Hypocreales?

Bernard DeclercqHi,

I recently collected a species, on decayed wood hidden in a wood pile, that troubles me as the materal is immature and asci/spores absent of difficult to observe:
Stromata broady stalked to turbinate with flat disk, 1,4-3 mm diam., 1-1,2 mm high, olivaceous blue, with dark green-blue ostiolar dots which become projecting and dark brown when mature, senescent stromata blackish.
Perithecia arranged in one layer, 0,33-0,36x0,16-0,18 mm, with peryphysoid protruding ostioles 60-70 µm diam. Asci cyl., 8-sp., sp. 1-ser., eg 105x5 µm. Spores ellipsoid to ovoid, smooth, olivaceous grey, 9,5-11,5x4,5-5,5 µm, filled with minute guttules.
Thanks for your help.

Bernard

Re : Hypocreales?

This should be Sarawakus britannicus.
Best wishes,
Hermann

Re : Hypocreales?
That means we have now a name also for this fungus presented by John Leach?

Re : Hypocreales?
No, that appears to be something different, Sarawakus is not a discomycete, Sarawakus britannicus is like a typical green-spored Hypocrea, apart from 8-spored asci. Phylogenetically it falls within Hypocrea/Trichoderma and will soon be a Trichoderma (Mycologia, in press)

Re : Hypocreales?
I don't think that John Leach's fungus is a discomycete. It was considered a Hypocreales too by Roy Anderson and Thomas Laessoe, but as it was immature there was no final idea.

Re : Hypocreales?
Did not look at the whole conversation on the fungus, just on the pictures - the spores figured by John Leach don't fit at all for Sarawakus, but as the fungus is immature one has to leave it open...

Re : Hypocreales?
Thank you very much, Hermann. On the field, I was convinced to have collected a Hypocrea (wood piles!). I have been looking in the many extensive recent papers related to Hypocrea but did not find any species fitting my data.
