Has anybody any idea what this is(see photos).Plant is a small conifer that has been growing in a pot for a number of years and until two weeks ago, was ok. Then this `growth` appeared, but only in wet weather. When weather is dry there`s nothing there. Yesterday (Sunday)--nothing, today (Monday-with rain overnight)covered with this horrible jelly like substance, which when it gets too heavy falls on ground. Until I know what it is I`m not sure what to do about it.
Any help appreciated.

Its one of the gymnangosporium rusts, a fungal infection - these protrusions mean its 'hatching out' and now will be seeking either a pear or apple tree in order to complete its life cycle. People usually worry more about their apples and pears than they do the conifer (usually juniper) that's hosting the first part of the fungal life cycle - there is no treatment. At an earlier stage, before these 'horns' appear, you can cut out any growths you see, but if you've an apple or pear tree, I'd get rid of this plant.

Wow Bamboo, how interesting! Only of course if it's not in your own garden! All a bit like an alien invasion, never seen this before which just goes to prove we all learn something new every day - fascinating.
Sorry about your tree though Richard.

Sadly, these infections are becoming much more widespread, so you'll probably encounter it at some point, Honeysuckle, maybe in a park or a neighbour's garden.
