The globular ascoma are small 2-5mm in size, reddish brown to dark brown.
Asci: 8 spored, IKI +ve (faint diffused), pleurorhynchus, large 287-327 x 25-33µm
Paraphsis: Thin, very abundant
Spores: Rounded and echinulate. Different stages of maturity observed in same specimen. An outer layer is present at the immature stages. Size: 18.2-20.7 x 17.5-20µm measured inside ascus - no free spores observed.
My initial suspicion is on Sphaerosoma echinulatum but the spores are quite smaller, perhaps because not fully mature spores have been measured?
What do you think?

Re : ID help - brown globules
Very interesting. I first thought of Ruhlandiella berolinensis with a similar spore size. The spores of this taxon are reticulate, anyhow. ...
Best regards from Lothar

Re : ID help - brown globules
I think this is a Boudiera species.

Re : ID help - brown globules
Thanks for your input.
I argee Nicolas, it is probaby a Boudiera or somethin close.
The taxon Sphaerosoma echinulatum Seaver was transferred to Boudiera by Seaver himself.

Re : ID help - brown globules
Thanks Lothar - as you say there is no reticulation on the spores.
I have looked at some species of Boudiera, as suggested, but I am having some difficulty to match it. Apart from the smaller spore size, the paraphyses in my specimen are thin and uninflated (4-5µm). There is also the question of the asci being pleurorhynchus. Boudiera acanthospora, B. areolata and B. tracheia are all aporhynchus. Now I am looking for info on B. denisii to compare.
Could species in the same genus have different ascus development/attachment?

Re : ID help - brown globules
Yes, there are both kinds of base in one genus, e.g. Aleuria (A. aurantia = simple septate, others with two septa) or Peziza (small group of simple septate species). If such genus is still monophyletic, that's another question.
