Mushroom-forming fungi (Agaricomycetes) have the greatest morphological diversity and complexity of any group of fungi. They have radiated into most niches and fulfil diverse roles in the ecosystem, including wood decomposers, pathogens or mycorrhizal mutualists. Despite the importance of mushroom-forming fungi, large-scale patterns of their evolut...

Gyroporus (Gyroporaceae, Boletales) is a highly diverse genus of poroid ectomycorrhizal mushrooms with a nearly worldwide distribution. Previous attempts to unravel the diversity within this genus proved difficult due to the presence of semicryptic species and ambiguous results from analysis of ribosomal RNA markers. In this study, we employ a comb...

... The species are ecologically important because most are considered to be mycorrhizal with woody plants, whilst they are important economically because some species are edible whilst others are poisonous (Cui et al. 2018). The genus has been monographed in Australia by Reid (1980) and Wood (1997), whilst additional mushroom species have been described and taxonomic clarifications made by Miller (1991Miller ( , 1992, Grgurinovic (1997), Davison (2011), , Davison et al.

... In addition to the chronosequence studies that compare fungal communities on sites of different fire history (Table 1), inventories of fungi from individual sites of known time since fire could be relevant when considering the effects of fire on fungi. Examples of such inventories come from repeated sampling for fruit-bodies of various groups of macrofungi on Mt Wellington in Tasmania, which was last burnt in 1967 (Ratkowsky and Gates 2002;Ratkowsky 2004, 2005;Trappe et al. 2008). Such inventories have the potential to contribute to the pool of knowledge about fungi in different vegetation types of particular fire histories, but at present the information available is too limited to make meaningful comparisons. ...

... The first species of this group Tylopilus balloui (Peck) Singer was described by C.H. Peck in 1912 (as a Boletus) from North America [80]. The generic recognition of T. balloui was ambiguous as an extension of either Gyrodon, Rubinoboletus and Gyroporus [81]; however, phylogenetic studies confidently place it in a core Tylopilus clade [63,66,[82][83][84]. This species was reported from various regions of the tropical and subtropical areas, and it was considered that T. balloui sensu lato has a very wide distribution with some morphological variability for each region. ...

... In contrast, the mycota has not received the same degree of attention in conservation and restoration of any eucalyptdominated ecosystem, despite its importance in plant and animal nutrition and nutrient cycling through leaf and woody litter decomposition (Bougher and Tommerup, 1996;O'Connell and Grove, 1996;Bougher and Tommerup, 2003). E. marginata occurs on relatively nutrient-poor soils, thus nutrient access through mycorrhizal associations is likely to be of particular importance to establishment and survival of the plant community (Churchward and Dimmock, 1989). ...
