Depending on weather, you may see a range of fungi or none at all. You might see cherry blight. In some years we find coral fungi, puffballs, and mushrooms of various sorts. Obviously planting junipers near apple trees is not adviseable as they are the alternate hosts for this fungus. Here you see this kind of planting at the edge of the arboretum.
Mosses abound on creek banks, wetland soils, and tree-trunk bases.
Some will show the green gametophytes only, but some will have last year's and this year's sporophytes attached. Polytrichum lives in drier upland sites. Other species, such as Mnium are more likely found on wet sites. Liverwort colonies occur on the banks of the creek, but are relatively rare. I have collected Conocephalum and Pallavicinnia there.
