Byssonectria terrestris

Byssonectria terrestris

Byssonectria terrestris is a species of fungi in the Pyronemataceae family.

Similar to Byssonectria fusispora, but with colonies that tend to be more aggregated, sometimes with a well-developed pale subiculum. Ascomata are often slightly paler, paraphyses have curved rather than straight tips and ascospores are slightly smaller and not or hardly apiculate. Ascospores measure 20.5-23 (mean 21.8) x 8.4-9.1 (mean 8.8) µm in water, 18.2-20.7 (mean 19.6) x 6.4-7.5 (mean 7.1) µm in lactic acid.

Often found with Nannfeldtiella aggregata, another fungi in the family Pyronemataceae.
