Spores

Ok, I just checked out the spores and got a range of (7.5)8-9.5 x (5.5)6-6.5

I forgot to mention the KOH reactions were blood red on pileus and stipe but a purple/lilac colour on the lamellae and top of the stipe.

Well..

..I think your collection is very similar to Horak’s image at the landcare site, the only distinct difference is in the pigment of the pileus, this may just be a variation in colour or it may be a very closely related species, could you say anything about the average length and width of the spores and the ornamentation?

Thin-layer chromatography may be necessary to check if there are any different anthraquinonic pigments present.

The specimens in my observation of this species agree in all macroscopic and microscopic characteristics with Horak’s description, it is very similar to your collection but the cap is distinctly dark brown.

The notes in Horak’s description mention that the Western Australian material and the Victorian material agree in all morphological characteristics and pigment patterns with the New Zealand material so it is possible that your collection may represent a separate taxon, I look forward to hearing about the spores!

Thanks for the comment. The pileus was a little darker in older specimens and almost black in the centre over the umbo, but they don’t look anything like the pics on NZ landcare website. Are the Australian collections are a colour variant (or an entirely different species)? These are the colours seen in Australian field guides and are almost identical to those pictured in Fuhrer’s book. The bright red gills were amazing and so intense, especially in the younger mushrooms.

Looks good…

…although the pileus in your collection is quite red, the description mentions a black to dark brown pileus centre with a yellow-orange margin in mature specimens, the stipe in your collection is a good match, golden yellow with very dark almost black veil remnants.
Good collection!
