Observation 21082: Mycena (Pers.) Roussel

This group of fungi were located on an old dead moss covered log, but were on the underside of the log. The colouring of the caps was a light brown tending toward the red spectrum. (depending where the light shone on the caps. The more mature caps were about 15mm across. The stipes were exceedingly long by the norm, and when broken away from the log, oozed dark blood like liquid. The gills were white as shown. The caps and stipes were dry to touch. The stipes were delicate.
There were several groups of this fungi on the same log in clusters of about 4-8 fruiting bodies. I thought they were " Mycena clarkeana " but my notes do not mention the stem bleeding event and the gills in my example are white not coloured similar to the cap, (as in Mycena clarkeana.") Unfortunately I do not have a good resolution image of the stipe.
The bleeding of the stipe and the length, are the best pointers for identification, I think. As usual I need help on this one. .
I have added some more images that I took of some of the other groups of fungi on the log. One of the images shows a twisting of the stipe, but this may not always occur. It may have been caused by the physical position of the other fungi in the cluster. The stipes are shown a little clearer in the additional images.

Mycena haematopus

Noah is correct in his comment. I have looked up the references he has pointed to and there are two names that can be added to " Mycena " in Australia..
I am waiting on his reply to what we might use. "haematopus " appears to be a carry over name from the Northern hemisphere, that incorrectly I used for our continent. Cheryl Grgurinovic has listed them as… (Galactapoda & Sanguinolentae.)

As far as I know

Mycena haematopus doesn’t occur in OZ… but there are a couple of other bleeding mycenas that do.

First, I’d check to make sure that haematopus actually exists in OZ…….

(anybody have an Australian field guide or species list? then, that there are no lookalikes.
we have at least two bleeding mycenas in N. CA, and i have no idea how many you have, Ian.

well there may very well be an australian version of this that varies somehow.

your mushrooms do look like haematopus, but there are some variants sometimes like Coprinellus micaceus over here is usually Coprinus truncorum over there.
they may be the same genetically and vary in basidia/cystidia/spore size or something and be named something else.

definitely a bleeding mycena either way.
