Observation 59051: Rhytidhysteron Speg.

When: 2010-10-25

Collection location: State Fishing Lake, Atchison Co., Kansas, USA [Click for map]

Who: C.Wick (C.Wick)

Specimen available

Unfortunately, I’m also not sure on the wood I found it on? There were several small downed branches that were NOT in contact with the groun that had these tiny cups on them. Rehydrated with rain when I saw this. I’ve been back twice after this collection and have not witnessed them so beautiful since.
When first coming across them, I thought the ‘lines’ were a type of cilica like the Eyelash cups have? But…once I got home, got the photos and looked at them under the magnifier…realized they weren’t.
Any suggestions would be GREAT here!

Schizophyllum commune is a rather notorious pathogen

that immuno-compromised individuals are more vulnerable to infections of all sorts, in THIS particular case, the patient was NOT immuno-compromised, but “merely” had diabetes and hypertension, along with a break in the skin and a stubborn, subQ infection with this fungus.

Fungi are opportunistic feeders; sometimes, we are the food.

is much more diverse/complicated than previously thought:


and also apparently has the ability to be human pathogenic in immunocompromised persons:

Can anyone give me links that are in English for this fungi? Everything I’ve found under either recent ID has either been in French or other…
Thanx again for the help! That parasite is nasty…makes me wonder if it is so prolific that it makes this particular fungi almost un-noticed because it’s too late to see before it’s devoured?

Neat fungus find C. Wick

Great ID Jonathan. According to the Cornell website it can be attacked by a parasitic fungus. Unguiculariopsis ravenelii subsp. hamata.

Have been driving myself nuts trying to get the name to this species and think I’ve driven everyone in my area nuts to do the same. Looks like it’s definately Rhystidisteron hysterinum. Thanx everyone!

nifty asco.

Does this help to get the ID? :o) Looking back on the dried stick I have right at hand…not all fold…but some have.

There is a crease down the middle of the red hymenium and they look like maybe they open and close like a taco shell.

Great picture..

Sorry no one could help you out on this. Dont think it is a scutellinia though, you are right. You think the margin would be definitive enough that someone could ID it though.
