Septofusispora
Septofusispora G.C. Ren and K.D. Hyde 2022
Index Fungorum number: IF 559804
Etymology: Epithet refers to the fusiform and septate spores of this genus.
Saprobic on decaying wood. Sexual morph: Ascomata solitary or gregarious, erumpent to immersed, globose-to-subglobose, black. Ostiole central. Peridium thick, comprising pale-to-brown cells of textura angularis. Hamathecium of septate, branched, cellular pseudoparaphyses. Asci 8-spored, bitunicate, fissitunicate, cylindrical-to-clavate, with or without an ocular chamber, with a pedicel. Ascospores overlapping, brown, fusiform, with 4–5 transverse septa, smooth-walled, guttulate. Asexual morph: undetermined.
Type species: Septofusispora thailandica G.C. Ren and K.D. Hyde.
Notes: In our phylogenetic analysis, Septofusispora is seemingly nested near Alloconiothyrium, Kalmusibambusa, Kalmusia, and Xenocamarosporium, but it is well-separated from these genera. Septofusispora has uni-loculate ascomata, clavate asci, fusiform, guttulate ascospores with 4–5 transverse septa, whereas the Kalmusia species have ovoid-to-clavate asci, ovoid-to-clavate, 3-septate ascospores (sometimes muriform), with a mucilaginous sheath. Kalmusibambusa has multi-loculate, elongate ascostromata, cylindrical asci, ellipsoidal-to-fusiform, 3-septate ascospores with round-to-acute ends and a wide mucilaginous sheath. Alloconiothyrium and Xenocamarosporium are known only from their asexual morphs. Most studies used molecular data to delimit species boundaries, which is not possible using morphological characters. Therefore, considering the morphological differences and phylogenetic support, we introduce Septofusispora as a new genus.
