Reciprocal specialization and vertical symbiont cotransmission are thought to promote a pattern of largely synchronous coevolutionary diversification in attines. Here we test this hypothesis by inferring the first time-calibrated multigene phylogeny of the lepiotaceous attine cultivars and comparing it with the recently published fossilanchored phylogeny of the attine ants. While this comparison reveals some possible cases of synchronous origins of ant and fungal clades, there were a number of surprising asynchronies. For example, leafcutter cultivars appear to be significantly younger than the corresponding ant genera. Similarly, a clade of fungi interacting with primitive fungus-gardening ants-thought to be ancestral to the more derived leaf-cutter symbionts-appears instead to be a more recent acquisition from free-living stock. These macroevolutionary patterns are consistent with recent population-level studies suggesting occasional acquisition of novel cultivar types from environmental sources and horizontal transmission of cultivars between different ant species. Horizontal transmission events, even if rare, appear to form loose ecological connections between diffusely coevolving ant and fungus lineages that permit punctuated changes in the topology of the mutualistic ant-fungus interaction network.

“…The section Xanthodermatei was originally thought to be a monophyletic group based on its ITS sequence data Challen et al 2003;Geml et al 2004;Kerrigan et al 2005;Thongklang et al 2014;Zhao et al 2011). However, based on the most recent study on Agaricus using multigene sequences, the Xanthodermatei section has been split into two sections: Xanthodermatei and Hondenses .…”

“…Xanthodermatei by their more persistent color change, positive Schäffer reaction, anise seed or almondlike odors, and lack of toxic compounds (Parra 2008). Molecular studies using ITS sequence data from samples from Europe and North America indicate that this section is monophyletic Challen et al 2003;Geml et al 2004;Kerrigan et al 2005). Later phylogeny studies of Agaricus using the ITS sequences of specimens from temperate and tropical areas also indicated that this section is a monophyletic group with 85 supporting BS, composed of two well-supported clades, which are represented by A. xanthodermus and A. hondensis Murrill (1912: 296), respectively (Zhao et al 2011).…”

Specimens of Agaricus sections Xanthodermatei and Hondenses were collected in Tibet and the surrounding areas. All specimens were morphologically described and subjected to molecular phylogenetic analysis of the ITS and combined ITS, LSU and tef-1α sequence data using Bayesian and Maximum Likelihood methods. Twelve species were identified in this study, eleven of which were new species and one of which was identified in China for the first time. All of the identified species are described and illustrated with photo plates.

“…4 Botanically, Agaricus is a genus belonging to the family Agariaceae, 5 and is generally described as having small to large fruit bodies with white, yellow or brown pileus; free lamellae that are pallid or pinkish when young, later becoming chocolate brown; and also dark-brown, smooth basidiospores. 6 Phytochemically, the general gross composition of mushrooms is water (90%), protein (2-40%), fat (2-8%), carbohydrates (1-55%), fiber (3-32%) and ash (8-10%). The active contents can be isolated from fruiting bodies, pure culture mycelia and culture filtrate.…”
