Dried specimens were used for microscopic observations, using 5% KOH as the floating agent, Melzer's reagent was used to examine the presence of amyloid or dextrinoid reactions. Slices of lamellae and pileipellis were observed under the Olympus BX 53 microscope. Free hand drawings were made from all microscopic observations.Melzer's reagent examined with a compound microscope. Their shape, size, colour and bulbous suspensor, sporocarp, surface ornamentation, vesicles etc were recorded. Spores were classified into each spore type based upon morphology.

Václav Melzer. Václav Melzer (26 August 1878 - 1 May 1968) was a Czech teacher and mycologist, who was part of a group of Czech teachers who became mycologists at the beginning of the 20th century that also included figures such as Jindřich Kučera, Rudolf Veselý, and František Tyttl.
