 2016 together with other related, but morphologically dissimilar genera, such as Camillea Fr., Obolarina Pouzar and Graphostoma Piroz., forming a clade distant from the species of Xylaricaeae in the traditional sense. Accordingly the genus Biscogniauxia has been tranferred to the Graphostomataceae (Wendt et al 2017).…”

Two species of pyrenomycetes, Biscogniauxia mediterranea and Hypoxylon fuscoides, are reported from the Czech Republic for the first time. Descriptions of both species, based on the authors' collections, are provided together with notes on their distribution and ecology in the Czech Republic and Europe. Additionally new records and short discussions regarding 20 other less common taxa of pyrenomycetes of the genera Biscogniauxia, Euepixylon, Hypoxylon and Nemania (traditionally placed in Xylariaceae) in Bohemia, Czech Republic, are supplied, and recommendations for a future version of the Czech Red list of macromycetes are given.
