Possible Confusion . It is hard to confuse with other species. Oak bracket (Pseudoinonotus dryadeus) might look similar for some, but it is a root parasitic species, mostly growing around the roots of an oak (Quercus) or a Chestnut (Castanea).It is a common species and much larger than alder bracket. Mensularia nodulosa, pictured, grows on beech (Fagus), and it is really rarely recorded and ...Melzer's reagent is part of a class of iodine/potassium iodide (IKI)-containing reagents used in biology; Lugol's iodine is another such formula. Reactions Edit.Melzer's reagent (also known as Melzer's iodine reagent, Melzer's solution or informally as Melzer's) is a chemical reagent used by mycologists to assist with the identification of fungi, and by phytopathologists for fungi that are plant pathogens. A "tooth" of the hydnoid fungus Auriscalpium vulgare, stained with Melzer's reagent Melzer'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. It's made up of equal parts choral hydrate and a Lugol's solution. Melzer's can be a bit troublesome to attain in that choral hydrate is a DEA ...They are amyloid, meaning they will absorb iodine when stained with Melzer's reagent. WikiMatrix The smooth spores are oval to ellipsoid, hyaline (translucent), non-amyloid (meaning they do not absorb iodine from Melzer's reagent ), and typically measure 6.5-7.5 by 4.5-5.5 μm.

Melzer's reagent or cotton blue was used, and Hertwig's solution was not. For the first three samples (15 slides), diet components in 25 systematically selected fields of view per slide were recorded under a magnification of 500X. Components were categorized as fungal spores (to genus), fungal tissue, and plant tissue. ...

Arbuscular mycorrhizae are an intimate associations between 92% of the plant families [41] and fungi of the phylum Glomeromycota [30].Arbuscular-mycorrhizal fungi (AMF) probably played a significant historical role in the process of land colonization by plants [28].AMF not only improve the growth of plants by increasing the uptake of available phosphorus and other nonlabile ...

Stains are necessary for many aspects of identification. For spores, measurements are best made in water, but you should have Melzers reagent for observing ornamentation on Russula and Lactarius spores, as well as seeing the two types of iodine reaction, either amyloid (grey/blue) or dextrinoid (brown)

The article reports four species of Pezizaceae, Peziza echinospora, P. limnaea, P. nivalis and P. sublaricina, newly recorded for the Republic of Kazakhstan as a result of field research from 2017 ...Important taxonomic characters (Franke, 1992) included number and type of layers of the spore wall and their staining reaction to Melzer’s reagent; characteristics of inner walls, when present; morphology of the subtending hypha at point of attachment; and color and size range of spores.
