Chaetosphaeria hebetiseta
Björn Wergen,

Hi there,I have an austrian collection of a Chaetosphaeria with a conidial state nearby identified as "Chaetosphaeria hebetiseta" (Réblová 2000). I am a bit unsure because I am not familiar with all the terms (locus, collarette, "proliferating sympodially") used to describe the conidiomata.
Spores 19-24 (28,5) x 4,4-6,5µm, 3septated. Asci 95-120x8-10µm. Conidia 2-3x1,5µm. On dead Fagus wood.
With the key I clearly come to the branch C. innumera - C. hebetiseta. The first one is described as having distinctly smaller spores and asci, and C. hebetiseta fits well with nearly all characteristics (the conidia are given as 1-1,5µm longer).
Perhaps someone can confirm the determination.
Thanks in advance,
björn
