Monacrosporium subtile on unknown hyphomycete?
Jan-Arne Mentken, 14-03-2018 19:06
Jan-Arne MentkenHello everyone,

in recent days I found this anamorph which seems to be overgrown by another fungus. Only having Ellis & Ellis as useful literature I suggest that it could be Monacrosporium subtile. Ellis & Ellis: Microfungi on miscellaneous substrates, p. 35 say:

"Colonies thin, white, scarcely visible to the naked eye. Conidiophores erect, hyaline, straight or sligthly flexuous, 2-4 thick at base, 1-2 at apex. Conidia solitary, terminial, clavata to cylindric-fusoid, with 1 to 12 septa, hyaline, smooth, 40-72 x 5-7. On Cladosporium, Periconia, etc."

Even though this is probably neither Cladosporium nor Periconia. Could Monacrosporium subtile be an option? Does anyone possibly know this species or can identify the parasitized fungus?

Thank in advance for any idea!

Best regards,
Jan-Arne

The hyphomycete with synnemata and small shortly ellipsoid conidia is Phaeoisaria clavulata. Not sure about the other fungus, I'm afraid.

Hi Marcus,

I just had a quick look on what Ellis & Ellis write about that species and tried the key again. It worked, Phaeoisaria clavulata is certainly the correct name. Thank you so much!

Let's see if someone can find a name for the parasite.

Best regards,
Jan-Arne

Monacrosporium subtile is a dubious taxon fide Rubner 1996, possibly a Dactylella (Orbiliomycetes). In any case it has hyaline conidia.

Hi Zotto,

I somehow ignored that fact. So it can't be Monacrosporium subtile assuming one would even count it as a species.

Kind regards,
Jan-Arne
