Possible Anthracnose?

(",)

I have several plants in my garden that are afflicted with something that I suspect might be anthracnose (it is a problem here in WA, though I had no idea it could affect sucha a variety of plants).
My Malabar Spinach (see photos), Lablab beans (photos) and now my peas (photo) all have suspicious spots and things that I can't identify. The Malabar is greatly affected - not sure I can save the plant. The Lablab beans are too, but they might pull through. The peas have only just developed these spots.

These plants are not close to each other in the garden - the beans are a good seven meters away from the peas (which are in a pot), and there is a wall of old-growth ivy and a patio (inc. furniture) between them. The Malabar Spinch is again that far from the peas, with a various plants (inc. a sugar palm) in between. (The beans and spinach are nigh on opposite sides of the large garden). There is traffic between the areas, which could explain the spread, I guess; though I do wonder why nothing elsein between  seems affected. I seem to have rust fungi around as well... seems to be pretty common.

We've had a rainy winter so far, quite cold for where Perth (quite a few nights of 5-7 degrees with 15 degree days) but there are always a few days that heat up to 19 or so degrees, which seems to be what a lot of fungal spores want: damp and warm-ish.

Any help is much appreciated!
