Type species – Rasutoria abietis (Dearn.) M.E. Barr, Mycotaxon 29: 502 (1987).
≡ Dimerosporium abietis Dearn., Mycologia 18(5): 243 (1926).
Notes – Rasutoria was introduced by Barr (1987a) for Dimerosporium abietis, and is characterized by its occurrence on conifer needles, setose ascomata, superficial on a radiating mycelium that penetrates the plant stomata (Winton et al. 2007). Sequence data of two Rasutoria species were provided by Winton et al. (2007). However, their phylogenetic placement as a distinct family (Euantennariaceae) in Capnodiales is not well-resolved (Winton et al. 2007, Hyde et al. 2013, Chomnunti et al. 2014). Two sequences of Rasutoria have a close relationship with species of Mycosphaerella and Phaeocryptopus, Mycosphaerellaceae (Winton et al. 2007, Hyde et al. 2013, Chomnunti et al. 2014). Videira et al. (2017) synonymized these two species with sequence data under Zasmidium based on phylogenetic analyses. Morphologically, Rasutoria shares some characters with Mycosphaerella and Phaeocryptopus in its globose, thin-walled pseudothecia, without pseudoparaphyses, bitunicate, ovoid to cylindrical, 8-spored asci, and fusoid to obovate, equatorially euseptate, hyaline to pale brown ascospores (Winton et al. 2007). However, Chomnunti et al. (2014) and Wijayawardene et al. (2017a, 2018) retained this genus within Euantennariaceae based on its sooty mould lifestyle.
