Hi to all: I'd like to know your opinion about th
Found ascomycete growing on leaves of Acer.
I think it is Microthyrium sp.
Any idea?
Thank you, best regards
Susana
there is a key to (British species at least) of Microthyrium at: http://www.fieldmycology.net/FRDBI/..%5Cgbchklst%5Ckey.asp?KeyID=14??
it is hard to see from the photograph - do the spores have appendages? if so are they apical or lateral; the only Microthyrium I have recorded on an Acer (A. pseudoplatanus) was M. microscopicum
best wishes
Chris
The spores had no appendages or cilia.
The substrate was Acer campestre
Thank you for the key.
I been able to find descriptions and a key in Ellis, JP 1976. British Microthyrium fungi species and like. 67 (3) :381-394; http://www.librifungorum.org/Image.asp?Nav=yes&FirstPage=243479&LastPage=244008&NextPage=243842
My collects all data agrees with Microthyrium fagi, JP Ellis M.fagi 1976, including the presence of dark collar.
I think between the two keys there is a discrepancy between the species M. fagi and M. inconspicuum, at least in the presence or absence of darker collar.
regards
Susana
