I saw more yellow fungi in the grass

I posted earlier about the White Spindles growing in clumps. if you'd like to find out more about these then Michael Kuo is my favoured expert.  He's described them as 'little clumps of wiggling white worms'. 

Ask someone to describe what they think of when you mention fungi and the chances are they will come up with something with a cap and stem. Fungi are incredibly varied though and for me that is why they are endlessly fascinating. Spindles, clubs and coral fungi often get lumped together but as Michael Kuo points out there are many different species but share common visual features.

 Left is probably Clavulinopsis laeticolor  and 'is, as a translation of its Latin name suggests, joyfully colored; it is typically orange or orangish yellow'
Kuo, M. (2003, December). Clavulinopsis laeticolor. Retrieved from the MushroomExpert.Com Web site: http://www.mushroomexpert.com/clavulinopsis_laeticolor.html

Below could be Clavulinopsis corniculata because of the branching stems. But it's difficult to be sure and this group looks a little small. Reading up on these, microscopic scrutiny is often needed to verify them as well as the application of iron salts to see the colour change.
