Conidiomata on Picea cone

Alain GARDIENNET

Bonjour à tous,


Found on Picea cone, pycnidia containing dictyosporous conidia.


Here are pictures.


Conidiophores up to 30 x 5 µm, conidia globulose to pyriform, up to 40 µm long when pyriform, and 30 µm diameter when globulose.


Any idea ?


Alain

Re : Conidiomata on Picea cone
Hi Alain,

Looking at "The Genera of Hyphomycetes - CBS Biodiversity Series 9" it resembles Pseudocanalisporium (although CDM not in agreement, this is my best guess), or perhaps Berkleasmium (CPH and CGC not in agreement), but I'm not sure, at least you can use as a start point.
I'm attaching the original description of Pseudocanalisporium by Castañeda & Kendrick.
Good luck.
