Observation 87798: Tubaria (W.G. Sm.) Gillet
When: 2012-02-14
Who: Byrain
No herbarium specimen

Notes: Scattered on a grassy hillside, I did not observe any moss.

The cheilocystidia and pleurocystidia are similar, clustered, strangulated, irregular, sometimes branching and/or with clamps. Some parts of the gill seem to be completely absent of them while others they are plentiful.
4-spored basidia are present and the pileus hyphae is smooth.

The spores are smooth without a germ pore and I measured 15
Spore range = 8 – 10 × 5 – 5.5 (6) μ
Average spore = 9.07 × 5.62 μ
Average Q = 1.77

Here is another micro description for T. furfuracea, “spores 6.5-9.3 × 4-5.5 um, elliptic to cylindric-elliptic, smooth, light yellow; pleurocystidia not seen, cheilocystidia 23-53 × 5-9 um, cylindric to somewhat lageniform or flexuous (curved both ways), occasionally subcapitate” http://www.svims.ca/council/Key_to.htm#nTcon

My sizes are not far off from that, though the cystidia still don’t seem to match at all. I think Tubaria sp. is a good name for now, thanks for the explanation. :)

has smooth, ellipsoid and thinwalled spores. That goes for a few Galerina too, but then they have different cystidia (tibiiform – with small round “heads” and a neck). I agree that the spore size is above the upper limit for furfuracea. Maybe “furfuracea group” or just Tubaria sp. is a better suggestion?

Why T. furfuracea?

T. furfuracea has a spore size reported at 6-8.5 × 4-6 µm and is said to have “Mainly cylindrical, occasionally subcapitate” cystidia. Here is a picture.

Why Tubaria and not Galerina? I guess I could use some tips on telling them apart.
