Observation 22917: Spathularia Pers.

When: 2009-07-03

Collection location: Workman Track, Workman Rd., Hunua, Auckland, New Zealand [Click for map]

Who: Clive Shirley (myxo)

No specimen available

Notes:
Can any one suggest a genus for this fungi found in mixed leptospermum/Nothofagus bush in a large group of 500 plus fruiting body’s. The stand about 25 mm high and have typical ascospores long and narrow. These are definetly ascomycetes as asci can be seen.

Spathularia sp.

I have made a few local inquires and even though this species is known it not described. Which seams to be an ongoing problem as barely a week goes by without something turning that is undescribed.

Branched fruitbodies – and nice pictures of it too.. At least I do beleive it belongs in the Helotiales order… I hope that you’ll find a name on it, or that somebody creates a new species, named in your honor :-)

Thanks all who have made suggestions I have been checking them out but so far I have had no eureka moment! The spores are 5 × 1 um so I guess this counts out Spathularia and Cudonia. Most of the genus been suggested have not previously been found in New Zealand, I fear this is yet another undescribed species. Thanks all for your help so far, I have added a few more images the last was stained with Congo Red. Unfortunately the microscopic detail is so small its much beyond the resolving power of my microscope.

Not microscopic…

apothecia is just a descriptions of a flat surface of asci, this is compared to parathecia, where the asci are bunched and covered in “pimples”. These are kinda the two major splittings of the ascos. This isn’t a microscopic thing, you can see it. Compare to Cordyceps, or Daldinia, or Hypoxylon, where the spore bearing surface is covered in little pimples.

Yes, apothecia

- the sporeproducing part of the ascomycete – the part that bears asci, the ascocarp – the “head” on these clubshaped mushrooms. Is there a better name for them?

Apothecia?

I see nothing in the description about apothecia. Can you really see them in the photos, Irene? Do you have Dr. A.H. Smith’s trick microscopic eye?

The way the apothecia are attached to the stem – maybe not the way Spathularia is described? Cudonia are very close relatives, as well as the obscure genus Pachycudonia.
But I just remembered another possible genus with small fruitbodies: Heyderia.

Where’s Clive? More info from the microscope is needed!

Spathularia?

That would be my guess, but they are unlike material I have seen locally. Then again, I haven’t had to pleasure of looking for fungi in New Zealand. Pity.

Spore size?
By: Irene Andersson (irenea)

Very long spores, 30 microns or more, suggests Spathularia or Cudonia.
Shorter spores, around 10-15 microns could mean Mitrula or Bryoglossum, but I think the stems are too dark for Mitrula.

Many possibilities
