Savoryella E.B.G. Jones & R.A. Eaton, Trans. Br. mycol. Soc. 52(1): 161 (1969)

Savoryellomycetidae, Savoryellales, Savoryellaceae, Savoryella

Index Fungorum number: IF 4870; Facesoffungi number: FoF 02131; 13 morphological species (Species Fungorum 2020); 9 species with sequence data.

 

Saprobic on submerged wood in rivers, streams, cooling towers and marine environments. Sexual morph: Ascomata perithecioid, globose, subglobose or ellipsoidal, immersed, partly immersed or superficial, membranous, pale and dark brown, long necked, ostiolate, papillate. Ostiole periphysate. Peridium brown, composed of numerous layers of thick-walled angular cells forming textura angularis. Paraphyses present, few. Asci 2–8-spored, cylindrical or clavate, short-pedicellate, unitunicate, persistent, with a truncate, non-amyloid apical thickening containing a pore. Ascospores uni- or biseriate, ellipsoidal, 3-septate, not noticeably constricted at the septa, central cells brown, apical cells smaller and hyaline. Asexual morph: Undetermined (adapted from Maharachchikumbura et al. 2016).

Notes: Savoryella (Jones & Eaton 1969) currently comprises eleven species (Hernandez-Restrepo et al. 2017, Dayarathne et al. 2019). Savoryella limnetica was combined under Ascotaiwania limnetica, re-described with a new asexual morph by Réblová et al. (2015) and synonymized under Neoascotaiwania limnetica by Hernandez-Restrepo et al. (2017). However, Dayarathne et al. (2019) synonymized Neoascotaiwania under Ascotaiwania. Savoryella has been placed in several orders; Sphaeriales family incertae sedis by Kohlmeyer & Kohlmeyer (1979), ascomycetes incertae sedis by Kohlmeyer (1986), Amphisphaeriaceae (Eriksson & Hawksworth 1986) and Sordariales (Jones & Hyde 1992). Barr (1990) transferred this genus to Halosphaeriales (now Microascales) based on morphology (the catenophyses-like paraphyses) and ultrastructural observations. Vijaykrishna et al. (2006) and Cai et al. (2006) referred Savoryella elongata and S. longispora to Hypocreales, subclass Hypocreomycetidae, based on a phylogenetic analysis of LSU data, although with weak statistical support. Jones et al. (2009) referred the genus to the Sordariales genera incertae sedis based on morphology. Boonyuen et al. (2011) introduced the new order Savoryellales to accommodate the genera Ascotaiwania, Ascothailandia (and its asexual morph, Canalisporium) and Savoryella based on multi-gene dataset. Dayarathne et al. (2019) showed that divergence of this genus was 108 (72–146) MYA.
