Phaeohelotium terrestre?
Edit Szilvásy, 07-12-2014 19:07
Edit SzilvásyHi all,

Today I found this asco on the ground in a field.
I think this specimen as Phaeohelotium terrestre based on the habitat.
There is no description in my books.
Where can I found some info about this specimen (spores, etc..)?
Spores 12-15 x 3-4 micron, paraphyses quite slender.
Thanks, look forward to your help.

Re : Phaeohelotium terrestre?
Dear Edit

Ph. terrestre has much wider spores and is confined by mycorrhiza cto Myrtaceae such as Eucalyptus, and Nothofagus.

Yours could have grown on organic particles in the soil. It reminds me of Ph. monticola. Did you test IKI reaction? The contents of the living paraphyses would be helpful too.

Re : Phaeohelotium terrestre?
Sorry, I made a mistake: I confused Ph. terrestre with Discinella terrestris = Ph. baileyanum.

Ph. terrestre (Velen.) Svrcek is a possible synonym of H. epiphyllus or perhaps Ph. monticola, in my opinion.

Re : Phaeohelotium terrestre?
Dear Zotto,
Nothing happened.
At least I heard the news of the Ph. baileyanum. :-)
Today I was in search of new asco, but I could not find. (The rain has rearranged the habitat.)
I have noticed that there is an oak tree five meters from the asco habitat. I think they could have grown on organic particles of oak.
Thanks for the information about synonyms.
Friendly greetings,
