Rhodotarzetta's anamorph ?
Nina Filippova, 01-03-2015 13:22
Dear forum,

I have something Botrytis- like that may by an anamorph of Rhodotarzetta rosea in culture but i am not sure. I have inoculated dried pieces of apothecia and there were similar looking colonia in all Petri dishes. I am only learning in cultivation technique (it is still winter, therefore i use dried material) and thefore could have mistakes. Please, if you have some suggestion about this anamorphic species, it would be wonderful to know.

Potato-glucose-yeast-agar-charcoal (PH7): Colonia fast growing (9 cm in 3 days), grayish, with brownish conidial mass, pubescent, floccose and forming small sclerotia-like blobs, with not distinct radial zonation.

Yeast-agar-charcoal (PH7): Similar characteristics, but colonia much thinner, slowly growing and conidia barely forming.

Conidiophores about 5 broad, dichotomously branched, terminal fertile cells inflated up to 12 in diameter, producing conidia on short stalks; conidia ellipsoid, with short stalk, pale colored, light brownish in mass by naked eye, *13.7 (9,8-16.2) [17.7] x 6.7 (6-7.7), n=15.
The inoculation of a swan (sand-bran-charcoal) produced extensive growth, all volume was colonized in a week; no apothecia formed so far.

Re : Rhodotarzetta's anamorph ?
Did you compare Oedocephalum? I am not familiar here but this would be my first idea.
