Recognized by sight: occurrence on non-bamboo substrate. unclear to what extent A. philodendri is a distinct sp.

and I don’t take that substrate to be bamboo anymore. if correct, that ought to make this either A. moellerianus or A. philodendri (to the extent that they are not the same thing), or neither.

from the Mycologia article:

“Although originally considered pathogens of their plant substrates, many members of Clavicipitaceae have been found to be pathogens of homopterans (e.g. Coccoideae) that spend the majority of their life cycle attached to their plant host (Petch 1921, Hywel- Jones and Samuels 1998, Sullivan et al 2000, White et al 2002)."

The inferrence is that Ascopolyporus is one such genus, though the article never says so explicitly. Fascinating stuff. Entomopathogens given residence in the tree spp. with which they’ve developed a symbiotic relationship, constantly on guard against (and feeding off of) herbivorous insects.

All the Ascopolyporus

dwell on bamboo, with the exception of A. philodendri, described from specimens resembling A. polychrous but found growing on a Philodendron sp.. The striations in the stick seen here say bamboo to me, eliminating the oddball of the genus from the list of possibilities.

Under the remarks for A. philodendron’s maiden description it’s mentioned that it resembled A. polychrous in almost every way, save for some minor size discrepancies and the difference in substrate. One of those shared characteristics is purple coloration, which leads me to think that this observation may be of Möller’s A. polychrous.

I’m copying his original description as we speak for the ‘Notes’ section of its name page. We’ll see how it stacks up against these images once it’s finished.

As for the ‘polyporus’ part of the name, it has to do with the tiny pores produced on the underside of the fruiting bodies. While they superficially resemble the pores of a conk, they’re actually downward-facing ostioles inside of which the perithecia are formed.

This specimen is immature, so the pores aren’t fully developed. Larger fruiting bodies actually become shelf-/bracket-like with visible “pores” underneath (see Fig. 1 B in the Mycologia article)

amazing.

I get the asco part; why polyporus? and what is UP with that intense, purple interior color???

substrate?

nay

an asco. in the Hypocreales. the mycologia article breaks the group down pretty well. i’m still digesting it all myself.

Name suggests
