Xenasmatella sp. "NJ-01"
Basidiomycota: Agaricomycotina: Agaricomycetes: Xenasmatales: Xenasmataceae: Xenasmatella
Introduction
Description
Ecology:
Basidioma: Fresh basidioma cream and greyish bluish in color, very thin (up to 150 µm in thickness) with a farinaceous to chalky consistency and smooth to punctate or granulose configuration; dried basidioma tannish and inconspicuous; no rhizomorphs or codons present.
Chemical reactions: Not evaluated on fresh basidioma, but 5% KOH reacts black on the dried basidioma (similar to the wood substrate, but the latter returns to its original color upon drying whereas the hymenium retains its darkened color).
Spore print: White.
Hyphal system: Monomitic, clamp connections present, width (1.4) 1.7–3.0 (3.2) µm (n = 10).
Basidia: Spores abundant but mature basidia difficult to find; pleurobasidia squat, pedunculate, clavate, or cylindrical in shape with four sterigmata up to 5 µm long; length (7.5) 8.3–11.9 (13.7) µm, width (4.8) 5.2–6.3 (6.8) µm, x̄ = 10.1 ✕ 5.8 µm (n = 10).
Basidiospores: Subglobose to ellipsoid, ornamented with prominents warts or spines, inamyloid; length (4) 4.2–4.7 (5.2) µm, width (3.3) 3.5–4.1 (4.4) µm, x̄ = 4.5 ✕ 3.8 µm; Q (1) 1.1–1.3 (1.4), x̄ = 1.2 (n = 30).
Sterile structures: Absent.
Sequences: ITS rDNA (ON364098), LSU rDNA (ON369551).
Notes: All measurements taken in 5% KOH stained with phloxine.
