Possible Calycellina from eastern Spain
Garrido-Benavent Isaac, 21-02-2014 12:12
Dear all,

I'm Isaac Garrido Benavent, from Spain. This is my first mail to Ascofrance. I'm looking forward to participate here, and learn as much as possible about ascomicetes.

I'm dealing with a species that supposedly belongs to the genus Calycellina, but I'm not convinced at all. It was found growing on dead leaves of Quercus coccifera in a ravine located in southern Valencia (eastern Spain) at 200 m asl. Some data:

- Asci 50-63 x 7-8 um, with croziers, with less than 8 spores (normally 6), abundant granular content, and a distinct apical aparatus which is shown in the photos.

- Paraphyses from 65 to 70 um length, scarcely septate, with somewhat widened apices up to (2)2'4-3'6(4') um (slightly clavate).

- Spores (12)15-17'3(19'4) x 2'5-3'6 um, fusiform, with rounded ends, slightly or not curved, non septate, hyaline, with abundant granular content and 1 to 3 greater guttules.

Excipulum hairs visible under dissecting microscope, 17-32 x 2'7-4'2 um size, greyish brown (somewhat yellowish in lugol), septate, apparently smooth, more or less cylindrical, tortuose, and with somewhat narrowed apices.

- Macroscopically, the diameter of the apothecia less than 2 mm.

Any suggestion would be appreciated. Thanks in advance!!

Regards,

Isaac

Dear Isaac

welcome to the forum!

I have no clear idea about your fungus although you show a lot of details. What I miss is a section of the excipulum, is it a gelatinized, and what cell shape ans colour.

From the hairs I actually suspect a Calycellina (or Phialina when accepting that genus). Important would be to study living asci and paraphyses/hairs. The latter might have contained refractive vacuoles, and the spore number would better be seen inside the asci (4-6-spored?).

Re : Possible Calycellina from eastern Spain
Dear Zotto,

Thank you very much for your answer. You provided me some hints on what characters are more useful for studying this group. So, despite the specimens are actually dried, I will try to get some of the relevant traits you told me as soon as possible.

Enjoy the weekend!!

Regards,

Isaac
