fungus on rabbit dung
Sven Heinz, 11-08-2018 19:10

Hello together,

does anyone have any idea what this is about. The fungus grows superficially on rabbit dung.

Spores: 14 - 15 x 4 - 5 µ striped.

Greetings Sven

Hello Sven..
This looks like a species of Myrothecium, possibly M. cinctum.

Hello David!

I did not know that the genus Myrothecium could also come on excrement; do you know if some species are more related than others to this substrate! Would you have a paper on this and a key?


Michel.

Re : fungus on rabbit dung
Hi Michel..
This is just a guess.  It's difficult to tell from the photograph, but it appears that the fungus was growing on a leaf attached to the dung.  That would be consistent with the usual habitat of Myrothecium species, which is soil and plant drbris.  The elongated and striate conidia are similar to those photographed by Matsushima (Fungi of the Soloman Islands) and described as M. longistriatosporum Mats. Domsch and Gams later considered Matsushima's species to be synonymous with M. cinctum.

I don't know of any specific records of a species of Myrothecium on dung, but cellulolytic and litter-decomposing species sometimes appear on that substrate even though they are not primarily coprophilous.

Tulloch's monograph of Myrothecium in Mycol. Pap. CMI. 130: 1-42 might have some records on dung, but I don't have access to that paper and, as far as I can tell, it is not available online. 

Kind regards,
David

Hello together,

thank you for the interesting contributions! Maybe someone still has literature about this fungus?

Re : fungus on rabbit dung
Here is Tulloch's paper

No mention of dung as far as I can see, but as David suggests M. cinctum, as a cellulose degrader, appears to have a very wide geographical and substrate range.

I hope this paper might be of interest in any case . . . .

Re : fungus on rabbit dung
Thanks Chris.  Even though there are no specific records on dung, M. cinctum still looks close. Sven's collection is not really synnematous, but it does have a short stipe.
