ID request: This specimen was collected in Malta o
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?
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
I argee Nicolas, it is probaby a Boudiera or somethin close.

The taxon Sphaerosoma echinulatum Seaver was transferred to Boudiera by Seaver himself.
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?
