Type: “ On Ptenidium turgidum Thomson. Bt. Bialowieza National Park , sect. 256, 18.6.1989 ( 4489 – holotype)”; KRAM. [ Poland]

Diagnostic features

Receptacle consisting of (4–)5–6 superposed cells (cell I included). Appendage ramified into several branches above 2 nd –5 th cell; some of the branches bear narrowly elongated, flask-shaped antheridia ( Fig. 13E–F View Fig , arrows). Cells of the base of the appendage typically inflated ( Fig. 13D View Fig , *). Perithecium appears to be terminal on the receptacle axis. Perithecial apex asymmetric, with a protruding lip. [Detailed description: Majewski 1994b]

Remarks

First record from Denmark and first since it was originally described. Unusual short thalli have been collected under the head of one host specimen, and we have decided to assign them to S. ramificans because of characters of the perithecial apex and the base of the appendage ( Fig. 13D View Fig ). A photo of this species is given here for the first time.
