Stropharia pseudocyanea?

Description:

Growing on a grassy bank, about 2.5cm across and 7cm tall. Two fruitbdoes found. At the moment I think there's three species that are similar (and closely related) in the UK; S. aeruginosa (1879 records), S. caerulea (954 records), and S. pseudocyanea (579 records) all listed as separate species on fieldmycolgy.net. first-nature.com describes S. aeruginosa as being different from S. caerulea; 'Stropharia aeruginosa is darker blue-green and its cap scales are persistent; it has reddish-brown gills with white edges.' I get the impression from a post by Chris Yeates of wildaboutbritain that you need to use microscopy to determine whether this is Stropharia caerulea or a look-a-like: http://www.wildaboutbritain.co.uk/forums... According to Wikipedia, compared to S. aeruginosa, Stropharia pseudocyanea is 'smaller; slighter, but strikingly similar grassland species, with a very fleeting ring.'. Stropharia caerulea is 'a dowdier cousin.' (http://en.wikipedia.org/wiki/Stropharia_...). Just based on the size and lack of persistent scales I'll guess S. psuedocyanea but to ID with any certainty I'd have to look at it under a microscope
