Brown Hyphomycete
Peter Thompson, 07-11-2018 11:47
Hello Everyone,

I have found a colony of brown hyphomycetes growing on a dead branch of Corylus avellana.

They have mid- to dark brown, regularly septate conidiophores, about 8 um wide, with short branches below the tip.

The mature conidia are brown, mostly 4-septate, hardly constricted at the septa, with a scar 4 um wide at the base. They typically measure 57.5 - 60 x 13 - 14 um. Immature conidia appear to have bluish tints.

It seems that Martin Ellis did not encounter this species, as there is no description / illustration in his books.

I attach a photo and wonder if anyone has an idea as to what they might be.

Thank You,
Peter Thompson.

Re : Brown Hyphomycete
Hello Peter

This hyphomycetes seems with some species of Dendryphiopsis.

Re : Brown Hyphomycete
Hello Josiane Monteiro,

Thank you for your help with the likely genus for my hyphomycete sample.

I will look more deeply into the species. Some like Dendryphiopsis biseptata can be quickly eliminated.

Interestingly, images of Dendryphiopsis atra are showing the same bluish tints in their young conidia.

With Best Wishes,
Peter.
