After checking over 40 species of Phaeosphaeria I started to run out of ideas when I came across P. inclusa thanks to Alain Gardiennet record of 27/02/2016. Although on a different substrate this was the only ascospore I could find with the fourth cell swollen and with eight overall cells/7-septate with the next 3 cells 'squeezed' together with the last largely pointed. Consistent in all spores. P. herpotrichoides came close but would only show the third cell swollen. 

Details inc: Substrate: Bromopsis type grass, perhaps B. benekenii.
Pseudothecia black slightly embedded with black ostioles <0.5mm longitudual growth.
Asci: 75 - 95 x 9.73 - 10.75µm, IKI -, seriate
Ascospores: 21.55 - 29.44 x 4.08 - 5.18µm. 8-celled, 7-septate with the fourth cell swollen, following three cells tight with the last cell pointy.
Paraphyses: Slender, multi-septate, rounded tips, tips remaining hyaline in Iodine.

Would apprecaite any guidance. Thanks.
