Lasiobelonium (?) sur Rubus sp
Louis DENY, 09-12-2024 11:26
Hello forum

Sur tige morte de Rubus sp. Récolté à Belfort (Est de la France), altitude 450m, terrain acide. Diametre de 0,5mm. Couvert de poils bruns flexueux; réceptacle jaune vif. Spores 18-22 X 4,5µ, guttulées, 3 fois septées à maturité. Asques 100 -110 X 14µ, BB au Lugol, spores bisériées, Paraphyses à guttules dans la partie supérieure; Les poils me conduisent à Lasiobelonium, mais je ne vois rien qui colle vraiment, notamment du fait de l'habitat et de la couleur de l'hymenium,

Merci de votre aide

Cher Jacques!

I was waiting since a very long time for a new collection of this species. In 2002 I wrote an article about it based on collections from Montargis. The article is in German but I have an English translation.

Re : Lasiobelonium (?) sur Rubus sp
How abundant is your collection. I would highly appreciate if someone would be interested to sequence it, because nothing is in GenBank. In the Estonian herbarium TAAM is a collection from Devonshire by Graddon made in 1984. Not sure if Kadri obtained a sequence (KL 85). My guess is that the species belongs to Pezizellaceae.

I am further unsure if the correct name is Tapesina or Velutaria griseovitellina, which seems to be a difficult nomenclatural question

Thanks for détermination !
I have one single cane of Rubus, with about 10 apos. Ready to ship to whom wants it.

Great thanks!

Sorry Luis for my weird address, but I am also sometimes called Otto after my father :-)

I will send you Kadri's address, she would be very happy.
