Falciformispora

Falciformispora K.D. Hyde

Index Fungorum number: IF 25457; Facesoffungi number: FoF 08382

 

Saprobic on submerged wood, intertidal mangrove wood, dead wood or isolated from mycetoma of humans. Sexual morph: Ascomata solitary or gregarious, erumpent becoming superficial, subglobose or ovoid, glabrous, black, coriaceous, ostiolate. Peridium two-layered, outer layer composed of thick-walled angular or rounded brown cells, inner layer composed of elongate, hyaline cells. Pseudoparaphyses numerous, cellular, narrowly cylindrical, septate, anastomosing. Asci 8-spored, bitunicate, fissitunicate, clavate, pedicellate, with an ocular chamber. Ascospores bi- to tri-seriate, fusiform, hyaline, multiseptate, surrounded by a thin mucilage sheath with or without a single scythe-like appendage (Hyde 1992). Asexual morph: Undetermined. (Description from Dong et al. 2020)

 

Type species: Falciformispora lignatilis K.D. Hyde

 

Notes: Falciformispora was introduced to accommodate F. lignatilis collected from intertidal mangrove wood (Hyde 1992). Falciformispora is characterized by fusiform, hyaline, multiseptate ascospores surrounded by a mucilaginous sheath and appendage (Hyde 199). Falciformispora lignatilis was later collected from freshwater habitats in USA (Raja et al. 2009). It differs from another freshwater species F. aquatica D.F. Bao et al. in having smaller asci (110–136 × 20–32 µm vs. 115–167 × 28–47 µm) and ascospores (42–50 × 7.5–10 µm vs. 48–59 × 10–16 µm) (Hyde et al. 2019). Both F. aquatica and F. lignatilis have a single scythe-like appendage, while F. uttaraditense Boonmee et al. lacks this character (Hyde et al. 2020). Falciformispora uttaraditense was introduced based solely on ITS sequence data and morphology (Hyde et al. 2020). (Description from Dong et al. 2020)
