Re:Psilachnum cassandrae
Super!

The morphology of the stipe cells and spore-shape shift this species clearly to the genus Antinoa (comp. Antinoa juniperinella). Sudently I does never seen the living features, for example contetnt of the paraphyses, and/or I have never seen the anamorph (it is intresting if is also the Chalara?).
Did you seen any mitosporic fungi assoc. with the teleomorph in-situ ?

regards

Re:Psilachnum cassandrae
Paraphyses as well as marginal hairs contain large colorless VB of elongate-type filling almost all cell volume. Small more or less globose VB also present in hyphae of the stipe cortex. Spores without lipid bodies or with very small subpolar LB-like granulae.

Best regards,
Eugene
