Scutellinia cf. heterosphaera
Viktorie Halasu, 01-07-2016 02:17
Viktorie HalasuGood evening,
I would like to ask your opinion on this Scutellinia:

Found along forest road in a decidous forest, growing on bare soil, probably periodically humid place with some rests of wood/bark, ca. 350 m s.m. Fruitbodies about 3 mm diam.
Spores perfectly globose, (15) 16,5-19,5 (20,4) um (squash mount in LACB).
Ornamentation: mixed small and big tubercules, or both rounded and conical warts, (0,3) 0,4-1,5 (1,9) um high, rarely confluent but sometimes interconnected with fine lines.
Marginal hairs: often sinuous, with simple or shortly bi-(tri-)furcate base, both obtuse and pointed ends, 294-420 (606) × 17,5-23 um.
Lateral hairs with simple or shortly bifurcate base, shorter, often bent/crooked.


Could it be S. heterosphaera nom.prov. or did I overlook some other similar species? And are there any other significant differences between S. heterosphaera and S. minor, except for the ornamentation?
Thank you very much.
Viktorie

Viktorie
This fits perfectly with the description I have for S heterosphaera and the specimens I have found some of which were id'd by Beñat. Although you are right about the differences between the two species sporal ornamentation the spores of S minor tend to be subglobose when immature so check those still in the ascii

Re : Scutellinia cf. heterosphaera
Great, thank you very much, I'll check the immature spores during the weekend. Locality is in Moravia (eastern Czech Rep.). I wonder if they checked specimens from PRM or BRNM determined as S. minor or S. barlae, perhaps there might be some older collection of this species too.

Re : Scutellinia cf. heterosphaera
Immature spores are globose too, so heterosphaera it is. Thank you again.
