Fungalpedia – Note 1949, Pseudoornatispora

 

Pseudoornatispora Tibpromma & K.D. Hyde

Citation when using this data: Hyde KD et al. 2020 – Fungalpedia, Ascomycota.

Index Fungorum, Facesoffungi, MycoBank, GenBank, Fig 1

Classification: Stachybotryaceae, Hypocreales, Hypocreomycetidae, Sordariomycetes, Pezizomycotina, Ascomycota, Fungi

The genus is characterised by black ascomata with seta and ostioles, 6–8-spored, unitunicate asci, hyaline, 1-septate, verrucose, fusiform ascospores, mononematous conidiophores, phialidic, hyaline conidiogenous cells, ellipsoid, hyaline to subhyaline, aseptate, guttulate conidia, without a mucilaginous sheath (Tibpromma et al. 2018). This genus is similar to Koorchaloma and the species of these two genera grouped together in the phylogenetic analysis generated from combined ITS, LSU and rpb2 sequence data (Li et al. unpublished data). We maintain these two genera as distinct. Pseudoornatispora krabiense is illustrated in this entry.

Type species: Pseudoornatispora krabiense Tibpromma & K.D. Hyde.

Other accepted species: Species Fungorum – search Pseudoornatispora.
