Pluteineae Aime, Dentinger & Gaya subord. nov.

Name registration: IF551140

Type family: Pluteaceae Kotl. & Pouzar, Ceska Mykol. 26: 218 (1972).

Basidiomata agaricoid, mostly fleshy, the majority with angiocarpic development and free lamellae. Hyphae monomitic; clamp connections present or absent; non-amyloid. Basidia 2–4 spored; basidiospores hyaline or with pink pigmentation, the vast majority smooth, some amyloid. Cystidia often present. Hymenophoral tramal regular, bilateral or inverse.

Representative families: Amanitaceae R. Heim ex Pouzar , Pluteaceae .

Notes: Pluteineae contains most angiocarpic species of Agaricales , although some species (primarily members of Pluteus ) do not develop veils. Most Amanitaceae are ectomycorrhizal, except Aspidella spp. , and most Pluteaceae are saprobes. This lineage was first recovered with bootstrap support in Moncalvo et al. (2002) but without a formal clade designation. Limnoperdonaceae may also belong here ( Matheny et al., 2006). This group was not supported in the ASTRAL tree ( Fig. 4 ) and the tree based on ranked genes using RF distances (see Supporting information, Fig. S2C ), and some previous studies have not recovered Pluteaceae with Amanitaceae ( Bodensteiner et al., 2004) or Volvariella within Pluteaceae ( Justo et al., 2011) , and further investigation is warranted.

Figure 4. Consensus trees of individual gene trees. Left: extended majority-rule consensus (MRE) tree based on bootstrap replicates of individual gene analyses for all genes with no missing taxa (N = 175). Numbers above branches are internode certainty (IC) and internode certainty all (ICA) values for all individual bootstrap trees compared to the MRE tree. Numbers in bold represent nodes that are not present in the ASTRAL tree (right). Right: coalescentbased consensus tree recovered by ASTRAL using 208 single gene maximum likelihood trees from RAXML analysis. Numbers in bold above branches are IC, ICA values for all individual bootstrap trees that are not present in the MRE tree (left). Numbers below branches are bootstrap supports based on single gene bootstrap analysis (100 replicates each).
