1a. Ascomata 0.4–1.5 mm diam, typically firmly embedded in pseudostromatic tissues intermixed with substrate cells, forming pallid areas around ascomata, often surrounded by blackened marginal zones and covered by a dark clypeus, ascospores hyaline when immature and becoming brown to dark brown..................................................................................................................... Massaria

1b. Ascomata 100–260 μm diam., not as above and ascospores always hyaline.....................................................................................2

2a. Peridium with a single stratum and comprising light brown cells of textura angularis, hamathecium of occasionally branched and septate pseudoparaphyses, ascospores 1-septate ............................................................................................................ Neomassaria
