“…Septal structure varies widely among groups (Fig. ), ranging from incomplete pseudosepta in some Blastocladiomycota (Meyer & Fuller, ) to highly sophisticated membranous barriers in Agaricomycetes (Orlovich & Ashford, ; Muller et al ., ; van Driel et al ., ; McLaughlin et al ., ). The distribution and function of these structures within the mycelium is also highly variable, and many lineages within the zygomycetous fungi lack them or restrict their presence to specific structures or senescent hyphae (Benny, Humber & Voigt, ; Redecker & Schüβler, ).…”

The question of how phenotypic and genomic complexity are inter‐related and how they are shaped through evolution is a central question in biology that historically has been approached from the perspective of animals and plants. In recent years, however, fungi have emerged as a promising alternative system to address such questions. Key to their ecological success, fungi present a broad and diverse range of phenotypic traits. Fungal cells can adopt many different shapes, often within a single species, providing them with great adaptive potential. Fungal cellular organizations span from unicellular forms to complex, macroscopic multicellularity, with multiple transitions to higher or lower levels of cellular complexity occurring throughout the evolutionary history of fungi. Similarly, fungal genomes are very diverse in their architecture. Deep changes in genome organization can occur very quickly, and these phenomena are known to mediate rapid adaptations to environmental changes. Finally, the biochemical complexity of fungi is huge, particularly with regard to their secondary metabolites, chemical products that mediate many aspects of fungal biology, including ecological interactions. Herein, we explore how the interplay of these cellular, genomic and metabolic traits mediates the emergence of complex phenotypes, and how this complexity is shaped throughout the evolutionary history of Fungi.

“…Higher fungi, i.e., zygomycetous fungi and Dikarya, lack motile cells as well as centrioles and the MTOC for nuclear division is a SPB, a derivative of the centrosome. SPBs have distinctive morphologies in those phyla and subphyla studied to date and have proved phylogenetically informative (Celio et al, 2006; McLaughlin et al, 2009, 2015). Spindle pole bodies may be globular or plaque‐ or disc‐shaped and form a middle piece that connects the duplicating SPBs (Roberson et al, 2010).…”

“…Nuclear division and SPB characters differ greatly between these two clades, most notably the cylindrical SPBs of Basidiobolus and Pandora (Entomophthoromycota), which are reminiscent of centrioles (Tanaka, 1970; Sun and Bowen, 1972; Gull and Trinci, 1974; Moorman, 1976; Heath and Rethoret, 1982; Butt and Beckett, 1984a, b; Murrin et al, 1984, 1988). The nuclear and SPB data can be viewed online in the AFTOL Structural and Biochemical Database (http://aftol.umn.edu/) (Celio et al, 2006; Kumar et al, 2013; McLaughlin et al, 2015). There are no data on SPB types or nuclear division for the other four clades (Glomeromycota, Kickxellomycotina, Mortierellomycotina, Zoopagomycotina), except for an incomplete report for the trichomycete Harpella (Kickxellomycotina) (Reichle and Lichtwardt, 1972).…”

Molecular techniques using fungal DNA barcoding (ITS) and other markers have been key to identifying the biodiversity of different geographic areas, mainly in megadiverse countries. Here, we provide an overview of the fungal diversity in Brazil based on DNA markers of phylogenetic importance generated since 1996. We retrieved fungal sequences of ITS, LSU, SSU, tef1-α, β-tubulin, rpb1, rpb2, actin, chitin synthase, and ATP6 from GenBank using different field keywords that indicated their origin in Brazil. A total of 19,440 sequences were recovered. ITS is the most representative marker (11,209 sequences), with 70.1% belonging to Ascomycota, 18.6% Basidiomycota, 10.2% unidentified, 1.1% Mucoromycota, two sequences of Olpidium bornovanus (Fungi incertae sedis), one sequence of Blastocladiomycota (Allomyces arbusculus), and one sequence of Chytridiomycota (Batrachochytrium dendrobatidis). Considering the sequences of all selected markers, only the phyla Cryptomycota and Entorrhizomycota were not represented. Based on ITS, using a cutoff of 98%, all sequences comprise 3047 OTUs, with the majority being Ascomycota (2088 OTUs) and Basidiomycota (681 OTUs). Previous numbers based mainly on morphological and bibliographical data revealed 5264 fungal species from Brazil, with a predominance of Basidiomycota (2741 spp.) and Ascomycota (1881 spp.). The unidentified ITS sequences not assigned to a higher taxonomic level represent 1.61% of all ITS sequences sampled and correspond to 38 unknown class-level lineages (75% cutoff). A maximum likelihood phylogeny based on LSU illustrates the fungal classes occurring in Brazil.
