The cap has an interesting crunchy texture.
Growing on well decayed wood.
Spores smooth, inequilateral, 10.5 – 13 × 5 – 6.5 µm, with 1 or 2 oil droplets per spore. 8 spores per ascus. Asci walls invisible in KOH.
Spore measurements:
10.6 [11.4 ; 12] 12.8 × 4.8 [5.5 ; 6] 6.6 µm
Q = 1.7 [2 ; 2.2] 2.4 ; N = 15 ; C = 95%
Me = 11.7 × 5.7 µm ; Qe = 2.1

Keys out to Rhytidhysteron guaraniticum on two separate keys, can't find much information on the species apart from that however. At the very least exists in Paraguay.
On Citrus bark.
Mature ascocarps often exceed 2 mm in length. Width is variable with opening/closing, but closes to 0.4-1 mm.
Ascospores
23.3–33.5 × (8.4–)10.7–13.8 μm; Q: 1.94–2.92(–3.67)
Mostly 3-septate, often 1-septate, very rarely 2-septate.
Image Notes
All microscopy with 10 μm scale bars, mounted in KOH or LPCB
