Hysterioid fruiting bodies with long hyaline spores

Ethan Crenson, 09-03-2020 23:18

Hello all,

Found yesterday in New York City. They appear to be fruiting on a stem of Rosaceae (or perhaps Smilax?). The hysterothecia are erumpent from under the outer layer of tissue and are 2 to 4 mm long. The asci are IKI-, about 108-125 x 6-7.5µm. The spores are very long and narrow, hyaline, 1-3 septate 48-58 x 2µm. I see now how difficult it is to differentiate scolecospores from fragments of paraphyses, but I think I found the spores in cotton blue. Many of the paraphyses I saw were irregularly bulbous at the ends and multi-septate.

Any ideas?

Thanks in advance,

Ethan

Re : Hysterioid fruiting bodies with long hyaline spores

Hi Ethan,

Perhaps I know this species, because one of your countrymen has already found it. If you have enough fruitbodies, I would like to study it to compare (morphological and molecular data) to this one and to a second one that I found in French Guiana in 2018.

Best wishes,

Alain

Alain,

I'd be happy to send you half of this collection. Just let me know where to send it.

Regards,

Ethan

Hi Ethan, that looks rhytismatalean to me. If the host is Smilax you might find tendrils on it somewhere along the length of the stem?
