Four individuals, representing 3 morphological species (identified morphologically as 2 dipterans, and 1 hemipteran, respectively), failed in multiple rounds of PCR amplifications.
Morphological species concept Another way that organisms can be classified is on the basis of morphology, or physical features.
This makes comparison of studies working on metabolites from medicinal polypores forming a morphological species complex especially critical and difficult.
For F. pinicola and P. betulinus, the morphological species concepts widely agree with the phylogenetic species delimitation.
From 1864 to 1935, museum-based taxonomists with no information on the natural biology of the fishes had no alternative but to apply morphological species definitions.
These analyses revealed three major lineages corresponding to the morphological species Lophodermium seditiosum and Lophodermium conigenum, fruiting on broken branches, and Lophodermium pinastri, fruiting on naturally fallen needles.
Until 2005, this IBT 9471 strain has been reclassified as T. brevicompactum on the basis of phylogenetic lineage within the morphological species T. brevicompactum and trichothecene production (Nielsen et al. 2005; Shentu et al. 2014a).
Although the mitochondrial genes resolved clear clades, several morphological species shared identical haplotypes and could not be separated, while some morphological species were clearly not monophyletic.
As a consequence, females present a serious issue to morphological species discovery and diagnosis.
We observed only one case of a morphological species being split into two (Rh.
