Hyalorbilia on Tilia
Zuzana Sochorová (Egertová), 26-07-2021 22:17
Zuzana Sochorová (Egertová)Hello, 
this Hyalorbilia is from the Czech Republic, collected on a wet decaying twig of Tilis (ca 8 cm thick), in a castle park, 400 m a.s.l.

Asci 18 - 25 × 3.2 - 4.1 µm, 8-spored, base unstalked, unbranched.
Pars sporifera 8.3-10.6 µm.
Ascospores (4.2) 4.9 - 5.7 (5.8) × (0.7) 0.8 - 1 (1.1) µm, straight, with 1 SB near each pole.
Q = 4.4-7.6, Me = 5.2 × 0.9 µm; Qe = 6
Conidia 22 - 27 × 4.9-5.1 µm, unbranched, septate.

Using the key to Hyalorbilia in the monograph, I am coming somewhere around H. japonica (distribution not fitting), H. oreadum and H. herbicola (substrate not fitting + a bit deviating width of spores). So, could this be H. oreadum?
Thanks, Zuzana

Re : Hyalorbilia on Tilia
My first idea would have been H. inflatula with wide marginal cells. But spores are a bit short. H. oreadum is not very clear because of too few collections.

H. inflatula is not clear as to how many species are hidden behind it.

When you go to Plate 77 fig. 9 you can see a spore size just as in yours.

Re : Hyalorbilia on Tilia
Thanks a lot, Zotto. Yes, the elements are a bit shorter than should be typical for inflatula.
