Funga Nordica?

Darvin – this is strange, you don’t know about Funga Nordica? I think I’ve been siting it for many if not most of my European obs. over the past two years.

Looking over that link there Irene I see a book on Lactarius I didn’t know about, I’d like to be able to see a copy of that one.

Also if the difference is really on the color of bright orange to pale beige, what am I to make of this photo:

Which is all samples from the same patch of moss up in Mendocino.

was published a 2008, as a new “Nordic Macromycetes”, with big improvements (no species “not included in the key”, and much better descriptions), but also much heavier (2.2 kilo) – available on CD too.
Editors are Knudsen & Vesterholt. The danes are selling it here:

Here’s an example :-)

Cap 3-15(-20) mm, convex, low convex with papilla to umbilicate, with straight, undulating or crisped margin, hygrophanous, translucently striate halfway to centre, dry, dull, minutely pubescent (lens), centre deeply coloured, paler towards margin and between the striae; gills arcuate-decurrent, distant, sometimes forked, slightly intervenose, with minutely pubescent edge, white to pale orange; stem 10-50 × 0.5-1.5(-2) mm, cylindrical, hollow, dry, dull to shiny, minutely pubescent over entire length, base white strigose, orange, pale yellow to hyaline white; flesh thin coloured like surface. Sp (4-)5.5-7(-7.5) x 2-3(-4) μm, long ellipsoid to cylindrical, smooth (fig. 67J), thin-walled; cheilo- and pleurocystidia 30-60 x (4-)6-9(-13) μm, fusiform to narrowly lageniform, often subcapitate, thin-walled, smooth, hyaline; pileocystidia 40-80 × 10-15 μm, similar to cheilocystidia.; caulocystidia 30-100 × 8-15 μm, similar to cheilocystidia, but often slightly thick-walled. Single or in groups in moist moss, in forests, open grassland, heathland and on lake shores; spring to autumn; very common in temp.-arc./alp., occasional in IS; DK (LC), FI (LC), FO, IS, NO (LC, incl.

R. mellea (Singer & Clémençon) Lamoure

Antonín and Noordeloos have an excellent description if R. mellea, Nortic Macromycetes mentions it, only to say it’s not mentioned (not dealt with) and Flora Agaricina Neerlandica skips it.
What is Funga Nordica? Got an author or pub date to follow a lead?

Antonín, Vladimír and Machiel E. Noordeloos. 2004. A Monograph Of The Genera Hemimycena, Delicatula, Fayodia, Gamundia, Myxomphalia, Resinomycena, Rickenella, and Xeromphalina (Tribus Mycenae sensu Singer, Mycena excluded) In Europe. IHW Verlag, Eching. 279p.

Not much

- mainly the beige colour and the smaller size of mellea (I just realized that what I have called mellea earlier here is something else).
Macro- and microcharacters are described in Funga Nordica.

what distinguishes the two species, Irene?
