Coltriciella multipileata is described here as a new species from Mexico. The species grow on soils in open areas at the vicinity of living trees of Pinus patula, and its known only from the Parque Recreativo Los Colomos, Jalisco. The phylogenetic analysis based on partial nuclear 28S ribosomal DNA sequences, recovered Coltriciella multipileata as sister group with a specimen reported as ectomycorrhizal, and closely related with other two species that are considered saprophitic. According with our preliminary analysis of character states reconstruction, the ectomycorrhizal condition appeared early in the Coltriciella clade, with a high rate of transitions between ectomycorrhizal and saprophitic conditions. A key for species similar to Coltriciella multipileata is presented.

In this study, phylogenetic analysis of Turkish Conringia (Brassicaceae) species was conducted based on nuclear ribosomal DNA (nrITS) and chloroplast DNA (trnL-F) sequences. In addition, the relationships between the sequences of some Brassicaceae family species retrieved from NCBI, and Conringia species were documented. All of the plant specimens were collected at their flowering and vegetation periods from different regions of Turkey, and brought to the laboratory. Total genomic DNA was extracted using the GeneMark kit. In PCR analyses, ITS4 and ITS5A primers were used for the amplification of the nrITS region, while the trnLe and trnLf primers were used for the cpDNA trnL-F region. The DNA sequences obtained were then edited using BioEdit and FinchTV, and analyzed using MEGA 6.0 software. Neighbor joining (NJ) and bootstrap trees were constructed in order to identify the relationships among Conringia taxa. The nrITS sequences ranged between 573 and 672 nucleotides, while the trnL-F sequences ranged between 346 and 764 nucleotides. The divergence values of nrITS sequences differed between 0.177 and 0.00 and divergence values of trnL-F sequences differed between 0.902 and 0.00. NJ tree generated using nrITS and trnL-F sequences consisted of two clades. In trees generated with both the nrITS and trnL-F sequences, C. orientalis, C. grandiflora and C. austriaca appeared within the same group. In addition, according to the phylogenetic analysis results obtained with other Brassicaceae species, it is revealed that the Conringia genus is polyphyletic.

We characterized 23 isolates of the entomopathogenic fungus Aschersonia spp. from Mexico, Brazil, Guyana, Trinidad, Venezuela, Columbia, Florida, Malaysia, Thailand, Japan, Philippines, Java and South India using RAPD markers. The data were used to compute the genetic variability and to reconstruct the phylogeny of the genus Aschersonia. Relative genetic distances varied from 0.018 (between isolates Aa2 and Ap2) to 0.445 (between isolates A1 and At1). In the constructed phylogenetic tree, isolates were clustered according to their geographical origin. We determined partial 26S ribosomal DNA sequences of five Aschersonia isolates (A28, A31, Ai1a, Ai2b – Aschersonia spp.; and Ap1– Aschersonia placenta) and used them for phylogenetic analysis. Three of the tested isolates were not distinguishable. The tree constructed indicated that isolates Ai1a and Ai2b belong to species distinct from A. placenta and A. aleyrodis.
