Duportella is a genus of fungi within the family of the cystid bark fungus relatives (Peniophoraceae). The genus is very similar to the closely related cystid bark fungi ( Peniophora ) and is characterized by its brown, encrusted pseudocystids and by its skeletal hyphae . The type species of the genus is Duportella velutina Pat. The white rot fungi are predominantly found in the tropics, but the genus is not represented in Europe.
features
The resupinate to effuso-reflex fruit bodies have grown on the substrate. The hymenium is smooth and greyish, reddish, purple, ocher or blackish in color. The hyphae system can be monomitic or dimitic . Most hyphae wear buckles . There are also two different types of cystids . Namely the pseudocystids , which are brown in color and encrusted with crystals at their tips, as well as the gloeocystids , which are mostly sulfoaldehyde-positive. The cylindrical to narrow-lobed basidia have four sterigms and a basal buckle. The smooth, inamyloid and thin-walled basidiospores can be shaped very differently. Their shape is an important feature for species delimitation. They can be ellipsoidal to ovoid, spherical or cylindrical to allantoid (sausage-shaped).
Ecology and diffusion
The representatives of the genus are saprobiontic white rot fungi that grow partly on dead hardwood, partly on dead branches that are still on the tree. The genus seems to be distributed exclusively in the tropics. The most widespread are Duportella tristicula and Duportella kuehneri , which are distributed over almost the entire tropics. Duportella velutina and Duportella raimundoi have been detected in the Philippines, Duportella pirispora , Duportella renispora and Duportella rhoica in Africa and Duportella kuehneroides and Duportella miranda on the islands of Réunion and Taiwan . Duportella tristiculoides occurs only in Taiwan, Duportella jordaoensis only in Brazil and Duportella sphaerospora only in New Zealand.
Systematics
The genus was re-described in 1915 by the French mycologist Narcisse Théophile Patouillard . The type species Duportella velutina and Duportella raimundoi were collected in the Philippines. The genus is characterized by its brown, encrusted pseudocystidia and skeletal hyphae. Duportella is closely related to Peniophora , as ITS-RNA studies by J. Boidin and his co-authors have shown. In its family tree, Duportella tristicula and other Duportella species formed a community of descent with Peniophora . In 2007 KH Larsson consequently placed them in the family of cystid bark relatives. Binder and his co-authors see it more in the corticoid branch of the Homobasidiomycete family tree.
The genus name is dedicated to L. Dupor, an avid collector and naturalist who collected the first specimens of these mushrooms.
species
There are 13 species worldwide, the genus is not represented in Europe.
