Effusum subcrustaceum, dense velutinum, intenseviridi-olivaceum; hyphae steriles repentes dense intricatae ramoso-intertextae olivaceae; hyphae fertiles numerosae erectae simplices breviusculae pluriseptatae virescentes, articulis superis sensim abbreviatis, conidiis secedentibus irregulariter vestitis; conidia typice ellipsoidea continua chlorina laevia parvula aliis polymorphis plus minusve numerosis concomitata.
In additional notes, Spegazzini (1923a) described unbranched conidiophores, 50-150 ´ 4-5 µm, with 5-10 septa and ellipsoid conidia, 4-10 ´ 3.5-6 µm. There is an original drawing made by Spegazzini on the envelope of the type collection, showing pleurogenous conidial formation which is atypical for true Cladosporium species.
