Mitthyridium crassum - Specimen 271
Description

Collection locality: Pahang, Malaysia
Elevation: 700 meters
Substrate: on tree 5 ft above ground

Collection information:
Ibrahim 392
Pahang, Taman Negara, trail from Merapoh to Gunung Tahan

This specimen (previously called Mitthyridium retusum) has many of the features of crassum, though is placed here within the jungquilianum clade. The two cpDNA sequences did not match Mitthyridium sequences or any related sequence (despite there being multiple sequences of Mitthyridium and relatives of rps4 and trnL on the GenBank) and thus were removed. Therefore, this placement is based strictly on the nuclear gene glyceraldehyde 3-phosphate dehydrogenase. It is possible though unlikely that this gpd sequence is a hybrid (and also a possibility that it is not a Mitthyrdium at all, but more data are needed to confirm).

Genes sequenced:
rps4
trnL
gpd - AF400904
