Synnemata of Penicillium/Talaromyces on Hawthorn (Crataegus) fruit
Stephen Mifsud, 08-12-2022 09:10
Stephen MifsudIs there a specific Penicllium species like this growing on the rind of decaying fruit (not advanced state of decaying yet) of Crataegus monogyna?

I have not done any microscopical investigations, but perhaps some conclusion can be already drawn from the shape, feeding type and host specificity discussed here. I can do some basic microscopy later on.

I think I managed to have a pure culture (still 1cm wide after 3 days).

Re : Synnemata of Penicillium/Talaromyces on Hawthorn (Crataegus) fruit
Well, this should be a Talaromyces sp. - but I cant find much knowledge about synnemata species on fruit. Wondering if someone found something similar to compare.... Good Sunday!

Re : Synnemata of Penicillium/Talaromyces on Hawthorn (Crataegus) fruit
Thank you for this Przemek - seems we have same interest / 'hobby' !!

I am happy to see some of my Penicillium records and colonies match those listed in the document you kindly shared (Is that your work?).

However I think the one I found on Hawthorn is different from those in the doc because it formed distinct tufts (synnemata) while  those in the document are species with simple conidiophores. Also, my colonies have yellow-ochre areas - the same colour as the base/column of the synnematous growth.

For now I am happy that I have a pure colony and I will do more research in the coming days.

Yes, mycology is a great hobby. :-) Sorry, I didn't notice that I provided a link without authors.

Here is the public source:

Are you sure these fruits didn't pass through the fox's digestive system? It is somewhat similar to Penicillium vulpinum.
Regards, Przemek

I'm impressed with that website Przemek, the amount of info is incredible a mix of educative and taxonomic. Even if written in czech, i know I am going to use it. 

Your question is very easy to answer. The fungus was found on the skin (epicarp) of the fruit of Crataegus monogyna (Hawthorn) fallen from the tree and lying on moist ground in a valley, still reddish and intact.  In our country (Malta) there are no foxes or other mammals that consume this fruit. There were hundreds of fruits and about 10% where infected with this Penicillium.

Your suggestion is valid, it looks likes P. vulpinum (P. claviforme) but it is not copriphilous.

Thanks for messaging!
