Vaginatispora K.D. Hyde

Index Fungorum number: IF 27644, Facesoffungi number: FoF 00828


Saprobic on submerged wood, intertidal wood, dead twigs, endocarp or fallen fruit pericarp. Sexual morph: Ascomata solitary or scattered, immersed to erumpent, uni-loculate, subglobose, glabrous, dark brown to black. Ostiolar neck crest-like, elongate, laterally compressed, composed of globose to elongate, brown to black cells, with a pore-like opening and hyaline periphyses. Peridium unequal in thickness, two-layered, outer layer comprising somewhat flattened cells, fusing and indistinguishable from the host tissues, inner layer comprising lightly pigmented to hyaline cells. Pseudoparaphyses numerous, cellular, hypha-like, hyaline, septate, anastomosing above the asci. Asci 8-spored, bitunicate, fissitunicate, cylindrical to clavate, with a short or long pedicel, apically round with an ocular chamber. Ascospores uni- to bi-seriate, narrowly ellipsoidal or fusiform, straight to slightly curved, hyaline, 1-septate, occasionally producing pseudosepta, septum mostly median, upper cell slightly broader than lower cell, smooth, thin-walled, with bipolar appendages or entire sheath (Hyde 1995). Asexual morph: Undetermined.


Type species: Vaginatispora aquatica K.D. Hyde


Notes: Vaginatispora aquatica was collected from North Queensland, Australia (Hyde 1995). Zhang et al. (2014) transferred V. aquatica to Lophiostoma because it formed a basal clade to Lophiostoma species with high bootstrap support and morphologically resembles L. macrostomum (type species), in having immersed to erumpent ascomata with a slit-like ostiole, an unequally thick peridium, clavate asci, and hyaline ascospores (Hyde 1995; Zhang et al. 2014). With more sequences added in Lophiostomataceae, Vaginatispora (typified by V. aquatica) was accepted as a distinct genus in Lophiostomataceae (Thambugala et al. 2015). The freshwater collections of V. armatispora (K.D. Hyde et al.) Wanas. et al. were found from Thailand (Bao et al. 2019; Hyde et al. 2019).
