Can someone help me!
On April 18, 2025 I found a pyrenomycete in asexual state on an old seed-pod of Cytisus scoparius.
The conidiomata were located in a tear of the epidermis of the seed-pod. Under the microscope I only saw the peridium and a lot of conidia. Conidiophores or conidiogenous cells were not noticed.
a) The pycnidia are spherical with an average diameter of 325 µm;
b) The conidia are light olive-brown, somewhat irregularly elliptical / fusiform, occasionally bent with one septum in the middle or slightly below the center.
Dimensions: (8.5) 9.1 - 11.9 (12.2) × (2.6) 2.7 - 3.3 (3.5) µm
Q = (2.8) 3.2 - 4.2 (4.3); N = 25
Me = 10.6 × 2.9 µm; Qe = 3.7

Any help is welcome, thanks in advance,

François Bartholomeeusen

N.B.: I will register a new entry on the forum of a second anamorph on a seed-pod

Hi François,

Just a guess: alpha-conidia of some Diaporthe (anamorph = Phomopsis).
