<p class="MsoNormal">I was wondering if I could get feedback on some scary-looking growths on a few herpetology specimens in our collection (photos attached here). Any thoughts on what these residues are and/or advice on how to treat them would be much appreciated!<o:p></o:p></p>

<p class="MsoNormal"><b>Orange-brown bumps.<i> </i></b><i>(images 143927 and 143900)
</i>There are small, orange-brown, round bumps on one specimen that has had its tail exposed from fluid levels that are too low. I completely replaced the ethanol for this specimen and tried to gently scrape off the growth, but most of it was quite dried on,
so I left it soaking in fresh 70% ethanol for the time being. Is this definitely fungal? Should I try to scrape the rest of the growth off the specimen's tail or leave it alone?<o:p></o:p></p>

<p class="MsoNormal"><b>White layer of residue.</b> <i>(all other images) </i>On a few salamander specimens, there is this opaque, white layer of residue. This is occurring on salamander specimens that are completely submerged in ethanol. (However, I am not
sure what the concentration of this ethanol is or the last time that it was changed out; I worry it might have lost ethanol concentration over time.) Any thoughts on what this might be and how to treat it? <o:p></o:p></p>

<p class="MsoNormal">I took over this collection a few months ago, so I am still discovering issues with specimens. I appreciate any suggestions that you folks have to offer on how to help these poor specimens!<o:p></o:p></p>
