brought in at a foray. Although tiny, they are fairly
conspicuous when you know what they look like.

wood brought in during a foray. Interestingly, the tips of
fruit bodies are all bending in the same direction - suggesting
a response to light (i.e., phototropism)
(i..e, gravitropism). Photo © Gary Emberger.

the browning of the tips is due to dehydration. Photo © Gary
