This specimen has no collection data associated with it. The reference number 6 is writtenon the packet, but other packets with a 6 do not match this specimen.
The packet contained two envelopes, one labelled "Pyrenula nitida (Schrad.) Ach." and the other "Pyrenula nitida Major".
The handwriting of the names on the envelopes is often associated with H.H. Allan's specimens from the 1930s that were duplicates of specimens sent to A. Zahlbruckner in Vienna.
