Fig. 49A–C

Acta Mycologica 34: 9 ( Majewski 1999). –

Type: “ Holotypus: Poloniae, Bialowieza , sectio silvae 255C, super Bryaxidis bulbiferis (Reichenbach), 23.7.1998, leg. T. Majewski ( KRAM, No TM 8665 )”; KRAM.

Diagnostic features

Appendage unbranched, consisting of several superposed, almost globose cells separated by constricted septa. Some of these cells in middle and upper region of appendage with antheridia as corner cells in both sides. Perithecial apex showing four small teeth below the conical tip ( Fig. 49C , arrows). [Detailed description: Santamaria 2003]

Distribution and hosts

Only known on Bryaxis bulbifer from the type in Poland, and from Spain on the same host genus ( Santamaria 2001a) and later on Bibloporus Thomson, 1859 ( Santamaria 2003) . Hosts belong to Col. Staphylinidae Pselaphinae .

Remarks

First record from Denmark. Before its description, C. bryaxidis was confused with Cryptandromyces elegans ( Majewski 1999) but this is much larger, brightly coloured and typically bears flask-shaped phialides on the inner lower side of the appendage.
