The lichens are attached to water-marked paper glued on to card, 11-12 x 7-8 cm and are<br />
named in ink by Acharius (Fig. 17). They are housed in packets mounted on herbarium sheets<br />
and enclosed in folders in the order stated in Acharius's catalogue. Tibell (1987: 258) has<br />
recently commented on the BM-ACH collection as follows '. . . specimens seem first to have<br />
been annotated according to Methodus Lichenum, and when the annotations were revised<br />
"mscr." (manuscript) and "Lichenogr. universal." were added. The "mscr." has been crossed<br />
out, possibly by Acharius himself after finishing the Methodus and Lichenographia universalis<br />
manuscripts. The drawback of the BM-ACH material is that no information on collectors or<br />
localities is supplied with the specimens. Its importance arises from the fact that this was<br />
probably part of the material Acharius was working with when he wrote the "Methodus" and<br />
"Lichenographia".' This view was stated by Swartz in letters to Turner (see p. 168 above) when<br />
he wrote that Acharius had spent a year preparing a named set of lichens '. . . which will be the<br />
truest and surest guide to his Methodus' (Swartz, 1806c).<br />
William Borrer (1781-1862) saw the Acharius lichens snortly after their arrival at the Linnean<br />
Society, examined them carefully and prepared manuscript comments on them dated 25 May<br />
1809 and 22 November 1811 (Fig. 18). These comments are maintained with the Acharius<br />
catalogue in BM-ACH.<br />
J. R. Laundon (BM) has prepared a detailed list of the BM-ACH collection including several<br />
additional taxa not included in the Acharius holograph catalogue. The full BM-ACH holding is<br />
shown in Table 1 .<br />
