the info they give about the nomenclatural rules is wrong.

International Code of the nomenclature is available online

It is a nice reading.

Is there a part of the code that says we should treat all taxa originally described with single “i” endings, as orthographic variants? e.g. Hygrocybe singeri

*edit. Here is the answer to my question: "Specific names honoring people follow a few general rules, such as adding -i to a name ending in ‘r’ or a vowel other than ‘a’ (palmeri, covillei),……A final note with regard to the use of the -i or -ii ending is that the 1993 Tokyo International Code of Botanical Nomenclature (ICBN) has recommended the use of -i for all specific epithets based on “classical” names, thus wislizeni instead of wislizenii and maximiliani instead of maximilianii." Names ending in -y also require only a single -i. Since “rodman” is a modern name that does not end in -r or -y, -ii is the correct ending.

Why so much ado about nothing? Megallodonta rodmanii (with double i) is correct and you don’t have to waste your time wondering about it.
To treat the orthographic error (“rodmani”) as a deprecated sysnonym is ridiculous.
See The Code:
32.2. Names or epithets published with an improper Latin termination but otherwise in accordance with this Code are regarded as validly published; they are to be changed to accord with Art. 16–19, 21, 23, and 24, without change of the author citation or date (see also Art. 60.12).
