TOMŠOVSKÝ M., JANKOVSKÝ L. (2007): DNA sequence analysis of extraordinary fruiting specimens of Fuscoporia torulosa (Phellinus torulosus) on Pyrus spp. [Fuscoporia, Phellinus, DNA, ITS region, fructification] Czech Mycology 59(1): 91-99 (published: 28th June, 2007)
abstract
Fuscoporia torulosa (Phellinus torulosus) is a typical polypore of thermophilous forests in Central Europe. In most cases the fungus forms basidiocarps on base or roots of various host trees (mainly Quercus), but sometimes the basidiocarps appear on stem heights of approx. 2 m. This extraordinary fructification pattern seems to be restricted to Pyrus as a host. The aim of this study was to compare such basidiocarps with those growing on the base of oak trees according to their DNA sequences to reveal a possible process of speciation. The so-called ITS region of nuclear ribosomal DNA was chosen for the study. Results did not reveal any significant differences between basidiocarps with the distinct fructification pattern, so all examined specimens belong to one species. The relation of Fuscoporia torulosa to Phellinus senex is discussed.
AMOOPOUR M., GHOBAD-NEJHAD M., KHODAPARAST S.A. (2016): New records of polypores from Iran, with a checklist of polypores for Gilan Province. [fungi, hyrcanian forests, poroid basidiomycetes] Czech Mycology 68(2): 139-148 (published: 27th September, 2016)
abstract
As a result of a survey of poroid basidiomycetes in Gilan Province, Antrodiella fragrans, Ceriporia aurantiocarnescens, Oligoporus tephroleucus, Polyporus udus, and Tyromyces kmetii are newly reported from Iran, and the following seven species are reported as new to this province: Coriolopsis gallica, Fomitiporia punctata, Hapalopilus nidulans, Inonotus cuticularis, Oligoporus hibernicus, Phylloporia ribis, and Polyporus tuberaster. An updated checklist of polypores for Gilan Province is provided. Altogether, 66 polypores are known from Gilan up to now.
INSUMRAN Y., KLINHOM U., PRAMUAL P. (2012): Variability of internal transcribed spacer ribosomal DNA sequences of Fuscoporia gilva and Fuscoporia sp. in Thailand. [Fuscoporia, Internal Transcribed Spacer, medicinal mushroom, Hymenochaetales] Czech Mycology 64(1): 55-64 (published: 2nd July, 2012)
abstract
The objectives of this study were to examine genetic variation based on the ITS region of the ribosomal RNA gene sequences of Fuscoporia sp. and F. gilva from Thailand. Considerable levels of genetic variation were found in the Thai samples. The mean intraspecific genetic divergence was 5.74 % for Fuscoporia sp. and 5.33 % for F. gilva, indicating that they might be composed of several genetically distinct species. Phylogenetic analyses revealed that Fuscoporia sp. from Thailand was genetically related to F. callimorpha and F. senex. However, comparisons of the morphological characters and the level of genetic divergence indicated that they were different taxa. Two divergence lineages among Thai Fuscoporia sp. associated with host species preference were found. This finding could indicate the role of host association in genetic divergence and probably speciation. Fuscoporia gilva from Thailand was clustered with conspecific species from other geographic regions. Nonetheless, levels of genetic differentiation are highly consistent with their divergent phylogenetic clades. This indicates that specimens from Thailand might represent genetically distinct species. Further study using other genes and an in-depth morphological analysis would be needed to clarify the species status of these important mushrooms.
