I have a faulty phone-line just now, so like Leif I am currently 'Internet-challanged'. Doing my best here with the fungus posts.
Still, these are very nice photographs from an area where I have been looking at fungi in the basalt pastures myself, whenever I get the chance.
1: Galerina pumila
It is much the commonest acid grassland Galerina with white flecks of veil on the stem, as shown so well in your photograph. Colour often a fairly bright orange-brown.
Other common Galerina species in the same habitat are:
G. mniophila, much duller colours, very pale stem without conspicuous veil remains, larger spores. Likes wetter weather and often in patches of Polytrichum formosum (a moss).
G. vittiformis, variable, but often with stem darker below, stem minutely pubescent with projecting cystidia, except when students have been handling it!
2: Lycoperdon foetidum
Often common in acid pastures.
3. Hygrophoropsis aurantiaca
As Leif says, it is a bit odd for that species, but it is variable in colour and I often see young specimens with immature gills. The cap is indeed fluffy at that stage. It seems to vary more in grasslands than in woodland.
