Hymenoscyphus scutula?
William Slosse, 09-07-2017 10:27
William SlosseI found following species in damp litterlayer in Alnuswood growing on dead remains of Rumex sp stems.
- spores: hyalien, fusiform (?), filled with many tiny drops, 20.61x4.17um
- asci: uni to biseriated, 85-83 x 8.5 um, no crosiers
- paraphyses: slender, slightly thickened to the tip
Can anyone confirm if i'm wright?
Thx in advance,
William

Re : Hymenoscyphus scutula?

Hello William,


yes, surely a member of the H. scutula-complex.


Typically, H. scutula ss.str. has cilia at the ends of its spores, they are sometimes difficult to see. But there are similar forms without, called H. vitellinus. I am not sure if there is actual research about this, so I don`t know if vitellinus is a good species.


Best regards from Lothar

Re : Hymenoscyphus scutula?
Hallo zusammen
I am not very sure from the photos that the spores are scutuloid. They are mutliguttulate which is not very typical of H. scutula. So I cannot exclude H. menthae (= H. consobrinus).

The H. scutula aggregate is still unclarified, an there are only few sequences so far.

Re : Hymenoscyphus scutula?
Thx for your quick feedback, Lothar.
I couldn't find any cilia therefor I doubted.
Best regards,
William

Re : Hymenoscyphus scutula?
Thx for your interesting remarks.
I will look further on that species and compare it with the records of menthae.
Best regards,
William

Re : Hymenoscyphus scutula?
Hi William,

I agree with Zotto. The guttulation of the spores excludes H. scutula ss. str. as well as its form without cilia. Spores are typical H. menthae, as well as the white stipe of the apothecia. That single scutuloid spore does not belong to this species.
Moreover, in Belgium, we collect H. scutula not earler than in the second half of August.

Hi William

I just made a mistake in replying your request about an orange discomycete on Research gate.


Please send me a link to your fungus.
