Abstract

Sulcispora is typified by S.pleurospora. We collected a sulcispora-like taxon on leaves of Anthoxanthumodoratum L. in Italy and obtained single ascospore isolates. Combined ITS, LSU, SSU and tef1 sequence analyses suggested that Sulcispora is placed in the family Phaeosphaeriaceae and a newly collected Sulcispora species is introduced here as S.supratumida sp. nov. Detailed descriptions and illustrations are provided for Sulcisporasupratumida and it is compared with the type species, S.pleurospora.

Highlights

Phaeosphaeriaceae is a highly diverse and large family in the order Pleosporales (Hyde et al 2013) with more than 42 accepted genera (Hyde et al 2017; Karunarathna et al 2017; Wanasinghe et al 2018)
All individual trees generated under different criteria and from single gene datasets were essentially similar in topology and not significantly different from the tree generated from the concatenated dataset
The internal transcribed spacer nrDNA (ITS) sequence of the CBS 460.84 is almost identical to our strain (MFLUCC 14–0995)

Summary

Introduction

Phaeosphaeriaceae is a highly diverse and large family in the order Pleosporales (Hyde et al 2013) with more than 42 accepted genera (Hyde et al 2017; Karunarathna et al 2017; Wanasinghe et al 2018). Sulcispora was proposed by Shoemaker and Babcock (1989) as a monotypic genus to accommodate Sulcispora pleurospora (≡ Phaeosphaeria pleurospora Niessl). Some morphological characters of Phaeosphaeria pleurospora did not fit within species concepts of Phaeosphaeria and Shoemaker and Babcock (1989), introduced the genus Sulcispora. The genus name refers to the numerous furrows on the ascospore wall (Shoemaker and Babcock 1989). Sulcispora pleurospora has been reported on monocotyledonous hosts in genera such as Anthoxanthum, Carex, Deschampsia, Sesleria and Tofieldia (Leuchtmann 1984; Shoemaker and Babcock 1989)
