Phylogenetic and morphological analyses on samples of Fistulina from East Asia and North America were carried out, and two new species were described, namely, Fistulina americana and Fistulina orientalis, both previously known as Fistulina hepatica. The former is characterized by lateral stipitate basidiocarps, relatively small pores (7-8 per mm), a monomitic hyphal system with both clamp ...

Melzer's reagent can be used to test whether spores are amyloid, nonamyloid, or dextrinoid . Spores that stain bluish-gray to bluish-black are amyloid. Spores that stain brown to reddish-brown are dextrinoid. This test is normally performed on white spored mushrooms. Melzer's reactions are typically almost immediate, though in some cases the reaction may take up to 20 minutes to develop. The function of the chemicals that make up Melzer's reagent are several. The chloral hydrate is a clearing agent, bleaching and improving the transparency of various dark-colored microscopic materials. The mounting medium used is Polyvinyl-Lactic Acid-Glycerol (PVLG) and PVLG mixed with Melzer's reagent. On a slide, gently place one drop of PVLG and another drop of PVLG+Melzer. Afterwards, place the spores using a Pasteur pipette with an extruded tip, taking care not to dispense too much water along with the spores. ...Melzer's reagent (lactic acid/water 1:1; Brundett et al. 1994).
