Ophiobolus or Similar with Short Spores
Peter Thompson, 29-05-2014 15:16
Hello Everyone,

I have found fruit bodies of what I assume to be a species from the genus Ophiobolus. They were growing on a damp, dead, undetermined, thin herbaceous stem and on drying, the fruit bodies have collapsed noticably.

The Shoemaker 1976 paper does not seem to contain a species matching the characteristics of mine. I notice some clear similarities between the shape and structure of the spores of my sample and those of the 16th May 2012 forum post by Enrique Rubio, (which was concluded to be an undescribed species). In mine though, the partly swollen cell is at the centre of the much shorter spores.

I have attached an image of the fruit bodies and a sketch of the microscopy. I imagine that it will turn out to be another undescribed species, unless anyone can identify it.

Thank you,
With Best Wishes,
Peter.

Re : Ophiobolus or Similar with Short Spores

Hi Peter


This Ophiobolus (?) is a very common species that I found regulary on herbaceous stems (this week end also on Euphorbia stems) at Somiedo (north of Spain). But at this moment the fungus remains uncertain.

Re : Ophiobolus or Similar with Short Spores
Hello Enrique,

Thanks for your reply.

I am wondering if my find is different, because of the position of the swollen cell right in the centre of the spore. I am seeing both 5-septate and 6-septate spores, which, I think are shorter than yours.

With Best Wishes,
Peter.
