It looks like Ascobolus michaudii

Thank you, Jacky.  I am having some difficulty understanding the finer points differentiating A. lignatilis, foliicola, furfuraceus, michaudii.  In another post on the topic on this forum François Valade comments that the brown walled excipulum cells (in michaudii & lignatilis) vs. hyaline or yellow cells (in foliicola)--but I'm not sure I'm translating these concepts properly. At any rate I have made more images, including more mature apothecia, mature spores and excipulum.  Spores at maturity seem to be quite reliably 16-18 x 9µm, brown, with some branching grooves--even some that connect laterally. Q=1.93  The apothecia only reach 3-4 mm in diameter.  Perhaps there is more detail here that could confirm A. michaud?
