A 3–10% solution of potassium hydroxide (KOH) gives a color change in some species of mushrooms: In Agaricus, some species such as A. xanthodermus turn yellow with KOH, many have no reaction, and A. subrutilescens turns green. Distinctive change occurs for some species of Cortinarius and Boletes
A printable chart to make a spore print and start identification. The spore print is the powdery deposit obtained by allowing spores of a fungal fruit body to fall onto a surface underneath. It is an important diagnostic character in most handbooks for identifying mushrooms. It shows the colour of the mushroom spores if viewed en masse. [1]
A 2008 molecular phylogenetic study clarified the relationships among the mushroom-forming species of the family. [15] The authors demonstrated the existence of four distinct lineages of gilled mushrooms, which led to the description of Multifurca as a new genus separated from Russula [15] and the segregation of Lactifluus from Lactarius. [16] [17]
Despite the difficulty in positively identifying collected specimens, the possibility to spot the toxic species by their acrid taste makes some of the mild species, such as R. cyanoxantha and R. vesca, popular edible mushrooms. Russula is mostly free of deadly poisonous species, and mild-tasting ones are all edible. [14] [failed verification]
The poisonous jack-o'-lantern mushrooms (genus Omphalotus) comprise another group of lookalikes; however, they have straight, non-forked true gills. [45] The European wood-rotting species Haasiella splendidissima , [ nb 1 ] sometimes confused with H. aurantiaca , is most readily distinguished from the latter by its pink spore print and gills ...
Identifying death caps and what to do with them One of the most noticeable features of any mushroom in the Amanita genus is the universal veil, a membranous tissue from which the fungi emerge.
No matter how experienced you are, if you aren’t 100% sure of a mushroom’s identification, don’t eat it. Morel mushrooms have returned to WA. What to know, how to avoid ‘poisonous’ lookalike
Xerocomellus zelleri is an edible species, [15] although care should be taken to ensure that specimens collected for consumption are free of fly larvae. [16] In his book 100 Edible Mushrooms , Michael Kuo gave the mushroom an edibility rating of "mediocre". [ 17 ]
