Specimen from Skimmel Bridge
(DTH) may link var. curnovii and var. squamosa since it has
the large spores of the former but a small apiculus on some
perichaetial bracts as in the latter. The few records
identified to vars. do not suggest any difference between
their habitats (see above).
Recorded c.fr.: capsules immature: 7.
