Tengo estos hongos que no puedo identificar, ¿Tal vez Lanatonectria? Los encontré creciendo sobre ascomas viejos de Cucurbitaria sp.
Ascomas de 0,2-0,4 mm de diámetro, globosos, ostiolados, de color naranja, generalmente cubiertos por un entramado de hifas blancas. Paredes compuestas por células de textura angular. Ascas de (102-)110-122(-125) x (11,6-)13,7-17,0(-18,2) µm, N = 19, Me = 117 x 15,2 µm, cilíndrico-claviformes, octospóricas. Ascosporas de (16,1-)17,9-22,7(-25,2) x (7,8-)8,2-9,8(-10,2) µm, Q = (1,8-)2,0-2,5(-2,7), N = 36, Me = 20,4 x 9,1 µm ; Qe = 2,2, irregularmente biseriadas al menos en la parte superior del asca, lisas, hialinas, con un septo transversal, constreñidas en el septo, con los extremos redondeados o a veces terminados en punta.
Saludos.
Salvador.

Re : Nectriaceae
Hola Salvador,
Christian and I encountered this species repeatedly on Cucurbitaria. So did Walter and Hermann, most likely with the same species. It is an undescribed species of Macroconia (Wollenw.) Gräfenhan, Seifert & Schroers, segregated form Cosmospora by Grafenhan et al.(2011) in Studies in Mycology 68: 79-113, available online. Several different species might be involved depending on host affiliation.The type of the genus is M. leptosphaeriae that occurs on Leptosphaeria doliolum on Urtica, perhaps you know it from your region.
Cheers,
Jacques
