Lecania coeruleorubella 2.jpg
NOT Lecania coeruleorubella! This image was original posted as L. coeruleorubella but a re-examination of the specimen showed that the large convex apothecia belong to Bilimbia sabuletorum, and these are growing through the blastidiate thallus of sterile Lecania erysibe. The lower half of the image is occupied by Lecania inundata (nodular thallus of L. inundata not well illustrated by this image). This material of B. sabuletorum has, unusually, a pale hypothecium, and mainly 3-septate ascospores.
