Scutellinia
Ismael Wind, 24-04-2012 00:29
Hi everyone. Today I found what i thought was an Melastiza chateri. But once under the microscope it turned out to be a Scutellinia. The spores were ca 20 * 12.5 lots of droplets. I could not find any ornamentation, yet.. The parafyse were very bendy, the knob was ca 10um. The hare's up to 650. I wonder wich one it might be? Surely not S. scutellata? It wasnt growing on wood but on bare ground between mosses, aon a wet place, sandy. It was newly created nature, also a lot of omphalina chlorcyanea and Discinella menziesii?. (Roseodiscus) Anyone any thoughts? Micropicture will follow later

Hi Mr. Wind!

:-)

When making micropics, make sure to use Cotton Blue preparation, especially with mature ascospores. The apothecium whose sections readily ejected spores when observed in tap water with no pressure applied should be used for subsequent CB preparation so that you can be sure you are dealing with completely developed spores. It is critical for identification of an Scutellinia species. When making CB prep. make sure you also include finely sectioned margin. The contrasted marginal hairs would reveal also the structure of their bases - also crucial for identifying the species!

I will also send you an e-mail soon regarding our older issue!

Cheers,
Neven

Re : Scutellinia
Adio I ;)

Is it found in Netherlands ? Near sea ?
After your first microscopic research, is it possible to ask you a part of your collection ?
We'll look forward your microphotos.


Read you soon,
Beñat

Re : Scutellinia
the Netherlands is always near sea ;-), joking aside, no it was not near sea but near a small river and in the Netherlands indeed.

Unfortunally i do not have CB yet, hopefully thursday. But i made micropictures anyway. The ascus is 275 long. SPores seem to be larger then mentioned, 22.5 * 12.5. The hairsbase is bifurcate

ps Neven i loke forward to youre mail!

Re : Scutellinia
Adio I,

It's difficult to say anything just with this. Scutellinia is a difficult genus. It is important to have :
- sporal ornementation (in CB, like Neven said)
- hairs measures
- hairs base (here, we can see bifurcate but are you sure that all have bifurcated bases ?)
Your spores measurements can't help us because 20-22 x 12 are the most common measures in this genus...

Read you later,
Beñat

Re : Scutellinia
unfortunally its going to be sunday before i can look at it. I will send it to you benat, if you give me youre adress in a personal message
