Descolea quercina (Bolbitiaceae), a new species from moist temperate forests in Pakistan (original) (raw)

First records of Bolbitius coprophilus (Agaricales, Bolbitiaceae) from Pakistan

2022

In efforts to record fungal biodiversity of Pakistan, we collected specimens of the genus Bolbitius Fr. from two arid to semi-arid localities in Punjab Province. On the basis of morphological evidence and ITS-nrDNA sequence data, our materials are identified as B. coprophilus (Peck) Hongo. These specimens were found to be identical in morphological characteristics to other B. coprophilus collections from throughout the world. Based on a phylogenetic analysis, sequences from our material clustered within the B. coprophilus clade, which is consistent with our morphological findings. Our three records of B. coprophilus from Pakistan are the first from the country. The distribution of B. coprophilus is discussed and a morphological comparison with closely related taxa is provided.

Hortiboletus kohistanensis (Boletaceae), a new bolete species from temperate and subalpine oak forests of Pakistan

Phytotaxa, 2019

Hortiboletus kohistanensis is described as a new species from the moist temperate and subalpine oak forests of Pakistan after detailed morphological and phylogenetic analyses as well as comparison with related taxa. This oak-associated species is morphologically distinguished from allied taxa by an areolate pileus surface and whitish stipe base. It is also phylogenetically distinct from H. indorubellus, the most closely related species, from India.

Phylogenetic relationships of Deschampsia antarctica (Poaceae): Insights from nuclear ribosomal ITS

Plant Systematics and Evolution, 2006

Deschampsia antarctica E. Desv. is the only monocot in the Antarctic floristic zone. We evaluated the phylogenetic relationships of Deschampsia antarctica to other grasses using parsimony as the optimality criterion. Five different sets of gap, transversion and transitions costs were explored to analyze the effect of parameter choice on the phylogenetic results. Both internal transcribed spacers (ITS1 and ITS2) and the 5.8S subunit of nuclear ribosomal DNA were included in the analysis. A total of 43 species were analyzed including seven species of Deschampsia. Deschampsia antarctica forms a well supported group with five species of Deschampsia. Deschampsia does not appear monophyletic as D. flexuosa (L.) Trin. is not included in this clade. The clade to which D. antarctica belongs is sister to some Aveneae in all analyses. This study is the first contribution that evaluates the phylogenetic position of D. antarctica in relation to other species of Deschampsia.
