This looks more like Sarcogyne to me

My impression is that Lecidea laboriosa has fairly regular apothecia, while Sarcogyne similis (and relatives) have contorted rims like these. If you ever see apothecia “vegetatively dividing”, then you know for sure you have Sarcogyne. (The other related genus worth mentioning is Polysporina, also with many spores per ascus, and convoluted to gyrose apothecial disk.) Another convenient method that can help distinguish the endolithic Lecidea from Sarcogyne is the color of the apothecia when they are wet. Lecidea has dark black-green or black-brown epihymenium that appears black to the naked eye even when wet. Sarcogyne has varying shades of brown epihymenium which can appear richly reddish, for example, when wet.
