Fungi associated with Cyclaneusma needle cast in Scots pine in the west of Poland

Needles of Pinus sylvestris with and without symptoms of Cyclaneusma needle cast, from the west of Poland, were examined for abundance and diversity of fungi using Illumina sequencing. Fungal communities were dominated by Ascomycota (93.6%-98.6% of OTUs). Basidiomycota and non-culturable fungi were less frequent. Needles were colonized by 260 taxa. Ascomycota, Basidiomycota and Glomeromycota were represented by 149, 39 and 1 taxa. Abundance of fungi was least in 1.5-year-old needles attached to twigs and greatest in fallen 2-year-old needles. Fungal communities had least diversity in 1.5-year-old needles and most diversity in 0.5-year-old needles of current growth. It was found that (a) the most common fungi were the needle pathogens Cyclaneusma minus, Lophodermium spp. and Sydowia polyspora; (b) less common potential pathogens were Cenangium ferruginosum, Coniothyrium complex, Desmazierella acicola, Neocatenulostroma germanicum and species in the genera Neodidymelliopsis, Pestalotiopsis, Phoma, Pleurophoma and Pyrenochaeta; (c) common primary or secondary saprotrophs included species of Alternaria, Aureobasidium, Beauveria, Cladophialophora, Cladosporium, Epicoccum, Exophiala, Lecanicillium, Penicillium, Cryptococcus and Kwoniella; (d) Lophodermium was represented mostly by Lophodermium pinastri which occurred 4-72 times more frequently than Lophodermium seditiosum; (e) frequencies of C. minus and C. ferruginosum were lower in the 0.5-yearold symptomless needles, increased in the symptomatic and symptomless 1.5-yearold needles and decreased after needle fall; (f) frequency of L. seditiosum was highest in 0.5-year-old needles; (g) frequency of L. pinastri increased with needle age whereas S. polyspora increased after needle fall; (h) lower frequency of L. pinastrii was associated with higher frequency of S. polyspora. It was concluded that Cyclaneusa needle cast in Poland may be caused by C. minus accompanied by C. ferruginosum, L. seditiosum, L. pinastrii and S. polyspora. Participation of Coniothyrium spp., Epicoccum nigrum, Pestalotiopsis spp. and Phoma spp. in the disease progress cannot be excluded.

The numbers of fungi: contributions from traditional taxonomic studies and challenges of metabarcoding

et al. 2022

View full text Add to dashboard Cite

The global diversity of fungi has been estimated using several different approaches. There is somewhere between 2–11 million estimated species, but the number of formally described taxa is around 150,000, a tiny fraction of the total. In this paper, we examine 12 ascomycete genera as case studies to establish trends in fungal species descriptions, and introduce new species in each genus. To highlight the importance of traditional morpho-molecular methods in publishing new species, we introduce novel taxa in 12 genera that are considered to have low species discovery. We discuss whether the species are likely to be rare or due to a lack of extensive sampling and classification. The genera are Apiospora, Bambusicola, Beltrania, Capronia, Distoseptispora, Endocalyx, Neocatenulostroma, Neodeightonia, Paraconiothyrium, Peroneutypa, Phaeoacremonium and Vanakripa. We discuss host-specificity in selected genera and compare the number of species epithets in each genus with the number of ITS (barcode) sequences deposited in GenBank and UNITE. We furthermore discuss the relationship between the divergence times of these genera with those of their hosts. We hypothesize whether there might be more species in these genera and discuss hosts and habitats that should be investigated for novel species discovery.

Cyclaneusma needle cast (CNC) is a needle disease which caused deterioration of vitality and reduction in the growth of pines. The disease is caused by the ascomycetous fungus Cyclaneusma minus, which has two well-described morphotypes; C. minus simile and C. minus verum. The distribution and host range of C. minus simile and verum was determined from needle samples and isolates collected throughout Slovakia from 2014 to 2020. Samples from 111 localities, 11 pine host species and 245 trees collected in different types of planting were analysed. It was found, that both morphotypes are present, but C. minus verum is predominantly responsible for CNC in urban and forest plantings in Slovakia. C. minus verum was positively detected in more than 88% of collected samples, whereas C. minus simile was only in four samples from three localities. Morphotype-specific primers were sufficiently sensitive even for new pine-host species. The host range of C. minus simile and C. minus verum was enriched worldwide. C. minus verum was observed in nine host species, whereas C. minus simile was identified only in one. Cyclaneusma niveum was also recorded and its presence was confirmed through DNA sequencing.
