Conidiophores scattered or crowded, solitary or in groups of 2 to 4, arising from a small pseudostroma of hyaline hyphal cells; they are straight or slightly bent. simple, smooth, 160-375um long, usually 2-4-septate, rarely 5- or 6-septate, with a thick (up to 3.3um) peripheral wall, 12-16um wide just above a barely swollen base, tapering gradually to 5.4-7.21um wide just below the apex which is swollen abruptly to 7.2-12.6um. The conidiophores are hyaline throughout most of their length but toward the apex they may be pale to dark olivaceous or the tipper cell may be olivaceous. Phialides are formed in a fasciculate group to 4 to 6 on the apical swelling of the conidiophore; the terminal phialide is surrounded by a whorl of 3 to 5 others. They are broadly ellipsoidal or obovoid, subhyaline to pale olivaceous, smooth, 12.5-18.0um long, 8.0-10.8um wide. Each phialide bears a single apical collarette which is up to 2um long and up to 3.5um wide; toward their base collarettes often become more deeply pigmented than the phialide cell. Phialoconidia 1-celled, spherical, thick-walled (up to 2mm), olivaceous, bearing conspicuous, dark olivaceous to black warts which are up to 1.8um wide and 1mm high; they measure (16-)23-29(-32)um in diameter and gather in a slimy head around the apex of the phialides.
