Ceratosphaeria lampadophora vs. C. mycophila
Edvin Johannesen, 08-04-2025 17:31
Edvin JohannesenI have a fresh specimen of a Ceratosphaeria on dead wood (Populus tremula).  The spores measure (40-) 45 (-50) x 5 µm og asci (170-) 175 (-177) x 10-11 µm in water. I find conflicting measures for C. lampadophora in the literature. Does anyone have the correct measures for these two species? Are there other distinguishing characters that separate these two species?

I have photos if necessary.  Thanks!

Re : Ceratosphaeria lampadophora vs. C. mycophila
Hi Edvin,

C. lampadospora is a well known (holotype) and sequenced species, see Crous et al. (2020: 87).

Macroscopy: 
C. lampadospora has perithecia with a neck several times longer than its diameter, while in C. mycophila the neck is about half as long as the diameter.

Microscopy:
C. lampadospora has ascospores longer than 50 µm in average, while up to 50 µm long in C. mycophila. Septation similar (7-9-septa), although Saccardo (1883) and Berlese (1894) observed additional septa in C. lampadospora.

Habitat/substrate:
C. lampadospora occurs on rotten wood. Populus is a typical substrate. May be aquatic.
C. mycophila is fungicolous (always?)

Al the best,
Bernard

Re : Ceratosphaeria lampadophora vs. C. mycophila
Thank you, Bernard! The spores fit C. mycophila best and the ostiolar neck is also quite short.  It seems, however, that it is not associated with a fungus, at least not a fruiting body, but of course there is always mycelium of some sort in dead wood.

I can post some photos tomorrow.

Best regards,

Edvin

Here are some photos.  Can C. mycophila be confirmed?

C. mycophila maybe. Anyhow Ceratosphaeria lampadophora to be excluded.
