I came across this intriguing collection of funghi in Law Park in Briarcliff Manor. I’m not entirely sure what they are (mushrooms tend to look alike to me), but my research leads me to believe that they’re young smooth common inkcaps. If so they have the interesting characteristic of being toxic only when consumed with alcohol. See The Mushroom That’s Only Poisonous If You’re Also Drinking. I know that these mushrooms don’t look much like those in the article, but that’s apparently the way they look as they get older. When they get really old they start to break down and become liquid – and this liquid has been used as ink, hence the name.
