Relationship between the names is understood

The question is how do you tell them apart macroscopically or is it even worth the bother?

The second link that Walt provided shows an image similar to image 108104 and calls it the anamorph. However, when I compare all of the images on Mushroom Observer for these two names, I suspect that this is just a young sporocarp of the teleomorph. Of course it’s possible that it’s kind of like Xylaria hypoxylon where asexual and sexual spores are created on the same fruiting body just at different stages of maturity. The most distinct observation on MO in my view is observation 19742.

My general understanding of anamorphs is that they are typically undifferentiated and mold-like. MycoBank has some culture images on that based on my understanding is what an anamorph should look like. What I’m trying to understand is whether Sporotrichopsis terrestris is an exception and the anamorph is differentiated and macroscopically distinct from the teleomorph.

Until I get a clear rule describing when to apply each name, I’m going to call them all Abortiporus biennis and mark Sporotrichopsis terrestris as not for export.

Do we actually have pictures of both the teleomorph and the anamorph?

I don’t see a huge amount of consistent differences between the photos we have under the name Sporotrichopsis terrestris and Abortiporus biennis. Since anamorphs are supposed to be mold-like I’m wondering if all of the photos we have would be best called Abortiporus biennis since they seem more structured than a simple mold. Also with the new ICBN ruling (described here:, I expect A. biennis will become the name for the holomorph.
