Pleurophragmium peruamazonicum Matsush. , Matsushima Mycol. Mem. 7: 61. 1993.

Typus.

PERU • Loreto, forest Rio Negro ; on decaying palm leaves; Jun 1992; T. Matsushima ( holotype MFC-2 P 079 ) .

Notes.

The species is characterised by versicolorous, 3 - celled conidia with a brown median cell and hyaline end cells. Its conidiophores bear an apical fertile region that often extends along the upper half of the conidiophore axis, with denticles sparsely distributed ( Matsushima 1993). Morphologically, it is strikingly similar to P. tricolor (nom. inval., Art. 40.1; Rambelli 2009); for a detailed comparison, see Table 3 . While P. peruamazonensis was described from culture, measurements of P. tricolor were derived from natural material. Consequently, features that distinguish the two taxa, such as conidial size and the extent of the apical fertile region, may simply reflect differences between in vitro and in vivo observations.
