Table 2. Main diagnostic characters of Mediterranean Microporella species. Abbreviations are as follows.; Colony form: E, encrusting; EC, erect cylindrical; EB, erect bilaminar. Ascopore: C, C-shaped; O, circular lacking distal denticle; R, reticulate. Ovicell: NP, non-personate; Pe, personate, ascopore not included; PA, personate, ascopore included; RI, visor-like proximal rim; ov, peristome arching on the ascopore. Pseudopores: ev perf, evenly perforate; centr, centrally; margin, marginally. Others: P, present; n.o., not observed; NO, not occurring. Numbers in brackets indicate formulas that are observed less commonly.
