Small Scutellinia on wood
Malcolm Greaves, 23-07-2013 00:00
Malcolm  GreavesThis group of small Scutellinia (maxium size 2.5mm) with relatively long hairs (5oo x 20) with simple or bifurcate hairs had me convinced I had S setosa.
The spores turned out to be slightly too big at 21-22 x 13 and the ornamentation confirmed it definitely was not S setosa.
With large tubercules could this be S heterosculpturata?

Thanks

Re : Small Scutellinia on wood
Adio Mal,

Surely, you're right, it's not S. setosa. S. setosa is recognized easily at the naked eye by form of apothecia, colour yellow to yellowish, and very black hairs.

Second hypothesis, S. heterosculpturata doesn't correspond. This species is recognized by elongated spores (Q>1.7) and a mix of very little warts and some big in the middle.

Here, without spores, I will say a species of "S. nigrohirtula" complex. In fact, two species are in this complex, probably one on soil and one on wood but I haven't finished the study. Here, hairs are typical.

With spores, it's difficult to confirm this, but I repeat it's necessary to have sporogram with a lot of mature spores, naturally ejected, to be sure that sporal ornementation is homogeneous. Here, we have just one spore and it's difficult to say anything around this.

In this genus, it's very common to have different views of sporal ornementation between mature apothecium, immature, spores in asci or not, in sporogram or alone in the water.
That's why it's very necessary to have sporogram in CB.

Amically,
Beñat
