Tiny Tuesday....Lichen

I woke at 5.15am this morning and just could not get back to sleep, so up at 6.30am, and an hour and a half of dance/excercise class at 10am.... I will never last the day out !!  I found some lichen on a branch of a tree for tiny Tuesday ....this week no theme. I also discovered that if I use a higher F number, I can get more of my subject in focus....Thanks to Osuzanna for hosting :)

Thanks so much for the lovely responses to yesterday's mono.
Poppy seeds are in the post !!
