Type species:
Pedumispora rhizophorae K.D. Hyde & E.B.G. Jones, 1992. Mycol. Res., 96:
Sexual morph: saprobic, Pseudostroma: up to 130 µm thick, brown to black, covering the wood surface and enclosing elements of wood, with erumpent pustules containing 1-4 immersed ascomata, central region containing 1-4 short necks. Ascomata: 560-720 µm high, 660-1040 µm wide, brown to black, subglobose, coriaceous, ostiolate, papillate, sparse pseudostromatic tissues surrounding each ascoma. Necks: collectively erumpent and united, up to 320 µm wide, with periphyses. Peridium: 100-165 µm thick, an inner hyaline layer of elongate cells and an outer layer composed of melanized thick-walled hyphae forming a textura epidermioidea, incorporating host cells, the outside fusing with the host tissue. Paraphyses: 3-8 um thick, filiform and simple. Asci: 200-265 x 17-26 µm, 8-spored, irregularly fusiform, pedunculate, uni-tunicate, thin-walled, apically truncate without an apical apparatus. Ascospores: 160-240 x 5-7 µm, filiform, tapering towards both ends, curved with a characteristic hook-shape at one end, 13-17-septate, not constricted at the septa, with 7-9 longitudinal striations running the length of the spore, tips 15-30 x 1.5-2 µm, lacking cytoplasm, slightly inflated and yellow-yellowish brown. Asexual morph: Undetermined (Description based on Hyde & Jones (1992) and Borse et al. (2012)).
