A lichen difficult to distinguish from Lecanactis abietina, L. subabietina and Opegrapha vermicellifera. Pd+ reaction would nail it. All 4 lichens scratch orange too #BLSlichens

This is an amazing find Sylvia! I should be so pleased if you could put your photo together with a couple of comments on its distribution and perhaps comparison with the sorediate one in a note to go in the next Bulletin. So many members miss all the fabulous stuff on social media #BLSlichens

Small black fruits of lichen on green thallus

A Little Black Dot lichen puzzled us during a survey of trees in a London park. Microscopic examination revealed it to be Amandinea punctata but the N enriched state of this site had resulted in a subsquamulose thallus with a thick algal layer unlike the typical thin pale crust. #BLSlichens

Beautiful community indeed. Are you in Canada? Looks like Teloschistes chrysophthalmus in your photo with a couple of Lecanoras and Ramalina species #BLSlichens

This a beautiful photo and the tiny crustose lichens are like jewels. I’m not familiar with lichens of America, living here in UK, but the orange one looks like an Acarospora or Myriospora #BLSlichens

A green powdery lichen on soil bank

A light green powdery lichen in a rock crevice in a bank

Here are 2 Lepraria species, one beside moss tolerating exposure to rain (cf Lepraria incana) and another at home in a rain sheltered crevice (cf L. humida).
Note L. incana a gives a white reaction with UV light #BLSlichens

Moss and a powdery lichen on stones on a bank beneath the root of a beech tree

Stones on a soil bank covered in pale green powdery lichen

Soil and siliceous stones among exposed beech tree roots provide the perfect habitat for frequently overlooked DUSTBIN LICHENS or Leprarias. Appearing as diffuse powdery granules they are tricky to identify needing TLC for certainty #BLSlichens
