Found growing abundantly in every small patch of Casuarina equisetifolia duff mixed with wood chips under ornamental trees in a small area (Not C. equisetifolia, the duff was probably collected locally by the city). They deliquesced too quickly to observe cystidia on the gills or preserve them.
Spore range = 12 – 14 (18) x 8 – 9 (12) µ
Average spore = 13.05 × 8.75 µ
Q range = 1.33 – 1.63
AVerage Q = 1.49
2-spored basidia observed,
20 spores measured.

I tried to change the User Name “Byrain” into the “Smeghead” but the User Names are apparently protected and can be changed only by the users themselves.
Something like this protection of the User Name should apply to the Observation Name as well. The MO Observation Name should be allowed to be changed only by the original user who posted that observation. In a normal data processing databases, the original name of the item is protected and the changes are being proposed in the so-called Annotations. MO Comments could be used in the case of MO, when MO does not know what the annotations are. LEAVE THE MO NAME CHANGES ON THE ORIGINAL USER! Let the original user to eat the humble pie! MO as it is now, is an excellent example of what I would call a “citizen science”. It is brilliantly programmed in its databasing part, but its mycological databasing is an obvious failure. Never mind, both I and Oluna welcome any oportunity to enrich our English vocabulary, especially in its parts that are not commonly used among polite people.
One of the best sci-fi shows out there and smeg and all of its derivatives are pretty amusing words. :)
“Smeghead” should have a space between the two words.
For information on the etymology of this unusual term, see http://www.urbandictionary.com/define.php?term=smeg+head.
when the cf. is used and how.
In short, cf. means “Compare with”. It refers to where the identification seems right and there are not other described possibilities, but due to some details its not certain. In this case it would refer to the massive distribution jump for an underrepresented taxa.
Group refers to when we know there are several similar species that form a coherent group that are difficult or not currently possible to differentiate without microscopy, DNA or other. One example of this would be Pisolithus under pines or oak seem to form a coherent morphological and genetic group which we could call Pisolithus arrhizus or P. tinctorius group (I’m not sure which would be preferred?).
For this observation the choices are limited to:
1) This is Coprinopsis scobicola.
2) There are other undescribed and undiscovered Coprinopsis species with 2-spored basidia it could be. There is no evidence of this and I would hesitate to propose names accordingly until it is shown to be correct in which case “Group” would be appropriate.
3) My microscopy was flawed and this should be called Coprinopsis sect. Lanatuli, however I do not think this is right and Adolf only bumped this observation because he’s upset at being wrong and has inappropriately singled me out as the source of the issue.
However, I failed to preserve this collection, so its all kind of pointless until someone finds another collection of this and does save it. It could be common, but no one really seems to care about these and they are admittedly hard to work with and preserve.
I looked at the basidia carefully, they were two spored. At least the ones I have observed. Coprinopsis cf. scobicola might be a good name here since this clearly keys out and matches that that taxon. However MO does not yet support cf. names, I will suggest this feature now.
