On Washingtonia

Enrique RubioPerhaps someone can help me to identify this pyrenomycete that grew gregariously on Washingtonia leaves, inside more or less circumscribed light brown spots. The asci appear bitunicate and the pseudothecia are very small, up to 150 microns in diameter, deeply immersed in the substrate, ostiolate and with an amber-coloured, non-translucent content. Pseudoparaphyses very few but perhaps present. Spores hyaline, naviculate, very guttulate, without septa.

Re : On Washingtonia
Olá Enrique,
Vejo que ainda não houve qualquer resposta ao teu pedido. Entretanto, eu mostrei a tua mensagem e as fotos a uma colega que trabalha com fungos em folhas de palmeira; disse-me que não existem quase registos em Washingtonia, seria interessantíssimo poder sequenciar esse fungo. Parecia-lhe algum Botryosphaeria-like, mas que era muito difícil perceber sem ter algumas características culturais. No entanto, os ascos são particularmente estreitos, o que o afastaria dos ascos de Botryosphaeriaceae, que costumam apresentar uma endotúnica bastante diferenciada.
Estarás interessado e poderias enviar uma amostra para obtermos cultura e fazer sequenciação? Se sim, dar-te-ei endereço.

Re : On Washingtonia
Hello Joao
Of course if you give me an address I could send you ascomata of this fungus. Our colleague Angel Pintos has tried to obtain pure cultures, but although the ascospores germinated well, the growth stopped and has hardly progressed.
thank you very much for your help.
