So you can imagine how excited I was University of New York and The New when Kerry invited me out to California to York Botanical Garden in New York City. explore the mountain ranges of southern In 2008 I received a student grant from California with him for a week.

There we talked over gin and mind full of field observations. We tonics well into the evening. The next day we made our way to the heights of the San Jacinto Mountains where we visited an unusual ravine along the North Fork of the San Jacinto River. This ravine was narrow and deep, cool and shaded, and perhaps most importantly it was moist. Every surface was carpeted with Lepraria. I had seen some of these lichens back east, however the ones at North Fork were entirely different. In my zeal I made many collections, especially of a species with a thick felty thallus. Only later would I learn that this had been my first encounter with Lepraria rigidula, a rare species in Figure 1.
