#lichenGBI Caloplaca teicholyta with apothecia. First time I’ve seen it fertile. On calcareous ironstone, Warwickshire, UK. Used video to catch the red reaction on the apothecial section, as it dissolved out rapidly. The soredia gave a faint pinkish reaction to K (not really ‘dull violet’) >

White lobes, and white/brownish soredia away from the edgeSection of apothecium in KOH. The upper layer of the apothecium (dull reddish in water) turned bright red in KOH, but rapidly dissolved and dispersed. More or less continuous green algal layer below the hymenium.

Labour blocks proposal for ‘swift bricks’ in all new homes
MPs had previously backed Conservative amendment to ask developers to provide hollow bricks for endangered birds Providing every new home with at least one “swift brick” to help endangered cavity-nesting birds has been rejected by Labour at the committee stage of its increasingly controversial planning bill. The amendment to the bill to ask every developer to provide a £35 hollow brick for swifts, house martins, sparrows and starlings, which was tabled by Labour MP Barry Gardiner, has been rejected by the Labour-dominated committee.

So Labour say they won't install swift bricks because they are moving away from specific species mitigations to landscape level ones. But swifts nest IN BUILDINGS. So how is landscape-level compensation supposed to help? Just ecologically illiterate nonsense 🤦‍♀️ www.theguardian.com/environment/...

Photo of two cream coloured lichens, one behind the other. Both look like they have faces (due to the position of apothecia). The lichen in front looks like it’s just been frightened. Based on its “facial expression”, the one behind looks like it’s just said something to the lichen in front.
