| | | Unknown mycena/hemimycena
The minute fruitbodies pictured (1.5mm) were buried under and on Betula leaves. The all had the strange gelatinous "lump" on top of the cap. I was unable to determine whether they had a separable pellicle but in fact the whole cap seemed gelatinous. They had only rudimentary lamella. The base of the stipe was slightly bulbous.
Any thoughts

Lots of thoughts Mal, but none of them useful in diagnosing this - I wouldn't even like to hazard a guess about this one !

You have frightened everyone else off Nick. Come on Ken you have the book on Hemimycena  . Whats the difference between Mycena and Hemimycena and what microscopic details should I be looking for to point me in the right direction?

Mycenas don't often make it onto my shortlist of species for microscopic work, let alone even smaller white jobs. Maybe next lifetime... or retirement, perhaps.
On Hemimycena, Antonin and Noordeloos say: "the genus Hemimycena as presented here may well be a rather artificial assemblage of species, sharing the common character of being small to minute, white or whitish, resembling a small Mycena, Omphalia, or Collybia, with thin-walled, inamyloid spores, and often well differentiated covering layers of pileus and stipe, and hymenial cystidia."
Not sure that helps really. 
Accurate identification of these species is obviously a complex and time-consuming business and I don't think I could give you much more of a pointer without reproducing the keys and much of the text in the book.
