hyphomycete a abies

DirkWsalut a tous,

does anybody know this imperfect fungus on cones of abies? i had expected phragmotrichum chailletii (which is on picea-cones), with this beautiful spores. but instead of i found very ordinary fusoid spores with 11-14 x 2, nothing more.

best to all

High Dirk

were the spores 1-septate? I remember that Bernd Mühler from Chemnitz sent me something with such fusoid eguttulate conidia, I think with 1 septum, but I did not documentate and finally threw it away.

It was on a conifer cone, maybe Abies. Your images are too unsharp to see details.

hi zotto,

yes exactly! one middle-septum ...
sorry for the bad mikro, my foto-equipement in this case is very simple ;-)

Re:hyphomycete a abies
Hi Dirk,

This could be Sirococcus conigenus. Normally, I find it on Picea cones, but there is evidence in literature, that it also comes on Abies alba (literature cited in a paper by Rossman et al., Forest Pathology 2007 , http://ddr.nal.usda.gov/bitstream/10113/12221/1/IND44005645.pdf).

Regards hermine

Dear Hermine

I tried to open this document, but I did not arrive. Do you have a scan of that literature about Sirococcus?

I easily found this on a site about Picea disease.

Re:hyphomycete a abies
it is available online: http://ddr.nal.usda.gov/bitstream/10113/12221/1/IND44005645.pdf

I also agree that this looks very much like Sirococcus conigenus on Picea cones.

Best wishes,

Gernot

Re:hyphomycete a abies
salut et merci a tous!

especially gernot for the instructive article!! i will follow this track further!
what is irritating me a bit is the irregular and caved surface of the stroma in the plant dease-painting. my stromas are quit plain and globose ... but it seems to be this taxa, the spores fit perfect. or something very close, which is concerned with abies ... i will have an eye on it ...

best to all and much fun in melle!
