Type:
Macromitrium grossirete Müll.Hal.
I concur that this material (both mounted on the sheet and in packet) is what has been considered Macromitrium grossirete and that it seems to match Müller's description. The upper laminal cell papillae (both on abaxial and adaxial surfaces) are high (c. 15 µm) and either simple and rounded or irregular or weakly branched at their apices.
There is some variation in leaf form and degree of crisping when dry among the material in the packet, but all such material has very high laminal papillar and the relatively few intact capsules are representative of what has been called Macromitrium grossirete.
I accept Vitt's lectotypification.

Macromitrium grossirete C. Müll., Hedwigia 37: 153. 1898.
Type: "Nova Seelandia, insula sept., N. Canterbury, Pattersons Creek, Weimacariri Gorge, ad truncos arborum: T.W. Naylor Beckett 1892 leg. et misit."
(Lectotype - CHR - Beck)
Note: Lectotype chosen is No 395, April, 1892 as it matches C. Müller's description fertile material in packet, not No. 295, April 1892 "Names by Dr Karl Müller in litt 11 Dec. 1892" - This latter specimen is typical M. ligulare Mitt. and does not match Müller's description. The two specimens, both from the same locality were confused; Müller was obviously describing No 395 - grossirete, not ligulare.
