Holtermanniella

Holtermanniella Libkind, Wuczk., Turchetti & Boekhout, in Wuczkowski et al., International Journal of Systematic and Evolutionary Microbiology 61 (3) (2010)

Etymology: Holtermanniella named after Holtermannia, the name of the related sexual genus.

Diagnosis: Asexual fungi of the Tremellomycetes (Agaricomycotina, Basidiomycota), phylogenetically circumscribed from analysis of rDNA sequences and related to Holtermannia corniformis. With the exception of Holtermanniella mycelialis, mycelium is not produced. Colonies are cream to light yellow. Fermentation is absent. myo-Inositol and D-glucuronate are assimilated. Nitrate is not assimilated. Starch-like compounds are produced. At 30 °C, growth is weak. Diazonium blue B and urease reactions are positive. The type species is Holtermanniella takashimae Wuczkowski, Passoth, Andersson, Turchetti, Prillinger, Boekhout et Libkind.

Index Fungorum number: IF517033

Type species: Holtermanniella takashimae Wuczk., Passoth, A.-C. Andersson, Turchetti, Prillinger, Boekhout & Libkind, in Wuczkowski et al., International Journal of Systematic and Evolutionary Microbiology 61 (3) (2010)

Figure 1. Phylogenetic placement of the genus Holtermanniella and the order Holtermanniales using sequence analysis of the D1/ D2 region by the neighbour-joining method (Saitou & Nei, 1987). Bootstrap analysis was carried out with 1000 replicates (Felsenstein, 1985); only values above 50% are shown. The tree is drawn to scale, with branch lengths in the same units as those of the evolutionary distances used to infer the tree. Evolutionary distances were computed using Kimuras two-parameter method (Kimura, 1980) and are in the units of the number of base substitutions per site. Phylogenetic analyses were conducted in MEGA4 (Tamura et al., 2007). Accession numbers of D1/D2 sequences available in GenBank are included. Bar = 0.02 substitutions per site.
