“…Because differences in the profiles of volatiles produced by different phenotypes reflect changes on the genetic level, chemosystematics based on volatile organic compounds could be useful to taxonomists and ecologists for better identification and classification of fungi in this group. Studies have shown that cryptic species within a species complex differ significantly in their volatile profiles (Ludwiczuk et al 2013; Wawrzyniak et al 2014), and so by using such methods it should be possible to differentiate among the cryptic species previously described in the G. clavigera complex (Alamouti et al 2011). …”

Conifer bark beetles attack and kill mature spruce and pine trees, especially during hot and dry conditions. These beetles are closely associated with ophiostomatoid fungi of the Ascomycetes, including the genera Ophiostoma, Grosmannia, and Endoconidiophora, which enhance beetle success by improving nutrition and modifying their substrate, but also have negative impacts on beetles by attracting predators and parasites. A survey of the literature and our own data revealed that ophiostomatoid fungi emit a variety of volatile organic compounds under laboratory conditions including fusel alcohols, terpenoids, aromatic compounds, and aliphatic alcohols. Many of these compounds already have been shown to elicit behavioral responses from bark beetles, functioning as attractants or repellents, often as synergists to compounds currently used in bark beetle control. Thus, these compounds could serve as valuable new agents for bark beetle management. However, bark beetle associations with fungi are very complex. Beetle behavior varies with the species of fungus, the stage of the beetle life cycle, the host tree quality, and probably with changes in the emission rate of fungal volatiles. Additional research on bark beetles and their symbiotic associates is necessary before the basic significance of ophiostomatoid fungal volatiles can be understood and their applied potential realized.Electronic supplementary materialThe online version of this article (doi:10.1007/s10886-016-0768-x) contains supplementary material, which is available to authorized users.

Aneura pinguis is known as a species complex with several morphologically indiscernible species, which are often reproductively isolated from each other and show distinguishable genetic differences. Genetic dissimilarity of cryptic species may be detected by genomes comparison. This study presents the first complete sequences of chloroplast and mitochondrial genomes of six cryptic species of A. pinguis complex: A. pinguis A, B, C, E, F, J. These genomes have been compared to each other in order to reconstruct phylogenetic relationships and to gain better understanding of the evolutionary process of cryptic speciation in this complex. The chloroplast genome with the nucleotide diversity 0.05111 and 1537 indels is by far more variable than mitogenome with π value 0.00233 and number of indels 1526. Tests of selection evidenced that on about 36% of chloroplast genes and on 10% of mitochondrial genes of A. pinguis acts positive selection. It suggests an advanced speciation of species. The phylogenetic analyses based on genomes show that A. pinguis is differentiated and forms three distinct clades. Moreover, on the cpDNA trees, Aneura mirabilis is nested among the cryptic species of A. pinguis. This indicates that the A. pinguis cryptic species do not derive directly from one common ancestor.

Aneura pinguis is a thalloid liverwort species with broad geographical distribution. It is composed of cryptic species, however, the number of cryptic species within A. pinguis is not known. Five cpDNA regions (matK, rbcL, rpoC1, trnH-psbA and trnL-trnF) and the entire nuclear ITS region were studied in 130 samples of A. pinguis from different geographical regions. The relationships between the cryptic species of A. pinguis, A. maxima and A. mirabilis were analyzed. All of the examined samples were clustered into 10 clades corresponding to 10 cryptic species of A. pinguis (marked A to J). Aneura mirabilis and A. maxima were nested among different cryptic species of A. pinguis, which indicates that A. pinguis is a paraphyletic taxon. Subgroups were found in cryptic species A, B, C and E. As single barcodes, all tested DNA regions had 100% discriminant power and fulfilled DNA barcode criteria for species identification; however, the only combination detected in all subgroups was trnL-trnF with trnH-psbA or ITS2. The distances between cryptic species were 11- to 35-fold higher than intraspecific distances. In all analyzed DNA regions, the distances between most pairs of cryptic A. pinguis species were higher than between A. maxima and A. mirabilis. All cryptic species of A. pinguis clearly differed in their habitat preferences, which suggests that habitat adaptation could be the main driving force behind cryptic speciation within this taxon.
