Specimen notes
Public Note:
FTA Card
Public Note:
30th Fungal Foray of New Zealand
Public Note:
Host is good for L. apalum, and morphology not bad, but this specimen has paraphyses sublanceolate at best , whereas L. apalum is supposed to have broad, lanceolate paraphyses. Based on ITS this specimens is phylogenetically close to Asperopilum juncicola. This specimen differs from PDD108742 because the apothecia are yellowish rather than white, the ascospores are perhaps a little shorter, and the ascus apex has a bowl-like shape to the apical thickening (compared with narrow pore extending upards in PDD 108742).

Public Note:
Two Lachnum spp. from Juncus having apothecia with a yellow hymenium and white or pale yellowish receptacle and hairs, have been sequenced. Phylogenetically they are quite distant within Lachnum, and the two species differ in ascospore size and also in the arrangement of the wall thickening at the ascus apex (see images attached to the specimens). PDD 108737 (D2396) has ascospores about 40 x 2 um and perhaps represents L. apalum sensu Spooner p. 661; PDD 108742 (D2397) has ascospores about 45-58(-65) x 2 um and morphologically seems closer to the Australian taxon L. apalum var. beatonii. In some cases the same Leotiomycetes species, with identical ITS sequences, occurs on the same substrate in both New Zealand and Australia, but often specimens from the two countries represent genetically slightly distinct sister species. There is no DNA sequence data available from a Lachnum apalum like specimen from Juncus from Australia so it is not possible to check in this case.
