Lasiosphaeria ?
Ethan Crenson, 30-01-2019 19:38
In New York City last weekend I found these tiny brown hairy pyriform fruiting bodies on a branch of hardwood. They look to me to be something near the Lasiosphaeria hirsuta complex. In fact my collection looks a lot like one from 2015 by Gernot Friebes here on ascofrance (33494). However, microscopically, there are significant differences. Is it possible that my collection contains immature spores only?

The spores are 45-55µm and often bent. They are hyaline and guttulate and do not appear to have septations. The asci have a refractive apical ring but are IKI-, measuring about 161 x 12.5µm. Hairs are thick-walled septate and around 3.7µm thick near the base.

Thanks in advance!

Re : Lasiosphaeria ?
Lasiosphaeria hirsuta complex, as you state.  Lots of cryptic species here.
