Frantisekia is a genus of the stem porling relatives (Polyporaceae). It was first described in 2007; It bears its name in honor of the Czech mycologist František Kotlaba .
Frantisekia comprises a total of three types of fungi, which were previously assigned to the pore sponges ( Poria ), Antrodiella and the white sponges ( Tyromyces ) andliveas saprophytes . The type species after which the genus was described is Frantisekia fissiliformis (formerly Poria fissiliformis ).
features
Fruiting bodies
Once a year, the mushrooms of the genus develop fruiting bodies that are white or ocher in color and have a fleshy consistency. When dry, they discolor and become brittle. The fruit bodies are hat-shaped, broad and bent back or up. The fruit layer is spongy; the tubes run down strongly and have small pores (6 to 10 per millimeter).
Microscopic features
The mushroom meat of frantisekia TYPES is pseudodimitisch , that is, it consists of generative hyphae which serve the reproduction of the flesh, and Pseudoskeletthyphen that give the fruit body strength.
The generative hyphae have buckles and their walls are thin to slightly thick. They appear hyaline or slightly yellowish under the microscope . In the trama or in the tubes there are flattened pseudoskeletal hyphae, which, unlike real skeletal hyphae, have few buckles and thick septa and thus represent generative hyphae; they are also slightly cyanophilic .
The fungi do not have cystidia , but sometimes have pseudocystidic structures, so-called cystidiols. The basidia are slender and club-shaped, have four spurs and have buckles. The elongated-ellipsoidal to cylindrical basidiospores react neither with Melzer's reagent nor with cotton blue .
Damage
On hardwood fungi of the genus called white rot out. The wood becomes fibrous and foxing and it bleaches a lot. Dark lines run around the infested areas, separating them from the rest of the wood. In the final stage of the infestation, the wood dissolves more and more and takes on a spongy consistency.
Ecology and diffusion
Frantisekia attacks dead wood and feeds on the lignin content of the wood. The three known types are holarctic ( F. fissiliformis ,) westpaläarktisch ( F. fissliformis and F. mentschulensis , ostpaläarktisch) ( F. ussurii widespread).
Systematics
External system
The external systematics of Frantisekia is currently unclear. Spirin and Zmitrovich see in certain morphological structures such as the fleshy fruiting bodies, the grown tubes or thin-walled hyphae an indication of a close relationship to the genus Ceriporiopsis . However, since the latter is very heterogeneous and possibly contains several genera, this relationship is also not clear.
Internal system
According to Spirin and Smitrowitsch, Frantisekia comprises three types:
- Frantisekia fissiliformis ( syn.Antrodiella fissiliformis )
- Frantisekia mentschulensis ( syn.Tyromyces aurantiacus )
- Frantisekia ussurii ( syn.Poria ussurii )
etymology
The genus was named by Ivan Smitrowitsch and Vyacheslav Spirin after František Kotlaba on the occasion of his 80th birthday in 2007. The first description was published in an edition of Česká Mykologie dedicated to Kotlaba .
