Anamorph on Buxus.
Josep Torres, 15-11-2025 09:21
Josep TorresHello.
An anamorph resembling Capronia is sprouting on the surface of decaying Buxus sempervirens leaves in the soil, sharing space with ascomata that are supposedly Ceuthospora buxi, although this is still unconfirmed. The ascomata are blackish, with a diameter of 100 to 280 microns (excluding the hairs). Some of the external hairs exceed 250 microns in length and are 6 to 8 microns wide at their base. These thick-walled, septate hairs contain intracellular pigment and end in rounded shapes.
The perithecium wall has a globose-angular texture and is heavily pigmented.
Conidiogenous hyphae are difficult to observe, but a vertical palisade arrangement is discernible. These hyphae produce fusiform conidia with a more pointed end, mostly with two septa and, exceptionally, some with three. These septa are more visible in Melzer's reagent and show no signs of constriction. Measurements of these conidia in water are:
(27.7) 28.9 - 35.6 (37) × (3) 3.1 - 3.9 (4.4) µm
Q = (7.6) 8 - 10.6 (11.4) ; N = 30
Me = 31.8 × 3.5 µm ; Qe = 9.2

I admit that I'm completely lost this time.
Any input would be greatly appreciated.
Thank you in advance.
Best regards.

Re : Anamorph on Buxus.
Thank you very much, Angel.
I haven't been able to find any information online about the Wojnowicia ephedrae you mentioned, and almost nothing about the genus Wojnowicia, which I was completely unfamiliar with.
I understand that Wojnowicia ephedrae would be associated with Ephedra sp., given its host (Buxus). I'm not sure if we should consider Wojnowicia buxi.
Any information you could provide about the genus would be greatly appreciated
Best regards.
