On Yucca filamentosa - conidia like Robillarda, but aseptate

Ethan Crenson, 08-05-2025 18:32

Hello all,

I was looking at leaves of Yucca from a NYC coastal park recently and encountered conidiospores that looked interesting to me. They are associated with pycnidia which form on the leaves, but it is likely that the pycnidia are a separate anamorphic taxon with brown conidia.

Hyaline conidiospores with a lot of oil content. Usually five or more hair like projections extending from one end of the conidia. 35-50 x 10.8-12.1µm. They bear a resemblance to Robillarda species, but that genus has 1-septate conidia, I think. Pestaloziella spp. are also similar, but have hair-like projections that branch, while my collection has individual hair-like projections.

Can anyone recommend a genus? Thanks in advance.

Ethan
