Melzers reagent

layers 1 and 3 wall la yer stained with Melzer‟s reag

Melzer’s reagent is an iodine solution used in the study of the white spored Hymenomycetes, the asci of Ascomycetes, and other parts of fungi. However, Melzer’s reagent contains chloral hy- drate, a medically controlled substance, and therefore is hard to get. Sexual structures were microscopically observed in water, 10% KOH, and Melzer’s reagent, as determined by Ju and Rogers . The color codes appearing in this article refer to Rayner [ 23 ]. In the text, the following abbreviations are used: KOH = 10% potassium hydroxide, n = number of ascospores measured from a given number of specimens, M ...

A "tooth" of the hydnoid fungus Auriscalpium vulgare, stained with Melzer's reagent A 5–10 spores of each spore type were mounted in polyvinyl-lacto-glycerol (PVLG) and PVLG-Melzer reagent (1:1, v:v) on a glass slide; the spores in Melzer reagent were crushed in order to observe staining of different layers of spore wall. Spores were examined using a compound microscope (Olympus AX70) with Nomarski optics. ...Melzer’s reagent should be used instead of Lugol’s or iodine in spore identifi cation.

The reagent is then made to 1000 ml by the addition of 600ml distilled water. The formula can be adjusted to suit the performance parameters. Sample (1% tyrosine) Materials Required. Test tubesMicroscopic features, measurements and drawings were made from slide preparations stained with Cotton Blue or Melzer's reagent. Spores were measured from sections cut from the tubes (Cui et al. 2008). In presenting the variation in the size of the spores, 5% of measurements were excluded from each end of the range, and are given in parentheses.Concerning the spore walls, as mentioned above, most Acaulospora species present three walls, with a Melzer reaction and a "beaded" layer, with few exceptions, as is the case with A. colliculosa, for which the inner wall is smooth, not beaded, and shows an absence of Melzer's reagent.In middle aged spores, it may or may not expand slightly, but it usually reacts with Melzer's reagent (in PVLG-M) to become pink or red. In what seem to be fully mature spores, this component remains evident, but does not always react to Melzer's reagent. In very old spores, this component disappears, hence its designation as evanescent.Download scientific diagram | Microscopic photographs of Cordyceps militaris, a) Perithecia in Melzer's reagent (MLZ); b) perithecium in Lugol's solution (IKI); c) asci in IKI; d) asci in MLZ; e ...Lugols Iodine Solutions.

Spore observations should be made in a Melzer's reagent mount to assess whether the spores are amyloid or not. While most mycenoid species have amyloid spores, they are not as strikingly amyloid as, for example, the amyloid spores of some Amanita species--and the amyloidity usually fades as the spores age and mature, so that many spores in a ...Melzer's reagent. Chloral hydrate is an ingredient used to make Melzer's reagent, an aqueous solution that is used to identify certain species of fungi. The other ingredients are potassium iodide, and iodine. Whether tissue or spores react to this reagent is vital for the correct identification of some mushrooms. SafetyMelzer's reagent most often informally known simply as Melzer's is a stain and wet mount used to study the cellular structure of fungi in mycology to help assist with their identification.
