TLDR
Data indicate that P. graminicola acts as a beneficial associate of V. ciliata ssp.Abstract:
Seedlings of the annual grass Vulpia ciliata ssp. ambigua were grown in sterilized sand with a dark septate root fungus, Phialophora graminicola, which had been isolated from a natural population of the grass. Tiller number and shoot, root and total biomass of seedlings grown with P. graminicola were enhanced relative to uninoculated control plants in a growth room and a glasshouse experiment. Root length of seedlings grown with P. graminicola was significantly increased, but no effects of the fungus on root diameter, number of root hairs or specific root length were recorded. Root nitrogen content and shoot, root and total phosphorus contents of seedlings grown with the fungus were enhanced, but shoot nitrogen concentration of these plants was reduced. Shoot biomass and specific root length of inoculated plants were positively associated with the number of P. graminicola colonies re-isolated from roots. These data indicate that P. graminicola acts as a beneficial associate of V. ciliata ssp. ambigua seedlings under controlled conditions.read more

TL;DR: The most likely functions of this poorly understood group of root-associated fungi are reviewed and it is proposed that, like mycorrhizal symbioses, DSE-plant Symbioses should be considered multifunctional and not limited to nutrient acquisition and resultant positive host growth responses.

TL;DR: It is suggested that DSE enhance plant performance under controlled conditions, particularly when all, or the majority, of N is available in organic form.

Microfungal endophytes in roots
TL;DR: A dichotomous key and annotated descriptions for a cross-section of the most common dark septate endophytes are provided, sometimes used to imply taxonomic and physiological similarity even though a diverse range of root endophytic taxa form pigmented hyphae.

TL;DR: In this article, an approximate procedure based on classical analysis of variance is presented, including an adjustment to the degrees of freedom resulting in conservative F tests, which can be applied to the case where the variance covariance matrices differ from group to group.

A new method which gives an objective measure of colonization of roots by vesicular—arbuscular mycorrhizal fungi
TL;DR: A modified method is described here to estimate VA mycorrhizal colonization on an objective scale of measurement, involving inspection of intersections between the microscope eyepiece crosshair and roots at magnification × 200; it is referred to as the magnified intersections method.
