Mariannaea elegans G. Arnaud 1952

Collections Examined

On dead wood, ( 1 ) Podocarpus spicatus Canterbury Prov., Kaituna Valley, Banks Peninsula, 15.X.1963, DAOM 1 09381; (2,3) unidentified hosts, Auckland Prov., (2) Heriderson Valley, Waitakere Range, 27.XII.1962, J.M.D.. PDD 20370 (DAOM 93829): (3) Kirk's Bush. Papakura, 15.1.1963, DA0M93830.

Description

Conidia are continuous, ellipsoidal to angularly fusoid, 4-6 X 2.3-3.0µm. I described (Hughes 1951c) a diffusely branched form of fructification as well as the simple type; both kinds are present on PDD 20370. Samson (op. cit.) validated the generic name Mariannaea Arnaud for what has commonly been called Paecilomyces (Corda) Mason et Hughes, because the phialides are more slender than in Paecilomyces Bainier and the conidia produced in slimy beads or in obliquely imbricate chains.
