Orbilia carpoboloides ?
Ethan Crenson, 17-12-2019 05:50
Hello everyone,

I collected this in Central Park NYC yesterday.  I'm not sure of the substrate, but there are many old Elms in the area. It appears to be growing directly on the wood substrate, but also growing on a pyrenomycete which could be Nitschkia.  It looks a bit like Orbilia carpoboloides, though the spore dimensions are a bit off. Orange apothecia with a whitish crusty margin growing to about 1mm at the largest.  Asci are 57-70 x 4.5-5µm.  IKI-  Spores are almost seed shaped with long, worm-like bodies running near the narrow end.  7-9 x 3-3.5µm.  Paraphyses are bulbous at the ends with a narrow cap about 4µm at the widest point.  I can provide more images if necessary. Orbilia carpoboloides or maybe Orbilia flavidorosella? 

Thank you in advance.

Ethan

Re : Orbilia carpoboloides ?
Yes, it is O. carpoboloides (= O. piloboloides), and it is hardly believable that the long-spored samples reported recently are the same. But we found all intermediate collections as well.

The substrate really looks like elm. Could you please tell me the date of collection?

O. flavidorosella has only 1.8-2 µm wide spores and narrower paraphyses.

Re : Orbilia carpoboloides ?
Thank you so much!  This is new for New York City as far as I know at the moment.  Is O. carpoboloides restricted to Ulmus or does it occur on other substrates?  I'm curious also if there is a relationship with the pyrenomycete (Nitschkia perhaps) which it is growing on/with. 

The information about the collection... December 15. 2019, Central Park just inside the East 76th Street entrance at 5th Avenue. An ascomycete with a very posh address. A block from the French Consulate.

Re : Orbilia carpoboloides ?
We know samples from Canada and eastern USA, but not for entire New York State and adjacent US states. Ulmus  is a main substrate but there is also Salix, Cercis, Morus and various other special hosts, eve Passiflora.
