Found on Saturday 4th July, parasitizing the fruitbodies of Kretzschmaria deusta. On site, viewing only with a hand lens, I thought that the very tiny spherical pink “balls” might possibly be something like an unknown (to me)
Nectria. Viewing the sample more closely at home, I then thought maybe a species of
Hypomyces. Under the scope though, no signs at all of asci. (and very few spores to be found, although I did eventually find some septate ones, shown in final image below).
The overall size of the orangey-pink area in first shot is about 25mm across.
Each individual sphere, is about 0.2 – 0.3 mm in diameter.
Any suggestions as to what this may be will be much appreciated.

Hi Mike almost certainly a
Hypomyces, but still with immature asci. As with many of the Hypocreales (including Nectriaand allied genera) the anamorphic state can be important. Not too easy to see here but the likeliest (not definite!) candidate appears to be the Cladobotryumstate of Hypomyces aurantius. Unusual host species . . . might be possible to mature it, you could try keeping it damp in the fridge.
Best wishes

Thanks Chris. Good to know I was on the right track – I don’t have any useful documentation on Hypomyces.
I’ve put the sample in the fridge, (on a piece of dampened kitchen roll in a sealed plastic tub).
I’ll keep an eye on it and post again if I see anything happening.
Regards,
Mike.

Just found this multi-access key to the genus viaASCOFrance: http://nt.ars-grin.gov/taxadescriptions/keys/FrameKey.cfm?gen=Hypomyces ” class=”bbcode_url”> http://nt.ars-grin.gov/taxadescriptions/keys/FrameKey.cfm?gen=Hypomyces Based on the info I could glean from your OP I worked on the principle of:
[list]- growth on a fungus (it seems not to include “pyreno’s” – but as I said this is an unusual host . . . )
semi-immersed perithecia
orange perithecia
hyaline conidia
one-septate conidia
[/list] and it came out asH. aurantius; hopefully you’ll be able to get more characters to gain a firmer ID. HTH
