Unknown hairy conidioma on grass
Garrido-Benavent Isaac, 02-10-2014 11:14
Dear all,

This is an unknown conidioma (may be an acervulum) with long hairs that grew on a dead grass in Castro Laboreiro (Portugal).
It was about 300 microns long and 220-250 microns in height. Black, long, septate hairs covering the whole pycnidium wall (300-560 microns long and 7-11 microns wide).

Conidia hyaline, 11.6-13.7 x 2.5-2.8 microns (without appendices), and up to 26.3 microns including the appendices.

I was thinking on a Colletotrichum species but I've not literature about it.
I will appreciate any suggestion.
Thanks!

Isaac

Re : Unknown hairy conidioma on grass
It is Dinemasporium strigosum (D. graminum).

You can compare your sample with  data from next references:

Duan, J.X., Wu, W.P. and Liu, X.Z. (2007) Dinemasporium (coelomycetes). Fungal Diversity

26: 205-218.

or
Webster, J. (1955). Graminicolous pyrenomycetes V. Conidial state of Leptosphaeria michotii,


L . microspica, Pleospora vagans and the perfect states of Dinemasporium graminum.


Transitions of the British Mycological Society 38: 347-365.


With best regards,
  Martin.

Re : Unknown hairy conidioma on grass
Dear Martin,

Many thanks for your answer. I've checked the keys provided in the first paper and my samples match quite well with D. strigosum.
Thanks for the literature provided!

Best wishes,

Isaac
