Very small perithecia
Stefan Blaser, 28-02-2013 21:28
Hello everybody

It would be great if someone had an idea about this pyrenomycete.

It is on bark of a small branch of deciduous wood. The Perithecia are only 0.2-0.3 mm in diameter and about 0.2 mm high, black and rounded to conical. There is no pore visible.
The spores are rather special, thats why I think it could be identified:
Spores 60-85 x 3.5-4.5 micros, broadly rounded at one end and tapering to the other, rather pointed end, giving them a slender club-shape (see Photos), hyaline with about 6-8 transversal septa and filled with small oildrops, which makes the Septation difficult to see. The pointed half is sometimes strongly bent. Asci 110-125 x 10-12 micros. Paraphyses(?) densely packed, septate.

Thanks for any Ideas
Stefan

Re : Very small perithecia
Hi Stefan,
at first glance I think you should look into Tubeufia or something close.

Re : Very small perithecia
Hi Jacques
Tubeufia seems a good Genus to start with. Thanks a lot.

Re : Very small perithecia
Hi Stefan,

why not Tubeufia corynespora? If no setae are found, I think this should fit.

regards,
björn

Re : Very small perithecia
Hallo Björn

Danke für deinen Hinweis. Hättest du eventuell Literatur zur Gattung (Gattungsschlüssel?), oder zur Art Tubeufia corynespora für mich?

Liebe Grüsse
Stefan

Hoi Stefan,

schau mal hier: / look here:
http://www.mycologia.org/content/96/3/667.full.pdf+html?
Da findest Du auch einen Schlüssel zu Tubeufia-Arten.
There you'll find a key to Tubeufia species.
Grüezi,
Karl

Re : Very small perithecia
Hallo Karl

Vielen Dank für deinen Hinweis. Die Arbeit hatte ich auch schon gesehen. Leider ist da Tubeufia corynespora nicht ausgeschlüsselt (Die wird neu als Thaxteriella corynespora gehandelt). Ich habe die Art nun Anhand von Munks Originalbeschreibung als Tubeufia corynespora bestimmt.

Liebe Grüsse
Stefan
