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 http://www.mycobank.org/MycoTaxo.aspx?Link=T&Rec=283905 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.
