Three Hyphomycetes on Verbascum
Florian Prell, 21-06-2016 15:05
Florian PrellHello Together,

last week i found a few interesting fungi growing on dead culm of Verbascum cf. thapsus near of Gießen, Germany. I checked three of the hyphomycetes for their microscopic features and need a confirmation or name suggestions for them.

The first one should be nothing else than Dendryphion comosum, the second one should be a Periconia sp. (maybe Periconia byssoides?), growing together with Lachnella villosa. For the third one i have no idea for a name and even if it belongs into a genera of hyphomycetes. The last one was growing on the outside of the old inflorescence of the Verbascum. 


Has anybody any idea, especially for the species of Periconia and the unknown fungus? I can also show more details and give more information for every fungus if necessary.

Thank you very much in advance,
Florian

Re : Three Hyphomycetes on Verbascum
Hello Florian,

The last fungus in your set is a species of Scopinella, possibly S. solani.  Scopinella species are ascomycetes with asci that dissolve within the centrum.  The ascospores are barrel-shaped with terminal germ pores.

Re : Three Hyphomycetes on Verbascum
Hello David,

thank you very much for your help! Is the distinct Ascocarp typical for S. solani?

Best regards,
Florian

Re : Three Hyphomycetes on Verbascum
Hello Florian,

Yes, yours has ascocarps typical for species of Scopinella.  All the species I have seen have a long neck like that.

Re : Three Hyphomycetes on Verbascum
To my knowlege, Scopinella species are not host-specific. Your first picture clearly shows Torula herbarum.

Re : Three Hyphomycetes on Verbascum
Hello David, Hallo Walter,

thank you both very much for your help. Of course Torula herbarum fits much better to the number one when i compare the material that i can find in the internet:-).
Is there any microscopic possibility to clearly identify the Scopinella on species level or is it necessary to do the cultivation? 

Best regards,
Florian

Re : Three Hyphomycetes on Verbascum
Hello Florian,

There is a discussion of Scopinella on this forum at http://www.ascofrance.fr/search_forum/8198.  Perz Piotr provided a key to species there.

Re : Three Hyphomycetes on Verbascum
Hello David,

thank you very much for the link, it is really helpfull.

Has anybody an idea, if the number two might be Periconia byssoides? 

Best regards,
Florian

Re : Three Hyphomycetes on Verbascum
Hi Florian

It appears pretty typical of Periconia byssoides. At the bottom of the photo showing the conidiophore there appears to be a ring of conidia below the head, as well as the group on the apex. That is characteristic of P. byssoides, the ring of conidia should be below a septum, which I cannot actually see, so worth looking for. The spore size is OK as well, 10-15 is given in E&E. 

All the best
Vivien

Hello Vivien,

thank you very much! I will check the collection again for the septum. 

Best regards,
