Immersed long-necked pyrenomycete - Ceratostomella (?)
Ethan Crenson, 06-11-2018 08:59
In New York City, on wet well-rotted wood.  A long-necked black pyrenomycete, with perithecia fully immersed in the wood.  Exposed portions of the beaks are shorter than 1mm.  Somewhat sulcate. Asci very short stipitate, spore portion 33-43 (-46) by 6-7 (-10)µm. 37-50 (-60)µm in total length.  Apical apparatus IKI-  refractive ring. Spores light brown in asci when mature with 2 to 3 guttules 7-9.5 by 3-4µm.  Hairs mostly unbranched, brown, septate, about 5µm wide.  This seemed similar to brown spored sp. in the genus Ceratostomella (s.l.) but I am uncertain.  C. rostrata seems to differ in spore size. Any help would be appreciated.

Thanks!

Re : Immersed long-necked pyrenomycete - Ceratostomella (?)
I would suggest to check Réblová’s 2006 paper on Cerastomella and related species. For instance, species of the genus Xylomelasma have brown spores and a sulcated neck. A later paper by the same author includes a key to more long-necked species.

Good luck, Eduard
