Scutellinia crinita or pilatii ?
Sergey Markov, 10-07-2021 16:17
I found today some Scutellinia species on rotten trunk of Populus tremula. Diameter of apothecia up to 8-9mm. Length of hairs around 1.3 mm, hair roots multifurcate.

Measurements are placed on microphotos. More accurate measurements of spores on photo in congo red/SDS (40x lens), also multiple small oil drops is visible. Measurements of spores in CB (100x oil immersion lens) are no so accurate, but fine ridges and dots of the ornamentation is visible.

Is this S.crinita or S.pilatii? Spore measurements ((18.86) 19.47 - 22.17 (23.06) × (12.35) 12.68 - 14.18 (15.85) µm; Q = (1.30) 1.44 - 1.66 (1.76); N = 63; Me = 20.84 × 13.54 µm ; Qe = 1.54) are between these species according to Beñat Jeannerot's key (10.25664/ART-0287). According Schumacher's key S.crinita is more like, but also not exactly. Also swelling of the ends of the paraphyse seems strange to me for S.crinita.  Please help me.

WBR, Sergey Markov

Re : Scutellinia crinita or pilatii ?
I have studied two other apothecia from this collection (taken in close proximity to the previous) and they are almost typical S.crinita species (in exception of no big guttules in ascospores). All microfotos in pure water from fresh material.

I'm sorry for the trouble - previous apothecia was just atypical, but also must be S.crinita.

Re : Scutellinia crinita or pilatii ?
Hello.
In my opinion, your collection fits with S. pilatii, based on spore sze and ornamentation.

Re : Scutellinia crinita or pilatii ?
The first set of spores are not the shape I would expect for crinita and although I have no experience of pilati I would agree with Nicolas that it is likely to be that species.

Re : Scutellinia crinita or pilatii ?
Thank You very much Nicolas, Malcolm.

Here is now another problem - first spore set was taken from 1'st apothecia, and 2'nd spore set - from 2'nd and 3'rd apothecia as shown on the photo here. All three apothecia was mature and all (or almost all) ascospores was taken outside of asci. Yes, I understand perfectly well that the first set of spores doesn't look like S.crinita spores. But the 2'nd spore set ideally fits into S.crinita.

Can there be such as these two species growing so dense at the same time? I see such event is extremely unlikely, so I guess atypical ascomata of S.crinita.
