I used a concoction of my own it works most of the time but not all the time, thanks for your help, how can I make or get Melzers?

jrussula, be true to your name and learn that the spores of
Russulales are amyloid. You must be doing something wrong. I
think we need to review all your steps and help you. You mention
iodine, but is that Melzer’s or just plain iodine, or something

Differs from L. affinis
1. L.sp is almost always larger
Cap of L.affinis is 8-10 cm wide
Cap of L.sp… 9-16 cm wide and often more

Stalk of L.sp…6-10cm long 1/12 – 3 cm thick and some times more
Stalk of L. affinis is 2.5 – 8 cm tall and only 1.4 – 2.4 cm thick( Roger Phillips)

4. spore print of L.sp cream..
L. affinis spore print white (Roger Phillips)
L. affinis spoe print cream to pinkish (Helene M.E. -Barendsen)

5. Taste of L. sp MILD
Taste of L. affinis ACRID (David Arora) (Roger Phillips)
(Helene M.E. S-Barendsen said taste mild then acrid…..

6. Habitat Of L.sp North west North America
Habitat of L. affinis…found in North Eastern North America (Canada)…(Roger Phillips also said found in The east)
(David Arora said it is rare or absent in west)
Helene. M.E.S-barendsen found it in Alberta Canada…(wolf Lake)….

I used David Aroras book Mushrooms Dymistified..
Roger Phillips book Mushrooms and other fungi of North America,
Helene M.E. S-Barendsen’s book Mushrooms of Western Canada,

said not to be uncommon in North America and simillar to L. pallidus of Europe.
