What are Lobulomycetalean Chytrids?
- The Lobulomycetales is a monophlytic order with one family and four genera.
- Two species formerly formerly classified in Chytriomyces (1) have been transferred to the recently established order (3).
- This is one of two orders of chytrids that includes dung inhibitors (the other order is the Spizellomycetales).
- Phylotypes which place in this clade are commonly found in molecular analyses of environmental samples, suggesting
a great deal of undescribed biodiversity in this order. It is of special interest that some of the sites of these phylotypes are harsh environments (3).
Current systematic synthesis of the order Lobulomycetales:
The Order Lobulomycetales includes four genera and five species:
Lobulomycetaceae D.R. Simmons
Alogomyces tanneri D.R. Simmons & P.M. Letcher
Lobulomyces angularis (Longcore) D.R. Simmons
Lobulomyces poculatus (Willoughby & Townley) D.R. Simmons
Clydaea vesicula D.R. Simmons
Maunachytrium keaense D.R. Simmons
Lobulomycetalean Chytrids are Found in Diverse Habitats:
Lobulomycetalean chytrids are common in the soil and have been found in horse dung.
