“…Previous work on mycophagy and EMF has focused almost exclusively on hypogeous fungi and small mammals (Luoma et al, 2003). Hypogeous fungi produce odors that attract rodents and marsupials that dig up the sporocarps, consume them and disperse their spores when they defecate (Thiers, 1984;Johnson, 1996;Luoma et al, 2003). Spores in feces are viable and have been shown to successfully yield mycorrhizas on seedlings (Kotter & Farentinos, 1984;Claridge et al, 1992;Colgan & Claridge, 2002).…”

Ectomycorrhizal ecology under primary succession on coastal sand dunes: interactions involving Pinus contorta, suilloid fungi and deer

2005

Summary• Ectomycorrhizal fungi (EMF) are critical for pine establishment under primary succession. The species of EMF supporting primary successional pine seedlings on coastal sand dunes and mechanisms for their establishment were investigated.• Fungi were identified from ectomycorrhizal roots using molecular techniques. Field seedlings were collected from forested and nonforested zones. Laboratory seedlings were grown in soils collected from the same zones, and in sterile soils inoculated with fresh and 1-yr-old dry deer fecal pellets.• Suilloid fungi were frequently observed on all seedlings. A diverse group of fungi was available to seedlings in forested zones. A less diverse group of fungi was available to field seedlings in nonforested zones and all laboratory bioassay seedlings. Deer fecal inoculant yielded an average of two EMF per seedling. Both Suillus and Rhizopogon species dominated seedlings inoculated with fresh deer feces, but only Rhizopogon species dominated seedlings inoculated with 1-yr-old feces.• Suilloid fungi are dispersed by deer, produce resistant spore banks and are the principle fungi supporting seedlings on the sand dunes.

“…Molecular systematics studies have revealed that gasteromycetes have independently evolved many times within the basidiomycetes during the adaption of environmental selective pressures, such as arid conditions, dispersal vectors, and unknown mechanisms ( Fig. 1; Bruns et al 1989;Hibbett et al 1997;Peintner et al 2001;Binder and Bresinsky 2002;Binder et al 2006;Henkel et al 2010), as were suggested by Oberwinkler (1977Oberwinkler ( , 1978Oberwinkler ( , 1985, Thiers (1984) and many others. It was suggested that the evolution of the sequestrate state to be irreversible (Hibbett 2004.…”

“…The gasteromycetes were often treated a single group, although some, such as the secotioid taxa, have anatomical similarities to certain agarics and boletes, and, as a result, were supposed to be related to agarics and boletes respectively. However, views were in conflict as regards to the direction of the evolutionary process (Singer and Smith 1960;Heim 1971;Thiers 1984;Singer 1986). Oberwinkler (1977Oberwinkler ( , 1978, Thiers (1984) and others argued that it was more likely that sequestrate (secotioid or gasteroid) basidiomycetes were derived repeatedly and convergently, and should not be regarded as a single natural group.…”

A brief survey towards an understanding of evolution of Basidiomycota in the last five decades is given. Between 1960-1990 studies were based mainly on morphology, subcellular structure, biochemistry, physiology and ecology. In the last 20 years, molecular methods have revolutionized the study of taxonomy, systematics, phylogeny, biogeography, population and microevolutionary processes in basidiomycetes. A fundamental improvement in the understanding of evolution of basidiomycetes has been achieved. It is anticipated that numerous new taxa at different taxonomic levels will be recognized based on integrated approaches, and new data will soon provide fascinating insights into the origin, evolution and biogeography of basidiomycetes in the coming years.

“…Some of sequestrate fungi have secotioid basidiomes. Secotioid fungi are known to the phylum Basidiomycota and comprise fungi where the margin of the pileus does not break free from the stipe (the hymenophore remaining enclosed) lamellae are convoluted and anastomosed, and basidiospores are not ballistosporic (Thiers 1984, Kirk et al 2008.…”

Setchelliogaster tenuipes is ectomycorrhizal species with Eucalyptus spp. and currently occurring throughout the world, introduced from Australasia. In South America, it is known from Argentina, Brazil, Uruguay and Chile. Some of the main features of S. tenuipes are the reddish brown basidiomes, presence of stipe, shape of cystidia and peridium structures. The aim of the study is to report the genetic diversity of Setchelliogaster tenuipes (Setch.) Pouzar in Brazil, as well as, in the world distribution. It was presented morphological and phylogenetic notes of this species sampled in Brazil.
