what type of surface do you take spore prints with

 

paper or glass ?

 

 

 

 

Thanks D

what type of surface do you take spore prints with ... paper or glass ?

 

David,

Depending on the colour of the sporee, I use white or black paper (see : Sporees), but I prefer using plastic from blisters (over glass), because one can cut the plastic in the shape needed to cover a water filled glass or jar and easily make a hole in the center to put the stem through, so its base touches the surface of the water in the jar. And afterwards, the sporee can be sealed with adhesive tape and fitted with the colour of background needed.

Which literature do you have, to compare spore colour to ?

 

Can you recommend any ?

Methuen Handbook of Colour, Munsell Soil Colour Book and genus specific books on Russula and Lactarius, such as F. Kränzlin (2005). Pilze der Schweiz, Part 6 (page 15), which uses the Y-M-C coding of the EURO-scala of printers.

Thanks Gerrit,

 

do you know of the Crawshay (1930) A-H colour code?

I understand Roger Phillips uses this for the Russula & Lactarius sp.

 

It seems to suggest that the R & L sp only have spore colour ranging from pale cream through to yellow ochre ?

 

Not familiar with any other colour range for those myself, but I'm suprised there's no dark colours listed

 

Can you shed any light ?

1. do you know of the Crawshay (1930) A-H colour code?

1. No, and I don't know anyone else (besides Roger Phillips ?) using it.

2. Why for ... sake ? There goes international standardization of sporee colour down the drain. As I can't compare the colour range used by Phillips with the range used by Kränzlin, I only can summarize the total range of the 24 colours he uses, which is 0 Y (white) through 40 Y, 18 M, 3 C (yellowish cream) to 80 Y, 40 M (dark ochre), with Y being yellow, M magenta or red and C cyan or blue, and that's as dark as it gets with Russula and Lactarius.

I had a feeling there would be more, thanks for the info Gerrit

White spore of Fomes fomentarius & Brown spore of Ganoderma resinaceum, here on Turkey Oak

Interesting e-mail I just received

 

A masters student from Manchester University has asked me if I know where/how he could get some spore from Ganoderma australe

 

He's doing a disertation whilst studying Chemical Engineering.

 

Project is about how Ganoderma breaks down wood etc......

 

Haven't personally got any spare spore hanging about just at the minute, but wondering if any north west arbs would be interested in obliging his request with a location for a bracket in situ?

 

I've advised him on the pitfalls of misidentification of the macro features of messrs applanatum & australe steering him in the direction of the herbariums at Kew/Edinburgh to aid in any microscopic ident issues.

 

Let me know if anyone can help

David, let me dig some images out...
