Liverworts, Mosses, Lichens, Fungi & Seaweed

 

The lower plants and fungi have been well studied on Dawlish Warren over the years, this page only gives an example of species recorded, more detailed lists are yet to be uploaded to the site. We hope to be able to publish these pages in the near future, but if you have any records you can add to this database please send them on.  All information will of course be forwarded to the reserve wardens.

A 1997 visit by David Holyoak and other members of the BBS discovered the presence of the internationally rare species Petalwort Petalophylum ralfsii growing on the reserve. This species is found on dune systems and its occurrence, along with the wealth of other rare species present was a major factor in the awarding of Special Area of Conservation status to the reserve. The same visit also found Weedy Frillwort Fossombronia incurva, which was a first for Devon!

 

At least 37 species of Mosses and Liverworts had been recorded on site prior to 2000, including the nationally rare Rabbit Moss Cheilothela chloropus. Since then work by Frank Bryan has recorded the following species.

 

Bryum algovicum (Drooping Thread-moss): pioneer species found on seaward dune ridge


Brachythecium albicans (Whitish Feather-moss): widely distributed on dune ridge and on drier areas of dune grassland


Bryum capillare (Capillary Thread-moss): widespread throughout site


Tortula ruraliformis (Screw-moss): pioneer species widely distributed on mobile dune and stable dune grassland


Ceratodon purpureus (Redshank): found on bare acid soil in Greenland Lake


Brachythecium rutabulum (Rough-stalked Feather-moss): damp woodland on decaying logs, leaf litter and base of trees.


Brachythecium mildeanum (Sand Feather-moss): only found in one location on dune ridge.


Dicranum scoparium (Broom Fork-moss): common throughout dune grassland


Polytrichum juniperinum (Juniper Haircap): characteristic of more fixed dune grassland


Campylium polygannum (Starry Feather-moss): found in small fenced off area of Dune Slack close to visitor centre


Campylopus introflexus (Heath Star Moss): found at several locations on dune grassland.


Eurhynchium praelongum (Striated (Common) Feather-moss): common in shady areas and damp woodland.


Pseudoscleropodium purum (Neat Feather-moss): common grassland species.


Rhytidiadelphus squarrosus (Springy Turf-moss): common grassland species.


Calliergonella cuspidata (Pointed Spear-moss): common species of wet grassland and dune slacks.


Fissidens adianthoides (Maidenhair Pocket-moss): found at one locality in a wet hollow on the edge of Greenland Lake.


Bryum pseudotriquetrum (Marsh Bryum): common in dune slack.


Barbula convoluta (Lesser Bird's-claw Beard-moss): common species of shallow and stony ground.


Metzagaria furcata (Forked Veilwort): epiphyte; dark green liverwort found on trunk and branches on willow


Frullania tamarisci (Tamarisk Scalewort): epiphyte; purple liverwort found on trunk and branches of willows.


Brachythecium rivulare (River Feather-moss): found in damp woodland.


Cryphaea heteromalla (Lateral Cryphaea): characteristic epiphyte of elders, apple and other trees and associated with O.affine and Z. viridissimus.


Orthotrichum affine (Wood Bristle-moss): dark green epiphyte found on on tree branches and trunks.


Rhynchostegium confertum (Clustered Feather-moss): irregularly branched and silky moss found at base of several tree species.


Isothecium mysorouides (Slender Mouse-tail Moss): base of mature willow.


Ulota crispa (Crisped Pincushion): dark green epiphyte on tree branches and trunks.


Ulota pylantha (Frizzled Pincushion): epiphyte found on several trees.


Orthotrichum diaphanum (White-tipped Bristle-moss): epiphyte characterised by thick hyaline point; found on mature elders.


Tortula laevipila
(Awl-leaved Screw-moss): characteristic epiphyte of elders, apple and other trees and associated with O.affine and Z. viridissimus.


Zygodon viridissimus (Green Yoke-moss): distinctive diminutive lemony-green epiphyte found on elder.


H.cupresiforme var respunatum (Supine Plait-moss): found at the base of trees.


Hypnum cupressiforme var. filiforme (Plait-moss): found on trunks and branches of many trees.


Hypnum cupressiforme var tectorum (Cypress-leaved Plait-moss): common grassland species.


Hypnum cupressiforme var ericetorum (Plait-moss): common grassland species.


Funaria hygrometrica (Common Cord-moss): large mass of drooping green and orange capsules on coiled seta found around fire sites.
 

 

Lichens              Related link:  British Lichen Society

 

The lichen flora of mobile dune systems is limited and the ones found here are “mostly unexciting”. More information and a more complete species list can be found here. Ramalina fraxinea, Parmelia carporrhizans and Parmelia pastillifera have been recorded growing on Sycamores on site. The UK BAP species Pyrenocollema (Collemopsidium) pelvetiae has been recorded from seaweed, its favoured substrate, on the Exe and Teign estuaries and may occur within the recording area.

 

 

Fungi                  Related link:  British Mycological Society

 

Over 250 different species of macro-fungi have been recorded on site, but the current status of many is uncertain. Five of these species were new to science when first recorded here Conocye dunensis, Cortinarius fulvosquarrosus, Leptonia inocybeoides, Naucoria cephalescens and Nolanea sericeonitens.  Other species that regularly grow here, but are not identified to species, include puffballs, stinkhorns, bird’s nests, earthstars and eyelash fungi. The Blackening Waxcap Hygrocybe conica grows in around Greenland Lake, but numbers have declined recently, also around Greenland Lake and the Golf Course. Horse Mushroom Agaricus arvensis can be found. The Sand Stinkhorn Phallus hadrianii has been recorded from the Dune Ridge.

Along with other aspects of the marine biology of the recording area, this is a group for which there are currently no records available for the site. All records and help would be appreciated and of course credited.
