Ciboria? species on crocus
Ralph Vandiest, 29-03-2015 21:03
Ralph Vandiest

Hello,


I found this species on 1 year old crocus litter that I put into a culture since 3 months. Stem 1cm high, cup 1,3mm wide. Spores 1 septated with guttules, J+. Spores 13/16x4,5/6µm, asci 8 spored and measuring 153/196x8/11µm.


Any suggestions?


 


Regards,


Ralph

Re : Ciboria? species on crocus
Did you look at the excipulum, is it of globose or prismatic cells?

Hello Zotto,
I didn't look at the excipulum as I didn't thought it was of interest for this species. Hopefully I still find some frb as last friday I only had 2. Can you tell me what this eventually could be?
regards,
Ralph

Re : Ciboria? species on crocus
The spores remind me of Rutstroemia calopus/paludosa, a species aggregate adapted to monocots. But such long stalk is irritating. Rutstroemia has a t. prismatica, partly with gel. Ciboria has globular cells and usually almost eguttulate spores, not such medium-sized drops as here.

Please look also at the substrate whether there is some blackish stroma or sclerotium.

Re : Ciboria? species on crocus

Hello Zotto,


Substrate is covered all over with black sclerotium/stroma (see picture 1 where you see in the bottom 2 black dots on the leaves). I noticed this a few months ago and that's why I put the crocus litter in a humid culture. Can the artificial culture cause the long stalks as the culture was in a rather dark box with limited light access?

Hello Zotto,


I looked at another frb and adapted also spore size. Frb had also a long stalk. <attached some more pictures.

Re : Ciboria? species on crocus
So it is prismatica to porrecta, somewhat gelatinized. Also the crystals speak for R. calopus/paludosa. I also thought that the stalk length might be due to less light and high humidity. But what is problematic: that species is more or less without stroma!

As it seems your fungus has no croziers, it should be R. paludosa (= henningsiana). But the stalks.....

Re : Ciboria? species on crocus
Hello all,
why not ? Now and then I have found the species with long stalks, the habitat was not so much wet.
Greetings Peter.
