Sat 27 Feb: Community Groups Showcase Open Day at St John's Church, Settle, BD24 (JH

Welcome to our Community Groups Showcase Open Day at St John's Church Hall Settle 
on Sat 27 February: 10am-4pm: Bacon butties, coffee, 12 groups performing or giving demonstrations; Children's activities (Messy Church) - and a variety of stalls..
Here is the programme -  I hope you can call in during the day
I will be selling the Rainforest Cards.
It would be nice to sell 100 cards and thus save 1 acre of Rainforest!
But I won't get too excited.. I suspect I will be too busy visiting other stalls, and helping other groups.. and Scottish dancing at 12.30. to be at the Rainforest Fund card stall all day.
On Sunday there is a special service to celebrate the completion of our new Worship Room / church.
If you live near Settle DO come!!!

Physcia tenella - Fringed Rosette Lichen

 Learn your lichens 7.
The Physcia is the teeny weeny grey foliose lichen covering the trunk in the bottom two thirds of the picture on the left. (The large grey foliose lichen is a Parmelia (saxatile or sulcata) - I'll write about that another day)

You are probably more likely to find Physcia on a tree in Settle than any other species of lichen.  If you can see a big yellow Xanthoria have a look nearby for Physcia.  Tenella means delicate.

Learn your Lichens Series
1. Arthonia radiata
6. Lecanora gangaleoides
7. Physcia tenella

The ruler on the left shows centimetres
divided into millimetres. Look more closely..

This one is fruiting. You can see the black discs. 

This species of Physcia has cilia ("hair-like projections"), sometimes with black tips growing from the undersurface.
I photographed this through my hand-lens. See the cilia
The thallus has gone pinkish because it is infected by a fungus

The top picture is of Physcia tenella on this Mountain Ash at Langcliffe, but there are at least 12 other species of (mostly bigger) lichens on it too - a fantastic tree.
....and five mosses
.... and two liverworts.
I photographed the other pictures on the nearest tree here in Malham YDNP car park several years ago, ready for my Algae and Lichens of Malhamdale walk.

The tips of the thallus are curled up at the top right of the picture and the under-surface of the tips are covered with powdery soredia. You can see the cilia clearly here.  this picture was taken on an oak branch in Grinton churchyard
