Massarina sp. P2921  

Anamorph: not known.
Teleomorph: Ascostromata 250-400 µm diam., ± globose, erumpent in linear or irregular clusters, surrounded by amorphous melanized material, with a papillate ostiole that hardly extends beyond the stromatic elements. Interascal tissue composed of of branched septate pseudoparaphyses ca 2 µm diam., tending to deliquesce at maturity. Asci 90-110 x 13-18 µm, narrowly clavate, thick-walled and fissitunicate, the stalk tapering and the apex obtuse to rounded with a poorly developed ocular chamber, 8-spored. Ascospores arranged biseriately, 26-30 x 6-8 µm, fusiform, eventually 3-septate, the primary septum strongly constricted and the secondary septa less so, the cell above the primary septum slightly broader than that immediately below, hyaline, smooth, fairly thin-walled, surrounded by a broad gelatinous sheath.
