Teleomorph of Dendrostilbella smaragdina ?
Francois Guay,

I think I may have found the teleomorph of Dendrostilbella smaragdina.
It was growing on decaying conifer wood, next to the Dendrostilbella smaragdina anamorph.
Spores: 5.8–8.95 × 2.92–3.58 µm
Asci: 8-spored, IKI+, with croziers
Here is the iNaturalist link for photos: https://www.inaturalist.ca/observations/309564369
Has anyone else seen this species?
Thanks!

Re : Teleomorph of Dendrostilbella smaragdina ?
Very interesting case! I read in Seifert
that he wanted to describe the teleomorph in Claussenomyces.
In GenBank I find several iNaturalist ITS sequences of D. smaragdina which give this Blast result:
ITS: 97.3% Dendrostilbella sp. CA01, 94% Phialocephala virens, 90% Clauss. kirschsteinianus.
I will do a phylotree with these and come back soon.

Re : Teleomorph of Dendrostilbella smaragdina ?
Here is now the interesting result. With strong support D. smaragnida falls in a clade with what I call Resinomyces. But this group has always inamyloid asci, so I doubt if your fungus is the teleomorph.

Re : Teleomorph of Dendrostilbella smaragdina ?
Very interesting! Thanks, Zotto, for making this phylotree. This fungus could be something else entirely. I have seen another observation of D. smaragdina with these teal asco right next to it. Based on the microscopy, do you have any idea what genus it could be? I am sending it for sequencing and will keep you updated.

Re : Teleomorph of Dendrostilbella smaragdina ?
Oh you saw it twice! My idea was a Hyphodiscaceae, but that is a pure guess. Hyphodiscus smaragdinus has a somehow similar colour but of course tuberculate hairs.

Re : Teleomorph of Dendrostilbella smaragdina ?
Nice! It does look very similar to some Hyphodiscaceae. Thank you, Zotto, now we just need to wait for the DNA sequencing results!

Re : Teleomorph of Dendrostilbella smaragdina ?
Hi Zotto,
I got the sequencing results back for this species. It was sequenced using Nanopore technology, and I used only a single fruiting body in a microtube for extraction. It matches 100% with several D. smaragdina sequences, so it seems to indeed be the teleomorph of D. smaragdina!
here is the blast: https://mycomap.com/genetics/blast-search/hfsont54_its4-6_64_a8-dik-fg01-fg0313-inat309564369-hyphodiscaceae_-1-ric325-517558-r402290/

Re : Teleomorph of Dendrostilbella smaragdina ?
Great! So the connection is proved. Now the question is, if there exists an old description of the teleomorph.
How does whit MycoBLAST work? I opened the site but see no window to paste a sequence.

Re : Teleomorph of Dendrostilbella smaragdina ?
Hi Zotto,
I asked Keith Seifert whether it corresponds to the teleomorph he was referring to in his paper. I'll let you know once I hear back from him.
The MycoMap BLAST that I shared already shows the BLAST results from both NCBI and the MycoMap local database. If you want to run a new BLAST, you can click on MycoBLAST Search, and on the next page, on the right-hand side, click "Add New MycoBLAST."

Re : Teleomorph of Dendrostilbella smaragdina ?
This worked, great thanks! I tested it with my present project, Calycina albosanguinea, and got a 99.8% hit on iNat 188663364. How is it possible to retrieve the data from this find, even the sequence is not there.

You can download the FASTA file from this page. When you run a BLAST on MycoMap, you can use the iNat number as the query; that's how I obtained this BLAST.

Re : Teleomorph of Dendrostilbella smaragdina ?
I could extract it, from the xml file by renaming to txt. No idea how to open it. t has 1 nt difference to all other sequences of that species, perhaps an American deviation. Perhaps I can get the hiddne coordinates and finder name.
