The conidia possibly had faint ornamention, as did sections of the hyphae, the conidia was 3 - 4 um and the average was 3.05. No clamps or reaction with melzers were observed.

Re : Mold on Agaricus xanthodermus
Good evening,
This looks like a species of Penicillium to me. Penicillium brevicompactum commonly grows on defunct agarics but has smooth conidiophores, unlike the roughened ones in your material, which remind me more of P. aurantiogriseum. It seems to be a member of the sugbenus Penicillium, which is thoroughly monographed by Samson & Frisvad http://www.cbs.knaw.nl/publications/CBSPublicationDetails.aspx?Rec=1049?.

Re : Mold on Agaricus xanthodermus
Hi,
Thank you for the information and for the amazing link, I looked quickly at the pdfs, but much of it went over my head. It will take some time to study them enough to attempt an identification, especially since I do not currently have the skills or materials to make a culture or many of the chemicals that seem to make the identification process easier. :)

Re : Mold on Agaricus xanthodermus
I would like a copy of this publication - the URL has been changed since then. I am working on a similar Penicillium. Thanks!

The Westerdyke Institute has changed since our conversations of 2012. These three papers should have the most up to date information:
