SPECIES, AUTHORITY A. succineum Caspary 1907, p. 10, pl. 1, fig. 5.
LOCATION Baltic area, Poland.
ORIG DESCRIPTION* On the leaves and stems of Widdringtonites oblongifolius G. var. longifolius Caspary (illustrated l.c., on pl. 9-10, as figs. 45-55) are a few spots that are covered by a dark-brown fungal mycelium, the hyphae of which are about 4.2 µm or a bit more in thickness and adhere closely to the surface. From these arise short, perpendicular threads that terminate in an obovate or subspherical head. In several places similar threads break directly through the epidermal surface of the leaf, where no mycelium can be seen on the surface of the infected organ. In these specimens, the mycelium must be present within the leaf or its stem. The spore-bearing, upright threads are often slightly transparent in their upper part, about 4.2 µm thick and 85-96 µm long. The head is 22.7 µm long and 17 µm thick, often transparent in its basal part. No septa can be observed in the opaque upper part.
COMMENTS* This form belongs in the genus Acremonium Link. It closely resembles A. fuscum Schmidt, which is olive-brown.
