Hymenotorrendiella P. R. Johnst., Baral & R. Galan 2014, gen. nov.
No full textHymenotorrendiella P.R. Johnst., Baral & R. Galán, gen. nov. Registration identifier: IF550522 Differs from Torrendiella by the Hymenoscyphus - or Calycina - type ascus apex structure and the contents of the living paraphyses comprising numerous globose vacuolar bodies. Type:— Hymenotorrendiella eucalypti (Berk.) P.R. Johnst., Baral & R. Galán Etymology:—refers to the phylogenetic position of this Torrendiella -like genus in a clade containing the type species of Hymenoscyphus. Apothecia 0.2–5 mm diam., with short to long stalk, disc whitish to cream or grey, exterior concolorous or light to black-brown, receptacle and often also stalk with dark brown setae. Asci 8-spored, apex distinctly conical, apical ring staining blue in IKI (without KOH, type bb), either of the Hymenoscyphus - type: forming a thin-walled tube restricted to the lower part of the apical thickening or extending to the apex, or sometimes of the Calycina - type: tube apically thicker-walled and here laterally extending, ring basally not distinctly projecting, not forming an apical chamber; base arising from croziers or simple septa (without basal protuberance). Ascospores non-septate when mature, hyaline, straight or slightly, rarely medium curved, narrowly to broadly ellipsoid, fusoid, fusiform, or lemon-shaped (homopolar), containing in the living state some large and a few or many small oil drops (high lipid content), with a thin sheath around the entire spore that separates after discharge, sometimes with polar mucilaginous caps, overmature non-septate, spores sometimes budding ellipsoid microconidia (H. madsenii). Paraphyses cylindrical, straight, not or only slightly enlarged at the apex, containing many globose, small or large, strongly refractive, hyaline vacuolar bodies (living state), mainly in the terminal cell. Ectal excipulum comprising three layers: outer layer (ec1) one-layered, of meandering hyphae, encrusted with olivaceous to red-brown wall pigment, or hyaline and smooth; central layer (ec2) of prismatic or long-cylindrical cells, very slightly to strongly gelatinized, hyaline, rarely pale brown and encrusted; inner layer (ec3) of long-cylindrical hyphae, pale to bright brown, not or ± distinctly encrusted. Setae with dark brown, 1–3.5 µm thick wall, rooting or superficial, base unbranched or T- to L-shaped. Habitat:—developing on fallen leaves or dead wood, or bark of angiosperms. FIGURE.

Synthesis of gold nanosheets with controlled morphology by combining a natural amino acid with high-frequency ultrasound
No full textIn this study, we report on the formation of gold nanosheets with different morphologies using a naturally occurring amino acid, viz, tryptophan, as a reducing and capping agent at ambient conditions. The importance of in situ-oxidized tryptophan for promoting anisotropic growth of gold (Au) nuclei to form two-dimensional gold nanosheets is demonstrated. Furthermore, we investigated the effect of high frequency ultrasound (490 kHz) and tryptophan to fabricate ultrathin gold nanosheets with controlled morphologies (triangular and polygonal shapes), without using any other reagents/stabilizers. The size of gold sheets (200 nm to micrometer range) can be controlled by tuning the experimental conditions. A possible mechanism for the formation of well-defined gold nanostructures with different morphologies is provided. High frequency sonication leads to the simultaneous dimerization of tryptophan and Au reduction, and we show that the interaction of tryptophan dimers with Au nuclei plays an important role in the formation of gold sheets. The sonochemically synthesized AuNSs displayed superior catalytic activity in the reduction of 4-nitrophenol to 4-aminophenol with a specific rate constant of 1.96 x 10(3) s(-1) per unit gram of active catalyst and with excellent recyclability
