Small Grey Ascomycete
David Kelly, 03-07-2012 12:43
Hello 

I'm in the South of England, in the area of The New Forest. I was looking at a Russula on grass and moss on my lawn when I saw a small (up to 5mm) grey ascomycete.  It was slightly curled but not cup-shaped. The hymenium was grey. There were no hairs around the edges but hairs covered the underside.

The asci had eight  ascospores  and the ascospores had two oil drops, measured 23 X 15 and appeared to be irregularly warty with small warts but there is some question whether this is pseudo-reticlation. Spores that were relased in a spore print were measured. The first photo's are in water and the next are in Cotton Blue.

The spore size points me to Trichophaea woolhopeia the reticulation points to something like Trichophaea variornata.

I'm new to the study of fungi.

Here are some photo's

Hi Dave,
 
For me, this is T. livida. However, the spore dimensions are slightly too large, but the rough warts are suitable for this species. The spores of T. pseudogregaria are only slightly punctured.

Peter

PS:   It can also be a tiny copy of Humaria hemisphaerica. Since the spores would also fit dimensions.

Re : Small Grey Ascomycete
Hello Peter,

many thanks for the reply. That is interesting because the naturally shed free-spores, measured in water did look like they had expanded and quite a few burst. The few spores that I measured in Cotton blue, like the one in the third photo from the end, measured 21 X 12 but I do understand that Cotton Blue kills the spores and they can shrink. I can only find one photograph of T. livida on Google but it does look the same.

Re : Small Grey Ascomycete
Hi Dave,

Macroscopic view this ascomycete all the same. The ornamentation of the spores must be examined. Can you send me a piece?

Re : Small Grey Ascomycete
Hello Peter,

I have a body left that is still fresh. I can send it to you. Should I dry it first or send it fresh?

Re : Small Grey Ascomycete
Hi Dave,

I have examined the Trichophaea. I'm only a result of
T. cf. pseudogregaria because
the spores not almost spindle-shaped. (As specified in Bronkers, I do not own
proof)T. livida has warty spores.


Peter


PS:   Would you back the rest, Dave?

Re : Small Grey Ascomycete
Many thanks for your efforts Peter.


No, I don't need it back .


Regards

Dave
