Atraporiella is a monotypic fungal genus in the family Steccherinaceae. It contains the crust fungus Atraporiella neotropica, known only from Belize.
Taxonomy
Atraporiella is a
monotypic genus, containing the single
polypore species
Atraporiella neotropica, described as new to science by Norwegian mycologist
Leif Ryvarden in 2007. This
crust fungus is found in
Belize, where it grows on decomposing wood. The type collection was made in the
Cayo District in November 2001.
Molecular analysis suggests that the genus belongs in the family Steccherinaceae.
Description
The
basidiocarp of
Atraporiella neotropica is in the form of a small crust fungus, with length and width dimensions of up to , and a thickness of up to . When fresh, the pore surface is white, but it readily stains dark brown to black when bruised. The pores are angular, numbering about five to six per millimetre.
Atraporiella has a monomitic
structure (containing only generative hyphae), and these hyphae are highly branched, 3–6
micrometre, and have
. The
basidiospore are
ellipsoid, thin-walled, smooth,
hyaline (translucent), and do not react with Melzer's reagent. They measure 3–3.5 by 1.2–1.4 μm.
