Notes.

Species observed attached to the hindgut lining of Protonemura montana , measuring 280-340 × 40-60 µm in our collections. This species was described from France, associated with Nemoura variegata nymphs, in the stonefly family Nemouridae . The species has three different thallial morphologies ( Léger and Duboscq 1929b, Duboscq et al. 1948). Subsequent to the revision of the species by Duboscq et al. (1948), this endobiont was not reported again, until now, probably because of the thallus variability and, thus, relatively difficult identification. We only saw one of the thallial morphologies described for the species, this being the stouter and shorter thallus type. The other two morphological types show longer and incurved thalli, one type being wider than the other ( Duboscq et al. 1948). Neither was observed in our collections.
