Lasiosphaeria-like
Gernot Friebes, 02-02-2015 13:37
Hi,

I would need your help with this Lasiosphaeria-like species that grows on a decorticated piece of Picea wood. I looked through the literature but couldn't find a species with the combination of brown, non-tapering ascospores with up to 7 septa and sulcate ostioles. Here's a short description by the person who collected this species (and took the photos):

Asci biseriate, without or only with weakly developed(?) subapical globulus. Ascospores brown (already inside the ascus), ca. (60)70-72 x 8 µm, bent in the lower third, with up to 7 septa, germinating when old. Setae dark brown, thick-walled.

Thank you and best wishes,
Gernot

Re : Lasiosphaeria-like
Hi Gernot,
I think it belongs to the Lasiosphaeris hirsuta complex. With such a stout conical and sulcate neck, it used to be called L. tuberculosa but the morphological traits largely overlap between the four species involved and for the moment there is no molecular support to merge or segregate them. Unless Andrew has new information?
Cheers,
Jacques

Re : Lasiosphaeria-like
Hi Jacques,


thanks! I have seen quite a few collections of L. hirsuta agg. but never with such a sulcate neck like in this find, hence why I didn't make the connection. The ascospores clearly fit the L. hirsuta complex well!

Best wishes,
Gernot

Re : Lasiosphaeria-like
Unfortunately, there is a wide range of morphological variation within the 8 species that occur in the L. hirsuta species complex.  This morphology overlaps among species making it difficult to distinguish species based on morphology alone.  Not what taxonomists like to hear...
