Description: Conidia (isthmospores) complex, lobed, sarciniform, echinulate, and ca. 23 × 18 μm excluding the 1–2 μm long spines.

(Sub-) Fossil occurence: In Lake Challa sediments the spores of I. spinosa are rare, the few specimens being found mostly in Late-Glacial and Holocene sediments.

Co-occurence: No information

Modern occurence: In the tropics, Isthmospora spinosa is a hyperparasite on various genera and species of the fungal family Meliolaceae (Hughes, 1953; Ellis, 1971). It is known from Central and South America including the Caribbean, tropical Africa and tropical East Asia, and can be locally abundant. Ist teleomorph, Trichothyrium asterophorum (Berk. and Br.) Höhn., is rarely found but equally restricted to the same host and distribution range. Outside the tropics fossil conidia of I. spinosa, together with remains of its host ascomycete Meliola ellisii, which itself parasitized the heath plant Calluna vulgaris, have been recorded and illustrated by van Geel et al. (2006) in a Holocene raised bog. deposit from northern England.
