Microscopic features of Liebetanzomyces polymorphus showing pleomorphism in sporangial and rhizoidal structures, when grown on different carbon sources like rice straw (A), wheat straw (B), cellulose (C), xylan (D), starch (E), cellobiose (F), lactose (G), maltose (H), sucrose (I), glucose (J), xylose (K) and fructose (L). The exogenous sporangia appearing on a sporangiophore (A–B) and endogenous sporangia of different shapes (C–L) are shown. Scale bar: 20 µM.
