Septonema sp.

Mitosporic fungus. Hyphomycetes.
Septonema species comprise a very small proportion of the fungal biota. This genus is somewhat related to Cladosporium. No information is available regarding health effects, or toxicity. Allergenicity has not been studied. May be identified on surfaces by tape lifts, and tease mounts from bulk samples. Septonema has somewhat distinctive spores which could be counted on spore trap samples if the presence of this genus has already been demonstrated (for example, on tape lifts). Commonly found on the bark of deciduous or coniferous trees as well as on other fungi, particularly the Pyrenomycetes. Less commonly found in soil and buried root pieces.
