Hyphomycete on Pyrenomycete

Hi All,


Recently I collected what I thought to be a setose pyrenomycete on a broad leaved twig in fenland. It turned that the 'setae' were, in fact, a hyphomycete growing on old pyreno ascomata. The conidiophores were up to about 250 long and the conidia 20-23x11-14. The conidia were initially hyaline and thin-walled but became thick-walled and olivaceous brown on maturity. The detached conidia were 3-septate. I think it is an Endophragmia but I can't be sure which one.

Hi Charles

I think it's Endophragmiella boothii.

Re : Hyphomycete on Pyrenomycete

Hi Marcus,


Many thanks for that. Does it often grow on other fungi or is it normally found on dead wood?


Best wishes,


Charles.

Re : Hyphomycete on Pyrenomycete
Marcus is spot on. I think it's plurivorous, although interestingly I have encountered it on at least three collections of Orbilia rubrovacuolata and there is a conidium in one of Zotto's images of that species - see http://www.ascofrance.com/search_forum/32177 (two separate examples of this; the association must be accidental / similar microhabitat requirements).

The illustration in Ellis and Ellis I is a little misleading, it's taken from a larger set of images in Dematiaceous Hyphomycetes by Martin Ellis which shows those and more typical conidia.

Re : Hyphomycete on Pyrenomycete

Hi Chris & Marcus,


Yes, I did go through all the Endophragmias in Land Plants but none seemed to fit satisfactorily so I wasn't sure. Is Dematiaceous Hyphomycetes a better text for these fungi? Anyway, quite a distinctive species-do you come across it often?


Best wishes


Charles.

Re : Hyphomycete on Pyrenomycete
In my experience it's one of the commoner dark hyphomycetes on decaying branches and twigs. As Chris says, it grows on a range of tree and shrub species.

The 2 volumes of Dematiaceous Hyphomycetes generally have fuller descriptions and more illustrations than Microfungi on Land Plants. It's also often useful to have species arranged by genus rather than by host, as you can compare related species more easily.

Re : Hyphomycete on Pyrenomycete

Hi both,


Many thanks for your help.


Just had a look at FRDBI and it does appear to be reasonably common but I didn't see any previous Welsh records Lots of Marcus Yeo records! Might try to get hold of those volumes.
