Loculoascomycete on hardwood
Enrique Rubio, 18-04-2012 13:40
Enrique Rubio

Hello again

These nice, gregarious, small (0-7-1 mm), ostiolate, pseudothecia with conspicuous orange yellow neck that turns purple in KOH, grow under a dense, byssoid, ochracous subiculum on indeterminate wet hardwood in riversides.
Asci bitunicate, 8-spored. Pseudoparaphyses present. Ascospores 55-98 x 12-17, 7-septate, the fourth cell wider. Walls minutely verruculose in Melzer. 


I don't know a good genus for my collection.
What's your opinion
Many thanks in advance
Enrique

Hi Enrique,

looks quite similar to Pseudotrichia viburnicola.

Best wishes,
Gernot

Re : Loculoascomycete on hardwood
Bonjour Enrique,

Je suis d'accord avec Gernot. La représentation et description de ce spécimen(réaction KOH ,mensurations et cloisonnement des spores et asques bituniqués) convient
parfaitement pour Pseudotrichia viburnicola. On peu le trouver sur une large gamme
d'hôtes,sauf sans doute les résineux
Amicalement,

Paul LEROY

Re : Loculoascomycete on hardwood
Hi Enrique,

thanks for the data!
It turns out again that Pseudotrichia viburnicula is not very picky in choosing the host...

Best regards

Martin
