Why use the name Trichoderma for only one (or two?) of the former Podostroma, if it can’t be used for all of them?
Apparently, no Trichoderma anamorph is known for Hypocrea/Podostroma leucopus or Hypocrea/Podostroma nybergiana.
This means two different names for one genus… So silly.

Thanks, Irene

Thank you for a nice article. It predates the Melbourne Code and who knows how this should be called now. Adolf

What a mess! Disperse a monophyletic genus just to use older names of the imperfect state.
From the link Oluma & Adolf provided below.

(3) In the monophyletic genus Hypocrea, a name to be subordinated under the older anamorph name Trichoderma, as accepted by a majority of members of the International Subcommission on Trichoderma andHypocrea (ISTH), certain species lack an anamorph or have anamorphs quite different from Trichoderma. Would it not be the best solution to simply retain these in Hypocrea?

I was the botany curator of the Royal British Columbia Museum Herbarium (V) for almost fifteen years and I know well what should or should not go into the location name. On the other hand, you and other MO gurus should know that you can annotate other collectors’ location, but you MUST NEVER TOUCH the original one.

I picked the name Trichoderma alutaceum from Species Fungorum. I suspect that it is a correct name for this fungus, since according to the ICN (Melbourne Code), both anamorph and teleomorph stages should be referred to by a single name:

Mind you, the fungus itself doesn’t care, how it is called.

“Mixed forest stand” and ca. 5 mi up should not go in the location name

Why is Trichoderma (an imperfect name) used instead of Podostroma or Hypocrea ?
