Smardaea, reticulate ellipsoid spores

last week I finally found a Smardaea but it doesn't seem to be one of the usual species.
It grew on a place, where cut trees are temporarily stored, now unused for some time and overgrowing with plants. Spruce plantation, 285 m a.s.l., northern Moravia (Czech Rep.).
Apothecia up to 6 x 4 mm, dark violet.
Purplish pigment in all parts (ectal excipulum, subhymenium, some asci, spores a bit purplish too), with lactic acid it discolors to wine red and coagulates to small brown crystals.
Ascus base pleurorhynchous. Paraphyses clavate to slightly capitate, usually hyaline.
Spores (broadly) ellipsoid, *(16,8) 17,3-18,8 (19,1) × (11,6) 11,9-12,6 (13) um (alive, freshly ejected), or 16,3-18,2 × 10,3-11,9 um (dead in LACB and still in asci), with 2 big guttules and sometimes a few small ones.
Part of the spores in ascus is often abortive, only sometimes all of them mature (and then they are a bit narrower).
Ornamentation: uneven reticulation, about 0,6 um high (visible on the outline), in LACB the perispore swells and loosens a bit.
The closest description I found in Benkert (2005) as "S. obtusispora ad int." (the Chemnitz collection). The spore size, ornamentation, and frequently less than 8 spores in ascus fit his description, but in this collection the spores have more pointed ends. I didn't read anything about loosening perispore in Smardaea, only Donadini notes very sensitive ornamentation in S. reticulosperma that can be damaged by pressing to much on the coverslip.
Can this be the same species as Benkert's? Does anyone know if it was ever found again and/or named?
Thank you for any advices.
Viktorie
