A Calycina like helotiale
Michel Hairaud, 06-12-2016 09:26
Michel HairaudBonjour,
I am puzzled with this late collection of a Calycina like helotiale on Dipsacus old stems.
MAcro and micro would rather fit with C. pseudodisrceta, including spores but the paraphyses content doesn't.

Ascus 70-80 x 5,5-6, H+ (though not easy to notice) , IKI +B, rather Calycina-type
Spores mostly 9-10 x 2,2-2,5 , OCI 2 , never septate.

This fungus looks as a mixture of Calycina, Cyathicula or even Phaeohelotium.
I will appreciate any help.
Amitiés. Michel

Re : A Calycina like helotiale
Hi Michel
how gelatinised is the excipulum? 
I think it is a subsessile Cyathicula.

Re : A Calycina like helotiale
Many thanks, Zotto,
It is stiptate , though shortly and you are wright, the excipulum is - at least- partly gelatinized.
here are pics of the medulla (clearly intricata), the outermost ectal and of a part of the excipulum more downwards.

Re : A Calycina like helotiale
Yes, strongly gelatinized in ectal, and typical guttulate cortical cells.

Re : A Calycina like helotiale
So, may be Cyathicula dipsacea as a tentative name ?

Re : A Calycina like helotiale
This is a big question, Cyathicula is a mess. The spores look unusual with their contents. Hmmm.
