Cistella?

Dear friends,


While sorting my last year collections I've found a tiny disco with ornamented hairs on some dicotyledon (probably, Artemisia, but I'm not sure).


Fruitbodies are 0,2-0,5 mm, cream-coloured. Excipulum textura prismatica, hairs 12-55*4,8-5,8 um, warted in upper part.


Asci IKI blue, with croziers, 23-26*2,8-3,2 um. Paraphyses lanceolate.


Spores elongated, 5,8-8,2*1,6-2,2 um, with few small oil drops.


With Raitviir 2004 I got a Cistella hungarica.


With best regards,


Irina

Re : Cistella?
Hi Irina!

For me your find looks like Cistella grevillei (II).
You can search for flexuose hairs (it seems so in your collage the right picture) und blue medulla with IKI. But the hairs should be septated.

Re : Cistella?

Thank you, Ingo,


In Raitviir's (2004) description of C. grevillei spores are  longer (8-10 um) and the same goes for ascus (43-56 um long) and hair (30-75 um) size...


Tomorrow I'll check whether hairs are septate. 


With best wishes,


Irina

Re : Cistella?
I too would suspect grevillei . . . . see for example http://www.librifungorum.org/Image.asp?ItemID=36&ImageFileName=SyllogeFungorum8-407.jpg? the spore measurements given there are very close to yours

best wishes
