Leptosphaeria puzzle

I have collected a Leptosphaeria on the dead stem-bases of last year's Tanacetum vulgare.The spores are almost all 3-septate, with a few developing a fourth, and a very few developing a fifth septum. Spore measurements are 19.1-23.9 x 5-5.7µm, in other words perfect for L. doliolum; however try as I might I cannot see evidence of the concentric ridge(s) on the pseudothecia which I would expect on that species, whether they are occuring below the stem cortex or on the bare stems. Photo's below: any suggestions welcome.Chris
