Rotiferophthora brevipes G.L. Barron 1991

ADDITIONAL RECORDS: From rotting debris of moss and liverworts collected at Marguerite Track, Waitakere Range, New Zealand, 26 December 1988; from organic debris collected on the grounds of DSIR, Auckland, New Zealand, March 1989.
The conidiophores in this species (Figs. 13, 16, 18) are 30-50 µm tall by 2.2-3.5 µm wide. Sometimes conidiophores consist of only a few short cells bearing a terminal phialide and one or two lateral phialides or aphanophialides. Occasionally a lateral branch is produced, but this also consists of a single, short cell bearing one terminal phialide. Phialides are 13.5-20 µm long by 3-4 µm wide with a swollen basal portion that tapers sharply into a short reflexed tip. The tip of the phialide frequently proliferates in age to form a polyphialide (Fig. 18). Phialides are mostly solitary, sometimes in pairs, and rarely in whorls. Aphanophialides tend to be short and stubby and are up to 7 µm long and 2.5 µm wide at the base; they taper sharply along their length to a narrow, often reflexed apex. Conidia (Figs. 15, 17) are 5.0-6.0 µm by 5.0-5.5 µm and broadly reniform in face view, with a large oil droplet disposed either centrally or slightly off centre towards the distal end of the conidium. In face view, the attachment end of the conidium can be recognized, as it is a little longer and slightly narrower than the distal end. Conidia in this species sometimes germinate in situ. An extremely narrow (less than 0.5 µm) germ tube originates from the middle of the convex surface. The germ tube is straight and simple at first but becomes undulating and sparingly branched as it elongates. Aleuriospores in this species are more or less globose in general outline and 15-20 µm by 17-24 µm, with an average of four per rotifer in good cultural conditions.
HABITAT: Parasitic in bdelloid rotifers.
Conidiophora perbrevia, usque ad 30-40(60) µm longa x 2.2-3.5(4.5) µm lata, simplica vel exigue ramosa; phialides 13.5-20 µm longae x 3-4 µm latae; aphanophialides plerumque usque ad 7 µm longae x 2.5 µm latae in pane basilare, attenuatae acute usque ad apicem angustam minorem quam 1 µm latam; phialoconidia 5.0-6.0(7.0) µm x 5.0-5.5 µm, concava alte in latere uno; aleuriosporae 15-25 µm x 15-24 µm.
TYPE: Slides in herbarium (OAC 10851), from soil collected on Kiko Road Trail, Kaimanana State Forest Park, New Zealand, November 1988.
